Westminster, Colorado, is the picture-perfect suburban American town. With spacious parks, serene lakes, and charming one- or two-story homes, it’s a community where children roam freely, enjoying wide streets and safe neighborhoods. In this tranquil setting, Jessica Ridgeway was born on January 23, 2002, to parents Sarah Ridgeway and Jeremy Bryant.
Jessica was a bright and creative ten-year-old attending Whitt Elementary School. Known for her perfect attendance and her role on the junior cheerleading team, she was cherished by her teachers for her intelligence and respectful nature. At home, Jessica loved writing song lyrics, playing in the snow, and caring for her black-and-white dog. She had blonde hair, striking blue eyes, and an unmistakable energy that lit up the lives of those around her.
A Chilly Morning Turns Ominous
On the morning of October 5, 2012, Westminster was blanketed in snow. Jessica Ridgeway, dressed warmly in jeans, a black jacket with pink stripes, and black boots, grabbed her pink-and-black Victorious-themed backpack and called a classmate to arrange their usual walk to school. After gaining permission from her friend’s father, the two were set to meet at 8:30 AM near Jessica’s home.
However, Jessica never arrived at the meeting spot. Assuming she had taken another route, the friend’s father drove his daughter to school, unaware that this simple change in routine marked the start of a tragedy.
At 10:10 AM, Whitt Elementary School left a voicemail for Jessica’s mother, Sarah, informing her that Jessica Ridgeway hadn’t shown up. Exhausted from her night shift, Sarah didn’t hear the message until 4 PM. Panic immediately set in as she contacted the police and began searching the neighborhood. Knocking on doors and visiting the school yielded no answers.
By the morning of October 6, the search for Jessica Ridgeway became a community-wide effort. Volunteers, neighbors, and police combed the snowy streets and parks near her home. An Amber Alert was issued, and purple ribbons—Jessica’s favorite color—were tied along her presumed route to symbolize solidarity and hope.

A Disturbing Discovery
On October 7, a breakthrough came when a backpack was found near Andrew Drive and Kristinson Avenue, roughly 8 miles from Jessica’s home. Inside were her purple-framed glasses, a water bottle with her name, and wet clothing. This discovery raised critical questions: How did the bag end up so far from her route? Could someone have taken her by force?
Investigators collected DNA evidence from the bag, which linked the case to a prior attempted abduction in May 2012 near the Brownfield Reservoir. However, the suspect’s identity remained unknown, leaving law enforcement scrambling for answers.
On October 11, search efforts came to a heartbreaking end when human remains were found near an abandoned cabin, 10 miles from Jessica’s home. The forensic analysis confirmed the remains belonged to a young girl. In a chilling twist, the body had been dismembered and meticulously cleaned, leaving investigators to piece together the grim details.
The discovery marked a tragic turning point. For days, the community had clung to hope that Jessica Ridgeway might still be alive. The realization that her life had been violently taken was a devastating blow to everyone involved.
The aftermath of Jessica’s disappearance galvanized the Westminster community and law enforcement agencies alike. Purple ribbons remained a symbol of remembrance, and investigators worked tirelessly to bring the perpetrator to justice. The tragedy highlighted the importance of vigilance in protecting children and underscored how a close-knit community could rally in the face of unthinkable loss.
An Expansive Investigation
As the investigation into Jessica Ridgeway’s disappearance escalated, authorities left no stone unturned. Properties were searched, GPS tracking technology was deployed, and hundreds of interviews were conducted. Over 500 DNA samples were collected and sent to the Colorado Bureau of Investigation for thorough analysis. Among the recovered evidence were items of Jessica’s clothing, confirming the worst fears. What had started as a desperate search for a missing child had now turned into a hunt for a killer.
On October 17, 2012, at around 8 PM, investigators arrived at a residence in Westminster. This house belonged to Mindy Sigg, her 17-year-old son Austin Sigg, and his younger brother. During the visit, FBI agents spoke with Mindy but did not conduct a search of the premises at that time.
Austin Sigg, born on January 17, 1995, endured a childhood marked by family turmoil. His parents, Mindy and Robert Sigg Jr., divorced when Austin was only five. Robert’s troubled history, including domestic violence, assault, and fraud, left a significant impact. Multiple failed marriages and legal troubles added instability to Austin’s life.
From an early age, Austin struggled with reading, writing, and concentration. Teachers suggested he be evaluated for attention deficit disorder, which only added to his academic difficulties. Outwardly, however, Austin seemed like a normal teenager. He had a girlfriend from a Christian youth center, played video games like Call of Duty, and enjoyed forensic science and psychology.
However, beneath this façade was a deeply disturbed individual whose dark obsessions grew over time.

A Hidden Obsession
Austin’s mother discovered his disturbing tendencies when he was just 13 years old. She uncovered a vast collection of child pornography on his computer and sought professional help. Diagnosed with an anxiety disorder, Austin began therapy and medication. Despite these efforts, his behavior worsened. He became adept at hiding his activities, while his consumption of violent and graphic pornography escalated.
By his teenage years, Austin’s interest in crime and forensic science had evolved into a sinister fixation. He researched methods for immobilizing victims, experimented with restraints, and even searched for information on chloroform, all while masking his intentions as school projects.
On May 28, 2012, Austin made his first known attempt to abduct someone. He attacked a 22-year-old jogger, attempting to subdue her with a cloth soaked in an unknown substance. Dragging her into nearby bushes, he was thwarted when the woman fought back and escaped. Though he fled the scene, the failed attempt emboldened him to target someone more vulnerable next time.
The Abduction of Jessica Ridgeway
On the morning of October 5, 2012, Austin sat in his Jeep Cherokee, watching as Jessica Ridgeway walked alone to meet a friend before school. When she came close, he grabbed her and forced her into the vehicle. Using nylon ties, he bound her arms and legs as she screamed. He falsely reassured her, claiming she would not be harmed.
Driving aimlessly for a while, Austin eventually returned to his home, parking in the garage to ensure privacy. He carried Jessica Ridgeway upstairs to his room, where he forced her to take a bath. Afterward, he dressed her in his own clothes and placed her soiled clothing into her backpack. To calm her, he cut her hair, showed her a movie, and lied, telling her she would soon see her mother again.
As Jessica resisted, Austin attempted to strangle her with plastic ties but failed. He then used his hands, suffocating her over the course of three agonizing minutes. When she showed faint signs of life, he filled a bathtub with water and submerged her face-down, ensuring she could no longer breathe.
After confirming her death, Austin retrieved a hacksaw and knife. He dismembered her body, discarding her internal organs and placing the remains in black trash bags. He temporarily stored these in a pool shed behind his house, a chilling testament to his calculated cruelty.
The investigation turned a corner when authorities released photos of a wooden cross found with Jessica Ridgeway’s remains. Recognizing the cross as one often worn by Austin, a friend contacted the FBI. This tip led investigators back to the Sigg residence. Although officers interviewed Austin with his mother’s consent, no immediate evidence warranted his arrest or a search of the home.
As the investigation continued, the truth about Austin Sigg’s crimes began to unravel. His actions shocked the community and served as a harrowing reminder of how a seemingly ordinary teenager could harbor such unimaginable darkness.
A Massive Effort, a Shocking Breakthrough
The investigation into Jessica Ridgeway’s case had become a monumental operation, involving over 1,000 individuals and 75 local, state, and federal agencies. Despite mounting frustration, investigators were determined to find the killer. That moment came unexpectedly on the night of October 22, 2012.
Feeling unwell, Austin Sigg slept in his mother’s bed. The next morning, he confessed to her that he had done something terrible. Referring to himself as a “monster,” Austin admitted his guilt when his mother, Mindy Sigg, asked if it was related to Jessica Ridgeway. That evening, at 7:30 PM, Mindy called the Westminster Police Department, reporting that her son wanted to turn himself in for Jessica Ridgeway’s murder.
The 9-1-1 operator was stunned by the call. When police arrived at the Sigg home, they found Mindy sobbing as she embraced Austin. Initially skeptical of the confession—since the investigation had focused on an adult male suspect—officers quickly realized Austin’s detailed account of the crime was credible.
A search of the house uncovered black plastic bags in the basement. Though officers waited for forensic experts to open them, the texture and weight suggested they contained human remains, including a child’s skull.
Austin waived his rights and fully cooperated with investigators. Over the course of a six-hour interrogation, he described the abduction, murder, and dismemberment of Jessica Ridgeway in chilling detail. He also confessed to the attempted abduction of a 22-year-old jogger earlier that year. Calling himself a “monster,” Austin admitted being driven by sexual impulses. Though he initially denied sexual assault, he later admitted to it.

DNA Evidence and a Critical Oversight
The investigation faced a temporary setback when Austin’s initial DNA tests did not match samples taken from Jessica Ridgeway or the jogger. The mismatch was due to an administrative error—his sample had been misplaced in an unreviewed batch. Once the oversight was corrected, DNA results confirmed a match. Samples from Jessica’s body and the jogger’s shirt aligned with Austin’s, solidifying his guilt.
Austin revealed that he had placed a handcrafted wooden cross on Jessica’s body and etched three small parallel marks into it. Investigators had not disclosed these details to the public, further corroborating his confession. During questioning, Austin admitted that on October 5, 2012, he had gone out “hunting” for a victim, encountering Jessica Ridgeway for the first time that morning.
Austin chillingly confessed that his intent had always been to kill, selecting the location for the crime because he was familiar with the area, having attended Whitt Elementary School as a child.
Courtroom Revelations and Defense Arguments
On February 22, 2013, a preliminary hearing revealed the horrifying details of Jessica’s abduction and murder. Austin’s defense team argued that he had endured a life filled with challenges, including:
- A fall his mother had suffered during pregnancy.
- A complicated birth that temporarily deformed his skull.
- Multiple surgeries and chronic intestinal issues during his childhood.
Defense experts suggested Austin’s mental and emotional immaturity prevented him from fully understanding his actions. However, prosecutors countered that the crime was meticulously premeditated, citing his attempted abduction in May 2012 and Jessica’s murder four months later.
The judge dismissed the defense’s claims, emphasizing that none of the arguments excused the heinous nature of the crime. A clinical psychologist testified that Austin displayed necrophilic tendencies and confirmed he had planned the crime in detail.
Austin was charged with 18 counts, including Jessica Ridgeway’s murder and the assault on the jogger. Two days before his trial, he pleaded guilty to all charges. During court proceedings, as the District Attorney described Jessica’s abduction and murder, her mother, Sarah Ridgeway, was unable to endure the harrowing details and left the courtroom.
A Somber Sentencing Phase
On November 18, 2013, the sentencing phase of Austin Sigg’s trial began, giving Jessica Ridgeway’s family a chance to share the profound impact of her loss. Family members spoke of the light Jessica brought into their lives and the deep pain caused by her brutal murder. In an emotional interview, Jessica’s grandmother expressed her sorrow, reflecting on how unimaginable it must be for Austin’s mother to live with the knowledge of her son’s horrific actions.
Because Austin was a minor at the time of the crime, he was ineligible for the death penalty. However, the prosecution sought the maximum punishment, ensuring that Austin would never again walk free.
On November 19, 2013, the judge delivered a life sentence without the possibility of parole for Jessica Ridgeway’s murder. Defense attorneys argued that, under Colorado law, Austin should be eligible for parole after serving 40 years because of his age. However, the judge firmly rejected these claims, stating that such an atrocious case demanded the harshest punishment. He dismissed suggestions that the sentence was unconstitutional or constituted cruel and unusual punishment.
In addition to life without parole, Austin received an additional 86 years for other crimes, including the sexual assault of a child and charges related to the attack on the jogger. While delivering the sentence, the judge remarked that “evil is real” and that it had manifested in their community on October 5, 2012, through the actions of Austin Sigg.
Community and Family Reactions
Following the sentencing, the District Attorney expressed confidence that the punishment ensured Austin would never leave prison, safeguarding the community. Mindy Sigg, Austin’s mother, broke down multiple times as the court recounted her son’s heinous crimes. Yet, as the sentence was read, she sat calmly, looking at her son. Austin, in contrast, chose not to address the judge and showed no emotion as the verdict was announced. The self-proclaimed “monster” left the courtroom silently, shackled and under heavy guard.
A year later, the Colorado Department of Corrections transferred Austin to an undisclosed out-of-state prison for his safety and privacy, a common measure for high-profile inmates.
Jessica’s mother, Sarah Ridgeway, made it clear that Austin would no longer hold power over their family. She stated that once they left the courtroom, they would “forget his name forever” and focus on remembering Jessica Ridgeway and the love she brought into their lives.
On the first anniversary of Jessica’s disappearance, the community united to open the Jessica Ridgeway Memorial Park in Westminster. Filled with purple accents—Jessica’s favorite color—the park became a tribute to her memory and a symbol of the love and hope that her family and neighbors continue to share.
A New Chapter of Hope
On October 15, 2017, Sarah Ridgeway welcomed a new member to her family: Anna Christine, Jessica’s younger sister. Anna shares Jessica’s middle name and her beautiful blue eyes. According to Sarah, the family felt overjoyed by Anna’s arrival and certain that Jessica would have adored her little sister.
Both Sarah and Jessica’s grandmother plan to share Jessica’s story with Anna when she is old enough, ensuring her memory is passed down with love, not fear. The family is determined to let the legacy of Jessica Ridgeway’s light guide their future, refusing to let tragedy overshadow their joy.
