Lisa Jameson, also known by her maiden name Lisa Collins, disappeared in 1991 at age 23. Her case remains unresolved, and her son, Kyle Collins, who was 2 at the time, is still seeking answers. ABC15 Arizona reports that Jameson was living in Gilbert when she vanished.

The last reported sighting was near McQueen Road and Chandler Boulevard in Chandler, after Jameson dropped off a co-worker following an overnight shift, according to Gilbert police as reported by ABC15. KTAR News places the sighting at about 7:15 a.m. on November 4, 1991, after Jameson finished an overnight shift at an electronics store. Police said she was married, had a young son and was believed to be pregnant.

Investigators have said Jameson's personal belongings were left behind and that no money was ever withdrawn from her bank account — details that have long fueled her family's belief that she did not simply walk away. Nearly a month after she vanished, her red 1989 Pontiac LeMans turned up in a Phoenix parking lot. The station's report places the car near 40th Street and Washington, while KTAR News and FOX 10 Phoenix both put the date at December 3, 1991, and describe the location as an adult bookstore parking lot — with FOX 10 specifying 48th Place and East Washington Street. KTAR notes that no evidence pertaining to her disappearance was found inside the car.

A Son Who Grew Up Without Answers

Collins was 2 when his mother disappeared. He has told ABC15 that he only gradually came to understand the unanswered questions surrounding her case.

ABC15 reports that Collins has sought more information about the investigation over the past decade. He continues to speak publicly about the case.

Turning Grief Into Music

ABC15 Arizona reports that Collins releases music as Sincerely Collins and released a new album on Monday. He has said he hopes his music and public comments will bring renewed attention to his mother's disappearance.

Collins has said he believes his mother's case has not received enough attention. FOX 10 Phoenix reports that Gilbert police have not publicly said foul play was involved; what happened to Jameson remains unresolved.

Resources for comparing cases

As general context, NamUs describes itself as a national repository and resource center for missing, unidentified and unclaimed person cases. NamUs also says family reference DNA profiles are searched against CODIS's Unidentified Human index, not criminal indices, as explained on its DNA services page. This information does not establish whether Jameson's case is listed in NamUs or whether her family has submitted DNA samples.

ABC15 says its reporters have been reviewing case records that raise additional questions and are following up with Gilbert police about the case's current status. The outlet has not reported a resolution.
