Cable repair ticket key to solving 1981 murder?

OKLAHOMA CITY - The Oklahoma State Bureau of Investigation (OSBI) is asking the public for help in identifying the person who signed a cable repair ticket book in connection with the 1981 stabbing death of a woman in her home in Moore.

University of Oklahoma student Tracey Neilson was found stabbed to death on her 21st birthday on Jan. 5, 1981. Despite combing through close to 1,500 leads, authorities are no closer to cracking the case than they were on day one, reports CBS affiliate KWTV.

On Monday, the 34-year anniversary of the murder, officials held a news conference and introduced a piece of evidence found at the crime scene - a cable repair ticket book. The last ticket in the book is for work at Neilson's home at 11:51 a.m. that day. A scribbled signature or initials is in the bottom left hand corner of the ticket and the OSBI is hoping someone will recognize the writing and be able to identify it.

The book doesn't include a company name and OSBI director Stan Florence said Monday that investigators have been unable to identify the company.

Jeff Neilson, who was married to Tracey at the time of her death, told KWTV that they had cable television at their home, but he doesn't remember there being a problem with it.

Authorities say an $11,000 reward is being offered to anyone with information leading to an arrest and conviction in the case. Tips can be made to the OSBI at 1-800-522-8017.
