Investigation Discovery Features the 1977 Murder of 17-Year Old Santa Clara Resident Mary Quigley

Investigation Discovery has a new series, Murder Book, that will feature the 1977 murder of 17-year old Santa Clara resident, Mary Quigley on Tuesday, December 9 at 9:00pm (TV Channel 14, AT&T Channel 260, DISH Channel 192, Comcast Channel 271, DirectTV Channel 285).

Mary Elizabeth Quigley (February 28, 1960 – September 10, 1977) was a senior at Santa Clara High School and was attending a party the evening of Friday, September 9. Her body was found the next day approximately 300 yards away in Washington Park (now War Memorial Park). She had been raped and strangled.
No immediate suspect was identified and the murder became a cold case for nearly 30 years. The killer was discovered by a DNA database match from samples he was required to submit because of a conviction for a later rape in 1979 of another teenage girl. At the time of Quigley's murder, DNA technology was not sufficiently advanced for identifying suspects.

Through the years, Quigley's friends and classmates kept up the pressure on law enforcement to keep the case alive. In 2005, Detective Sergeant Kazem resubmitted evidence from the Quigley homicide investigation to the Santa Clara County Crime Laboratory for DNA analysis. On December 27, 2006, the Crime Lab informed Sergeant Kazem that a computer database search of DNA profiles of known offenders identified a Santa Clara resident, Richard Armand Archibeque, age 47, and a classmate of Quigley's, as the suspect. Later that day, Archibeque was arrested by detectives for the murder of Mary Elizabeth Quigley.

Archibeque was convicted of first degree murder in San Jose, California on March 2, 2009. He was scheduled for sentencing on March 27, 2009 under 1977 guidelines. He received 7 years to life.
