Modern-day fingerprint analysis technology and a San Diego police intern helped solve a 37-year-old murder. Gerald Metcalf, 60, was arrested yesterday in Texas on suspicion of killing Gerald Jackson, 27, in Pacific Beach.

According to San Diego police, Jackson, a U.S. Postal Service carrier and part-time doorman at the Barbary Coast was found dead by his friends in his apartment after he hadn’t turned up to work for a number of days.

Officers determined Jackson had been stabbed to death sometime after Dec. 28 and his house had been tossed. According to homicide officer Lt. Terry McManus, Jackson’s Ford Torino was found days later in Mexicali, Mexico, and some of his property had been pawned by someone assuming his identification.

The case went unsolved until this past January. An intern assigned to the homicide unit’s cold case team examined the evidence, and investigators, using current fingerprint analysis technology, matched a print from the crime scene to Metcalf. McManus said the case was reopened with assistance from the San Diego and Henderson County, Texas, District Attorney’s Offices.

Texas Department of Public Safety officers arrested Metcalf before noon and he is currently being held in Henderson County Jail awaiting extradition to San Diego, McManus said.
