OSBI Reveals Evidence In Moore Cold Case From 34 Years Ago

The Oklahoma State Bureau of Investigations (OSBI) said they hope an old piece of evidence, finally able to be shared with the public, will breathe new life into a cold case from three decades ago.

Tracey Neilson, 21, was found stabbed to death in her home 34 years ago, Monday.

Investigators have combed through close to 1,500 leads, none of which gave them the big break they needed.

Investigators said they hope an old cable service log will bring them closer to finding Tracey Neilson's killer.

The newly 21-year-old Tracey Neilson spent her birthday morning running errands around town before returning home to her Jamestown Square Apartment.

"There are eyewitnesses who put her at her home in Moore just before noon that day," said Stan Florence, OSBI Director.

Five hours later, Neilson's husband of five months came home to find his bride had been stabbed numerous times and brutally murdered.

Neilson's killer still lives free 34 years later.

"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?" Tracey's younger sister, Cindy Young asked.

But the small cable service log may give investigators the break they've been waiting three decades for.

"The last ticket in this book is for work at Tracey's home at 11:51 on the morning she was murdered," said Florence.

The ticket, quite possibly, documented the last moments of her life.

The OSBI doesn't know who the book belongs to or what company the person worked for at the time.

But a signature in the bottom left corner of the page is now considered crucial evidence in this case.

"I'm begging you; please come forward. Please just do the right thing because it's time. It's time to do the right thing," said Young.

A finger print from the Neilson home was collected the day of the murder. Investigators have yet to identify its owner, though.

Authorities said an $11,000 dollar reward is now offered to anyone with information leading to an arrest and conviction.
