Police in San Francisco released surveillance images Tuesday of two "persons of interest" in a broad-daylight killing that occurred in May in the Marina District.

Kelly Freeman, 32, was shot on May 20 as he slept on the steps of a building on the 100 block of Alhambra Street, one block west of Marina Middle School, police said.

Investigators narrowed the time of the killing to between 6:15 a.m. and 11 a.m. Freeman's body was discovered at 11:30 a.m. by a resident in the building who called police.

Paramedics checked on the unresponsive man and soon discovered he was bleeding from a head wound. Freeman was pronounced dead at a hospital from a gunshot wound, officials said.

Homicide investigators discovered two men they called "persons of interest" in the slaying.

One man is wearing a maroon hoodie, jeans and black shoes. The other man is wearing a dark hoodie, black jacket, dark pants and dark gray Air Jordan-style high tops sneakers.

Anyone with information about the two men or the victim is asked to call San Francisco police at (415) 575-4444.
