In the early morning hours of October 20, 1995, police in Greeley, Colorado, responded to a report of a missing woman. Tina Sanderville, a 23-year-old nurse, had failed to return home the day before, and her family was frantic. Hours later, officers found her car abandoned just four blocks from the home of her estranged husband’s aunt, the place where she had planned to meet him that morning to finalize their divorce paperwork. When officers knocked on the door again, the aunt insisted John Sanderville was not there.
Then a loud crash came from the side of the house. John, shirtless, had leapt from a bedroom window and was trying to flee. Police caught him quickly and arrested him, though not for Tina’s disappearance. The charge was an outstanding felony trespassing warrant tied to an earlier stalking case.
But what investigators noticed at the station deepened their alarm. John had fresh scratches across his chest and neck, dirt packed beneath his fingernails, and in his car they found Tina’s credit cards, a shovel still wet and caked with mud, a 9mm handgun, rope, a flashlight, and a bucket. Tina Torres was born on March 17, 1972, in Valparaiso, Indiana, and raised in Windsor, Colorado, as the second of nine children. She was a standout student at Windsor High School, earning letters in track, volleyball, and basketball, competing in the knowledge bowl, playing trumpet in the band, and singing in the choir.
She went on to study nursing at Aims Community College, where she discovered a passion for oncology. It was there she met John Sanderville, a radiology student. Their connection grew quickly, and in 1991 they married in the Colorado Rocky Mountains, certain they were building a future together. Tina later transferred to the University of Northern Colorado, where she graduated in the top five percent of her nursing class in 1995.
The marriage began to unravel just five months after the wedding, when John was arrested for stalking a female coworker and breaking into her home. He served five weeks in jail. Tina then learned this was not a lapse in judgment but part of a long pattern. John had a history of watching women without their knowledge, breaking into their homes, hiding for hours, and taking personal items as keepsakes.
His record included repeated arrests for stalking, harassment, and unlawful entry. In March 1993, a woman named Wendy Foust reported a man tailing her car. She noted his license plate, and police traced it to John. Each time he was confronted, he promised Tina he had changed.
Those promises collapsed in August 1995, when another woman discovered John hiding inside her closet. Tina then made a decision. She moved into a new apartment and filed for divorce, determined to rebuild her life. John refused to accept the separation.
He first threatened to take his own life, then threatened hers. Tina hoped the legal process would bring closure, but she did not know how far he was willing to go. On October 19, 1995, after finishing an overnight nursing shift at North Colorado Medical Center around seven in the morning, Tina prepared for a meeting she dreaded. She had to meet John to resolve paperwork and an IRS issue required to finalize the divorce.
Her sister Susan later recalled that Tina was uneasy about meeting him alone, and asked Susan to come along, but Susan could not leave work that morning. Before they hung up, Susan asked her to call right after the meeting. Tina promised she would. The call never came.
By 12:30 that afternoon, Susan was worried. She contacted their mother, Mary, who drove to Tina’s apartment and found it empty. No sign of Tina, no sign of her car. Mary went to the home of John’s aunt, where Tina had planned to meet him.
The aunt insisted John was not home, but something caught Mary’s attention. Tina’s jacket was sitting on the kitchen table, as if she had been there recently. By nine that evening, Mary reported her daughter missing. Hours later, police located Tina’s car four blocks from the aunt’s home, and the search for John led to his arrest and the discovery of his car’s contents.
A chilling tip soon emerged. John may have buried Tina in an open grave at Sunset Memorial Gardens, the cemetery where he worked. Detectives combed the grounds, inspecting open graves and exhuming bodies in a desperate search. They expanded to reservoirs, wooded areas, and remote locations.
Tina’s whereabouts remained unknown, and the investigation went cold. Years passed. In 2010, John Sanderville was tracked down at his home in Las Vegas and arrested. Authorities charged him with first-degree murder, reasoning that enough time had passed to assume Tina was no longer alive.
Her bank account had sat untouched since October 1995. Her nursing license had expired without renewal. Her credit cards and student loans had long been sent to collections. John was extradited to Colorado, where the trial became one of the most extensive and expensive in Weld County history, costing over $110,000 and lasting longer than any prior trial in the area.
The courtroom heard harrowing testimony. Wendy Foust recounted how John followed her in March 1993, and how she ran into the Tribune office only to have him walk in moments later, claiming he was there to place an advertisement for a piano. James Tiner, who had met John at a bar the day before Tina disappeared, testified that John commented during a conversation about women, “Too bad you just can’t kill them. ” Jennifer Carr, a former high school girlfriend, described how John repeatedly broke into her home after their breakup.
On one occasion, he pressed a knife to her throat and threatened to take her into the mountains and chop her into pieces so no one would ever find her. Tina’s family, friends, and coworkers testified that she had confided in them for years, warning that if anything ever happened to her, John would be responsible. In total, 137 witnesses took the stand for the prosecution. John Sanderville was convicted of first-degree murder and sentenced to life in prison.
But in 2016, the conviction was overturned, and a second trial was scheduled. The case, which had haunted Colorado for over two decades, appeared destined to drag on further. Three weeks before the retrial was to begin, John made an unexpected move. He offered to reveal the location of Tina’s remains, but only in exchange for a guilty plea to a lesser charge of second-degree murder, which carried a lighter sentence.
The offer confirmed what detectives had suspected for more than twenty-two years. The tip they received decades earlier had been credible all along. Tina’s body was found beneath the grave of a World War II veteran who had died just two days before she vanished. John had buried her in the middle of the night on October 20, 1995, placing her only two feet beneath the man’s pre-dug grave before the funeral.
Her remains were wrapped in a blanket and sealed with duct tape, a silent testament to the cruel planning behind her murder. For 7,826 days, the location of her body had remained a mystery, tormenting her family and frustrating investigators. Tina was finally laid to rest, bringing a measure of closure to those who had waited so long for justice. As part of the plea deal, John received a twenty-five-year prison sentence with parole eligibility, crediting time already served.
He became eligible for parole in 2020, but it was denied. His next parole hearing is scheduled for January 2026, with an expected release date projected for 2032. He remains incarcerated at Trinidad Correctional Facility. Tina Torres’s story remains a devastating account of how a life full of hope and promise can be taken away, and how the warning signs leading up to tragedy are too often overlooked.
Her case has since sparked conversations about mental health, domestic violence, and the importance of early intervention. Her family and community have carried her memory forward, advocating for stronger safeguards and better resources for those in crisis. Justice brought accountability, but it could never restore what was lost.
