It has now been nearly 25 years since 17-year-old Alissa Turney disappeared in Phoenix, Arizona, on the final day of her junior year in May 2001. What was initially treated as a possible runaway case has since evolved into one of the most closely followed missing-person investigations in the state, marked by years of stalled progress, renewed suspicion, and intense public attention.
Alissa reportedly left behind a note suggesting she was heading to California, where an aunt lived. However, several details quickly raised concerns among family members and investigators. She disappeared without her cellphone, her vehicle, or her personal belongings, including nearly $1,800 in savings. For those who knew her, these actions did not align with plans she had previously discussed about finishing school and building her future.
Born in 1984, Alissa grew up in Phoenix in a blended family. After her parents divorced, her mother remarried Michael Turney, who later legally adopted Alissa and her younger sister Sarah. Following the death of their mother from cancer, Michael became the primary caregiver. Over time, friends of Alissa described increasing tension at home, and some later reported that she felt closely monitored and restricted in her daily life.

On May 17, 2001, Alissa left school early after telling her boyfriend that Michael would pick her up. According to Michael’s account to police, he took her out for lunch that day, during which they argued, before dropping her back at home in the early afternoon. Hours later, he reported her missing and claimed she had run away.
Investigators, however, soon encountered inconsistencies. The alleged trip to California was never verified, and no one reported seeing or hearing from Alissa after that day. Her belongings remaining at home further complicated the runaway theory. Despite this, the case initially received limited investigative momentum.
Years later, in 2006, the case resurfaced after a prison inmate falsely confessed to killing Alissa. Although investigators quickly determined the confession was unreliable, it prompted a renewed review of the case files and early evidence.
By 2008, authorities formally reopened the investigation and conducted extensive interviews with people close to Alissa. Several acquaintances described a controlling household environment and said Alissa had expressed discomfort regarding her stepfather. At the same time, Michael Turney denied all allegations and maintained that his daughter had voluntarily left.
During this period, investigators also attempted to search Alissa’s personal room but were denied access by Michael, adding further tension between him and law enforcement. Eventually, authorities obtained a search warrant for the property.
The search did not uncover evidence directly linking to Alissa’s disappearance. However, it did reveal a separate and serious discovery: a large stockpile of weapons, including firearms, homemade explosive devices, and written materials describing a planned attack on a union building. Michael Turney was later convicted on federal charges related to illegal possession of destructive devices and served time in prison. Still, this case remained legally separate from the investigation into Alissa.
As the years passed, the case remained unsolved until renewed public attention emerged largely due to Alissa’s younger sister, Sarah Turney. Through social media campaigns, a podcast, and widespread online advocacy, Sarah brought significant visibility to her sister’s disappearance and helped keep the case in the public eye.
This renewed pressure contributed to a major development in 2020, when Michael Turney was arrested and charged with second-degree murder in connection with Alissa’s presumed death. The arrest marked the first formal homicide charge in the case nearly two decades after she vanished.

The trial began in 2023 and included testimony from investigators, family members, and individuals familiar with the early investigation. Prosecutors also presented recorded statements and past interviews that they argued reflected longstanding concerns about the home environment and Michael’s behavior. However, the defense emphasized a critical issue: the absence of physical evidence.
After several days of proceedings, the court ultimately ruled that the prosecution had not met the legal burden required for conviction. With no body, no confirmed crime scene, and no direct forensic evidence proving death, the judge granted a motion for acquittal. Michael Turney was released in July 2023.
As of today, Alissa Turney has never been found. Michael continues to deny any involvement and maintains he does not know what happened to her. Meanwhile, Sarah Turney remains convinced that her sister is no longer alive and continues her long-standing effort to seek answers in a case that, despite decades of investigation and public attention, remains unresolved.
