SAN FRANCISCO (AP) — While the San Francisco medical examiner has determined that the human remains found inside a suitcase abandoned on a downtown street belong to an unidentified light-skinned man, police have released a description of a suspect. Surveillance video shows the suspect is 5 foot 7 to 5 foot 8 and was wearing a pinstripe baseball hat, blue and orange jacket and light blue jeans, police said. Homicide investigators went door-to-door Thursday in a San Francisco neighborhood looking for surveillance camera video — or anything — that could be a clue to the case.
