Serena Rodríguez came into the world on February 11, 1999, in Moreno, Buenos Aires province, Argentina. Her mother, Lorena Beatriz Rodríguez, was only 20 when she discovered her pregnancy. The father of her child, an abusive man, ended their relationship upon hearing the news and never recognized Serena Rodriguez as his daughter. As a result, Serena bore only her mother’s last name.
Lorena, now a single mother, faced the challenges of raising a child alone. To make ends meet, she worked tirelessly, leaving Serena Rodriguez under the care of her maternal grandmother, Nora, during her formative years. This arrangement fostered a deep bond between Serena and Nora, a connection that would remain strong throughout her life.
Over time, Lorena rebuilt her life, marrying a new partner and having more children. Serena eventually joined her mother, stepfather, and two younger siblings in their home. However, her relationship with her mother was often fraught with tension, leading Serena to frequently return to her grandmother’s house for solace.
Teenage Years and Love
By 2012, Serena moved back to Nora’s house after a particularly heated argument with her mother. It was around this time that she met Lucas Leal, a young man from her neighborhood. Despite the three-year age gap, the two quickly became close. On Serena’s 14th birthday, Lucas formally asked Lorena for permission to date her daughter.
Initially, their relationship was filled with the excitement of young love. Lucas frequently visited Nora’s home, and the couple was often seen together. But as time passed, Lucas’s behavior became controlling and jealous, leading to frequent arguments. Tired of the toxicity, Serena Rodriguez ended the relationship in 2014.
Shortly after, Lucas began dating another girl, Florencia, who became pregnant. Despite their history, Serena Rodriguez sympathized with Florencia, understanding the difficulties of growing up without a father figure.
At 15, Serena didn’t have a grand quinceañera due to financial constraints. Instead, her grandmother gifted her a laptop, a cherished item that Serena Rodriguez carried everywhere. She was a lively, well-loved teenager who had big dreams and confided in her friends about her struggles, including her hope of one day being acknowledged by her father.
Lorena and Nora pursued legal action to secure child support from Serena’s biological father. A court-ordered DNA test was requested, and Serena looked forward to using any financial support to fund her high school graduation trip.
The Day Everything Changed
By 2014, Serena was living with her mother again and commuting daily to a public school by bus. On June 23, 2014, she followed her regular routine. After school, she boarded her usual bus and rode home with a classmate, who got off a few stops earlier. Serena Rodriguez continued alone and got off at her usual stop, just a short distance from her home.
She was expected home by 6:30 PM, but by 7:00 PM, her absence raised alarm bells. Lorena, worried, began calling Serena’s friends and family. She even contacted Nora, hoping Serena had gone to her grandmother’s house. However, no one had seen her.
At 9:00 PM, Lorena reported Serena’s disappearance to the police. Officers began retracing her steps from school to the bus stop, while family members and neighbors searched the neighborhood. Despite their efforts, there was no sign of Serena Rodriguez.
Her family’s desperation grew as they contacted hospitals and scoured the area late into the night. What had started as an ordinary day ended in heartbreak, as Serena Rodríguez seemed to vanish without a trace.
A Chilling Morning Revelation
By the next morning, news of Serena Rodríguez’s disappearance had spread throughout her community. A classmate, who had shared the bus ride with Serena the evening before, provided information that redirected the search efforts to the vicinity of the bus stop. Around 9:00 AM, Serena’s aunt, Roxana Rodríguez, decided to inspect a nearby vacant lot, suspecting it might be along Serena’s path home.
As Roxana searched through trash and overgrowth, she was startled by the faint sound of a phone alarm. Following the noise, she uncovered a horrifying scene: Serena’s lifeless body lay hidden under a tree, partially obscured by garbage and tangled weeds. She was face down, still dressed in her school uniform, but her tracksuit pants were pulled down, raising the possibility of sexual assault. Multiple stab wounds marked her torso, stomach, and neck.
Nearby, Serena’s backpack, phone, and other belongings were found intact. A hunting knife, believed to be the murder weapon, was also located near her body. Bloodstains at the bus stop suggested that the attack began there before Serena Rodriguez was dragged to the secluded area.
A Community in Shock
The brutal discovery sent shockwaves through the neighborhood. Friends, family, and neighbors were consumed with grief and disbelief. Nora, Serena’s grandmother, begged authorities for a thorough investigation. Describing Serena Rodriguez as a sweet and innocent girl who had brought no harm to anyone, she urged witnesses—including the bus driver and passengers—to come forward with information.
Support poured in from the local community, who stood by Nora and Serena’s family in their call for justice.
Local police, a prosecutor from Moreno, and regional detectives launched a full-scale investigation. The intensity of the attack pointed to a crime of passion. Serena’s family, adamant that she had no known enemies or ongoing relationships, mentioned her recent breakup with Lucas Leal.
Lucas, who had a history of controlling behavior, had been attempting to reconcile with Serena Rodriguez in recent months. When investigators examined her phone, they uncovered several calls from Lucas in the days leading up to her death. He was also the last person she spoke to before her disappearance.

Lucas Leal Becomes a Suspect
On June 24, the day after Serena’s body was discovered, Lucas and his father voluntarily visited the police station to provide a statement. However, investigators quickly grew suspicious. Lucas had fresh cuts on his hands and arms, injuries consistent with the type of knife used in the attack. When asked casually about the cuts, Lucas claimed they were from a soccer game with friends.
During formal questioning, Lucas maintained that he had spent the evening grocery shopping with his mother before playing soccer at a local sports complex. His story, however, didn’t align with the timeline and evidence. Investigators informed Lucas that he was now the primary suspect in Serena’s murder, and he was arrested that same day.
Later that evening, police conducted a search of Lucas’s home. Items seized included clothing, a laptop, a larger knife than the one found at the crime scene, and muddy sneakers with apparent bloodstains. These items were sent for forensic analysis to determine whether the blood matched Serena’s DNA. Soil samples from the crime scene were also collected to compare with the mud on Lucas’s sneakers.
The preliminary autopsy report revealed the extent of the violence Serena Rodriguez endured. She had suffered 49 stab wounds, with the fatal injury being a deep cut to her neck that severed her carotid artery. Defensive wounds on her hands indicated that Serena had fought back during the attack. Authorities could not immediately confirm whether a sexual assault had occurred.
A Court Appearance
The following day, Lucas appeared in court for a hearing. Prosecutors questioned him about his injuries, the evidence collected from his home, and a text message he had sent to Serena shortly before her disappearance—the last message she ever received. Lucas refused to answer.
Citing femicide and premeditated cruelty as aggravating factors, the prosecutor requested that the judge detain Lucas on charges of aggravated homicide. The case, marked by its brutality, left the community reeling and determined to seek justice for Serena Rodriguez.
Prosecutors built their case around three critical factors: Lucas and Serena’s prior romantic relationship, the extreme violence of the attack, and Serena’s defenselessness during the crime. Investigators scrutinized text messages, social media activity, and witness testimonies to piece together the events leading up to the tragedy.
Between June 18 and the day of Serena’s murder, Lucas had bombarded her with obsessive and possessive messages. Despite being in a relationship with Florencia and having a child, Lucas’s social media profile still featured photos of him with Serena Rodriguez. A series of cryptic posts revealed his emotional turmoil, including one on June 1 in which he accused Serena of lying about loving him. Just days later, he posted another message professing his feelings and pleading for her attention.
One chilling piece of evidence found on Lucas’s phone was an image of him holding a sharp kitchen knife in a threatening pose directed at a teddy bear. Although it could not be presented as direct evidence, prosecutors saw it as a disturbing insight into his mindset.

Friends and Family Speak Out
Serena’s friends revealed troubling details about the couple’s relationship. They disclosed that Serena Rodriguez and Lucas had continued meeting in secret, even after their breakup. According to her best friend, Serena had agreed to meet Lucas on the day she disappeared. Friends also reported seeing bruises on Serena’s arms and back, injuries they believed were inflicted by Lucas. Some even shared threatening messages Lucas had sent to them, warning them to stay out of his relationship with Serena.
Nora, Serena’s grandmother, described their relationship as toxic and admitted she was aware they had resumed contact. Serena’s mother, Lorena, expressed shock at the extent of the abuse. “They kept me in the dark,” Lorena said. “I never knew the full story, only that Lucas was being investigated.”
Social media posts from Serena Rodriguez provided further insight into her feelings. In one post, she quoted a Thalía song, lamenting her choices in love. Another post hinted at her struggle to break free from Lucas despite her family’s warnings.
Lucas’s Defense and Florencia’s Role
Lucas’s mother claimed Serena Rodriguez was the one pursuing her son, presenting letters and messages as supposed evidence. “She was the one chasing him,” she insisted. “It’s unfair to spread lies about Lucas.”
Investigators also questioned Florencia, Lucas’s girlfriend at the time, who admitted to giving Lucas the knife later used in the crime. However, she denied any involvement, stating that the knife had been a gift from months prior. Her story was corroborated by the shop owner who sold her the knife, confirming that it had been purchased earlier.
“I wasn’t paying attention to their issues,” Florencia said. “I had no idea about their fights or what was happening on Facebook. When I found out what had happened to Serena Rodriguez, it broke me.”
Lucas’s alibi began to unravel under investigation. He had claimed to be playing soccer at a local sports complex, but surveillance footage from 15 cameras in the area showed no activity at the field during the time he said he was there.
On July 14, forensic experts presented damning evidence: Lucas’s DNA was found on the knife recovered at the crime scene. Soil samples from his sneakers matched the soil at the location where Serena’s body was discovered, and blood on the sneakers was confirmed to belong to Serena Rodriguez. Following these findings, Lucas’s lawyer withdrew from the case.
A Shocking Video Emerges
Two days later, the case took a dramatic turn when Argentine media outlets released a video that became a cornerstone of the prosecution’s case. The footage captured a heated confrontation between Serena and Lucas shortly before the crime. In the 15-minute clip, Serena Rodriguez confronted Lucas about his jealousy and obsessive behavior, highlighting the strain in their relationship.
This video supported the prosecution’s argument that the crime was one of gender-based violence. Combined with witness testimonies, forensic evidence, and Lucas’s history of controlling behavior, it reinforced the theory that Lucas had committed the crime out of possessiveness and rage.
With mounting evidence and public outcry, prosecutors formally charged Lucas with aggravated homicide, citing femicide and excessive cruelty as aggravating factors. The community rallied around Serena’s family, demanding justice for the young girl whose life was tragically cut short.

The Courtroom Drama Begins
On May 8, 2018, nearly four years after Serena Rodríguez’s tragic murder, the trial of Lucas Leal commenced. With his original lawyer no longer on the case, Lucas was represented by a court-appointed attorney, a move his family criticized as inadequate. They claimed the new legal strategy was flawed and left Lucas at a significant disadvantage.
The trial opened with emotional testimony from Serena’s mother, Lorena, who recounted the toxic nature of Serena and Lucas’s relationship. She highlighted the overwhelming evidence against him, including forensic findings and threatening messages Lucas had sent to Serena.
Florencia, Lucas’s former girlfriend, also took the stand. She confirmed that she had gifted Lucas the knife used in the crime but maintained her innocence, denying any involvement. Her testimony was consistent with earlier statements and corroborated by the store owner who sold her the knife.
Police officers and forensic experts presented the evidence that tied Lucas to the murder, including his DNA on the weapon, soil samples from his shoes matching the crime scene, and incriminating text messages exchanged with Serena shortly before her death.
Throughout the trial, Lucas showed no emotion, sitting silently and refusing to testify in his own defense.
The Verdict and Sentencing
After five days of intense proceedings, the court reached a unanimous decision. Lucas was found guilty of aggravated homicide, with femicide and premeditated cruelty cited as aggravating factors. He was sentenced to 50 years in prison, the maximum penalty for his crimes under Argentine law.
Serena Rodríguez’s murder and the trial’s outcome reverberated across Argentina, igniting widespread discussions about gender-based violence, particularly in young relationships. Advocacy groups and experts called for urgent action to educate teenagers about the importance of healthy relationships grounded in respect, trust, and communication.
The case highlighted the dangers of normalizing controlling and abusive behaviors and underscored the need for early intervention to prevent such tragedies. Serena’s story became a symbol of the urgent need for cultural and systemic change to protect young people from the devastating consequences of gender-based violence.
