The Medical Examiner's office moments ago identified the man murdered Tuesday morning in Buena Vista Park to SF Weekly: Joseph Swim, a 33-year-old man with no fixed address.

Swim was purportedly drinking in the park with a pair of companions including 30-year-old Michael Little. When Little and Swim had words about a woman, according to the San Francisco Police Department, tempers flared and Little allegedly stabbed Swim.
