sfpd_crimescene.jpgSan Francisco police announced Tuesday that a suspect who killed a 36-year-old man inside a Hayes Valley apartment last month might have been cut during the stabbing spree, and are asking for the public’s help in making an identification.

Philip Dimartino, a former senior marketing manager with Archstone, was found Aug. 2 by a coworker in his apartment at 138 Hermann St. about two days after investigators believe he was killed, most likely on the evening of July 30, according to the San Francisco Police Department.

He was stabbed multiple times in the torso.

The motive for the killing is still being investigated and no arrests have been made, though police believe the killer might have been cut on the hand during the assault, a detail that could help in making an identification.

Anyone with information is urged to contact the San Francisco police homicide detail at (415) 553-1145. Information may also be given anonymously by calling the police tip line at (415) 575-4444 or by texting 847411 and typing “SFPD” before the tip.
