Tracy Allen & Patty Vaughan

December 1, 2010 By Alice

Tracy Allen & Patty Vaughan

Tracy Allen & Patty Vaughan are just two cold cases handled by the Texas Bexar County Sheriff’s Office but they can use your help in two cases:

Tracy Allen

In 1986, Tracy Allen (18) was found dead in Hondo Creek, Texas. Cause of death: strangulation. She went missing September 9 and was found on September 13, 1986.

At the time that she disappeared, nothing was out-of-order. Tracy’s room was as she left it with all her personal items and belongings in place. Nothing pointed to her running away or even that an attempt was made to pack a bags This led people to believe that she had every intention to return home later that day.

The links to the newspaper articles I used for this post are all disabled. One had a video clip. From that clip it was easy to see that the person responsible for her death knew the area well. Tracy’s body was found close to her home. A stranger would not dare to take the risk to be seen so close to Tracy’s home.

I have not been able to find out yet whether Tracy died where she was found. Nothing in the public domain so if you have active links to news articles please let me know.

If you have any information please call Crime Stoppers at 210- 224-STOP.

There is a lot of information on the web but much of it contradicts itself or leaves huge gaps in the time lines.

On Dec. 25, 1996, Patty disappeared from her home and has never seen again. Patty’s blue 1991 Dodge Caravan was discovered on December 26, 1996, one day after she was last seen. It was abandoned on the shoulder of Loop 1604, just west of Highway 37 in South Bexar County, with the driver’s side front tire deflated. This was about 15-20 miles from her home and 5 miles from her office at Quinney Electric.

The newspaper articles stated that the caravan was cleaner than usual. The driver’s seat was pushed back, blood was found under, near, and around the backseat, and one of the tires was flat. Tests revealed that the tire had been intentionally deflated. DNA tests confirmed that the blood found in the caravan, belonged to Patty.

Luminol is often used by crime scene investigators to find blood evidence because of its reaction to hemoglobin, which causes the chemical to give off a blue glow. After preliminary Luminol tests in the home, strong blood reactions were found in the bedroom, the master bath, and master closet area. They also discovered blood on a mop inside the house. DNA testing proved that blood found inside the house, was Patty’s.

On May 15, 2008, after Bexar County investigators had taken over the cold case, they decided to investigate a pile of clothes found inside Patty’s caravan. They found a red workman’s jumpsuit inside a pile of men’s clothing on which Vaughan’s blood was found back in 1996. “What jumped out is that this jumpsuit seemed to be a worker… automotive repair or plumbing,” Officer Ramirez said. Of course, that pile of clothing should have been scrutinized long before these officers decided to take over the case and it makes you wonder what else was in the caravan.

 Back to the jumpsuit…

“JM” could be a person, a company, a brand or, a personal abbreviation. I’d like to know what the quality of that jumpsuit was, the brand, where it was sold, how the stitching of the emblem was done (by machine or by hand), was there anything else on the shirt such as written initials on the tag or any other biological residue that can be tested for DNA?

Patty left three children behind and they want to know exactly what happened to their mother.

Author Notes

Since 2009, I write about unsolved cases that need renewed media attention. I only do research and leave active investigations to the authorities.

My posts cover homicides, missing and unidentified people, wrongful convictions, and forensics as related to unsolved cases.

On book reviews: I only review select works of true crime, crime fiction, and historical fiction/mysteries. The stories have to fit my website's theme, tone, and research. It is my prerogative to not review a book. Please check the FAQ page for more.

My databases are free to the public. Cases are sorted by the victim’s last name.

If you have any questions about my website please check the Frequently Asked Questions (FAQ) page, the About page, and the tabs in both menu bars. If you cannot find the answers there, please contact me.

Thank you,
