TUCSON - It was a case that stunned Tucson, a 15 year-old student from Sahuaro High School, found brutally murdered with her hands tied behind her back.
Margaret Carabetta's body was found by two women who were walking in the desert on April 9, 1982.
To help solve the case, detectives are using the technological advances from today that were not available around the time of the murder. DNA is being collected and compared to the people who had last seen Margaret alive.
Detectives back then collected several items of evidence and have been able to identify people, and collect DNA.
Margaret's boyfriend was one of the last people to see her. Her boyfriend has since died, however, he has children and his parents are still alive.
Detective Charles Garcia does not believe that Margaret's boyfriend is a suspect at this time. He is just one more lead that has to be tracked down in this case.
The most important lead comes from the night Margaret disappeared.
On April 7th, Margaret was on the phone with a friend; at about 11 p.m. Margaret hung up the phone because she heard a knock at the door.
Most likely, the person who came to the door that night was the person who killed Margaret.
In 1987, a profile was done of the killer. It was reported that it was more than likely a "spurned lover". Detective Garcia adds, "In the end of it, it's a 15-year-old girl who didn't deserve to die in the brutal manner in which she died."
Detectives are asking for the help of the public to help solve this case. If you have any information please call 88-CRIME or 911.
