Authorities in California’s Santa Clara County are trying to identify the maker or owner of a quilt that was found on the body of a mother of two who was strangled to death 25 years ago.

The Santa Clara County District's Attorney's Office released a photo of the quilt on Thursday, hoping that someone will recognize it and come forward with information that will lead to whoever killed 38-year-old Cathy Zimmer.

"Cathy Zimmer was slain two-and-a-half decades ago, but her family has never forgotten her,” Deputy District Attorney Ted Kajani said in a news release. "We, too, have never forgotten her. We, too, have never given up on her case. We are asking the public to take a look at this quilt and call us if you know anything about it."

Zimmer was found dead in the backseat of her car in a San Jose airport parking lot on March 10, 1989. She was covered by the quilt. She vanished two days earlier after driving her kids to school, having lunch with a friend and attending college.

Zimmer's daughter, Debbie Lawrence, now 39, was a teen when her mother was killed. She told the San Jose Mercury News her family has been contacted by several detectives over the years, but they haven't lost hope.

"It's wonderful," Lawrence said of the renewed push to find her mother's killer. "I'm just keeping my fingers crossed that somebody might remember something."

Asked why police never before asked for the public's help with the quilt, Kajani and Investigator Michael Brown told the San Jose Mercury News that detectives initially wanted to hold back some information only the killer would know about, such as the method of strangulation.

While no one close to Zimmer was able to identify the quilt after her murder, Kajani said the photo will now be seen by a much bigger audience on social media.

Anyone with information on the quilt or Zimmer’s killing is asked to contact the Santa Clara County District's Attorney's Office at 408-808-3760.
