Tuan Nguyen, a 36-year-old San Franciscan, was found dead inside an apartment in the 600 block of Ellis Street. He was stabbed in the chest. The incident occurred a little before 1:30 a.m.

The suspect, 42-year-old Phuck Van Lee, whose relationship to Nguyen isn't quite clear yet, was kind enough to call the police to report the stabbing. Arriving officers "found him with blood on his hands and clothing," promptly arresting Lee soon thereafter.

One possible explanation? Booze. "They were sitting in the apartment drinking," said homicide Lt. Mike Stasko.
