Murder of Mary Quigley

Mary Elizabeth Quigley (February 28, 1960 – September 10, 1977) was an American murder victim whose death was a cold case for nearly 30 years before it was finally solved.

In the early daylight hours of the following morning, a groundskeeper noticed, at a distance, an object up against a fence that separated some apartments from the Santa Clara High School athletic field.

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, DOB 01/26/59, a classmate of Quigley's), as the suspect.

Archibeque was convicted of first degree murder in San Jose, California, on March 2 2009 and was sentenced to 7 years to life in prison.
