OSBI To Release More Details And Evidence In 1981 Moore Cold Case

 It's been 34 years and the murder of Tracey Neilson still remains a mystery. In January, the OSBI shared an old piece of evidence hoping to give new life to the cold case. Now, investigators plan to reveal even more.

In January, the OSBI thought an old cable service log found at Tracey Neilson's apartment would give investigators new leads. Despite dozens of tip, the owner of the ticket book has never been located.

On Friday, the OSBI will share more details and evidence hoping it'll help them find her killer.

Investigators say on Neilson's 21st birthday her husband of five months came home and found her brutally stabbed to death.

The newlywed couple lived in the Jamestown Square Apartments in Moore.

A cable service log with a signature in the bottom left corner is still considered crucial evidence. The last ticket in the book is for work at Neilson's home with the time stamp of 11:51 a.m. But, the OSBI has only been able to determine it belonged to someone who worked for Southwestern Bell.

An eye witness spotted Neilson at her apartment around noon the day of the murder.

“We've had to live with the fact that we may never know who took her life that day and we have to wonder every day why did they do that. How could they do that?” said Cindy Young, Tracey’s sister.

The OSBI plans to hold another press conference Friday, July 10, to reveal a possible souvenir the killer took from Neilson's home. Agents will also announce the reward for anyone with information or evidence on this case.
