SAN FRANCICSO -- Even as there was another violent night on San Francisco's streets, local voters have narrowly defeated an anti-crime measure that would have pumped $10 million annually into police efforts to stem the city's homicide and violent crime rate.

Ironically, the violence began shortly after the polls closed. At 8:30 p.m., SF police were called to Garrison and Sunnydale where they found a 15-year-old boy sprawled on the ground with a serious head wound. He was taken to SF General and was in grave condition.

Just a few blocks away, police responded to discover a 33-year-old man's riddled body at 33 Blythdale. Police believe one of the weapons used in the murder was an AK-47. Authorities have no suspects in the two shooting, but were looking into whether the two drivebys were related.

About 30 minutes later, a fatal officer-involved shooting that left an unarmed man dead took place in a two-story apartment building near Lake Merced. Officers went to the Park Villa Apartments on 2 Garces -- which was supposed to be unoccupied -- and found two squatters inside. One man was arrested, but the other individual ran upstairs into a dark attic.

When the officers followed, authorities say the man took a shooting stance and appeared to be holding something. Wednesday, Chief Heather Fong said one of the officers felt her partner was in danger, so she opened fire.

"The partner officer who had the cylindrical object pointed at her felt something go past her ear. [She] felt that something had just gone by the side of her head. Believing it was a ricocheting bullet -- and having this individual facing her in a shooting stance with a cylindrical object pointed at her -- felt that her safety was in jeopardy, and she opened fire," Police Chief Fong explained.

The name of the man who was shot has not yet been released.

Meanwhile, at the ballot box Measure A, which proposed altering the city's charter to allocate an additional $10 million a year for the next three years to homicide and violence prevention services, appears to have failed by a narrow margin. Unofficial results show 50.52 percent voters against the measure and 49.48 percent of voters in favor.

In other election news, Measure B, which would require landlords who are selling buildings with two or more residential units to tell all potential buyers in writing whether or not any tenants evicted from the building are elderly or disabled, appears to have passed. In unofficial results Measure B was supported by 52.62 percent of voters and opposed by 47.38 percent of voters.

Measure C, which would have changed the designation of the city's representatives on the board of directors of the Transbay Joint Powers Authority did poorly, with 71.14 percent of voters opposing the measure and 28.86 percent supporting it.

The measure would have designated three elected officials to represent San Francisco on the TJPA board - the Mayor of San Francisco, the member of the board of supervisors representing District 6, where the Transbay Transit Center will be located, and the member of the board of supervisors who is on the Metropolitan Transportation Commission.

Measure D also did poorly, with 72.98 percent of votes against it and 27.02 percent of votes in favor.

The measure proposed amending the city's planning code to create the "Laguna Honda Hospital Special Use District" where the Laguna Honda Hospital is located.

Changes introduced by the measure would have allowed both publicly and privately owned residential health care facilities in districts designated as public.

Measure D would also have allowed the city's zoning administrator to enforce limitations that included restricting the admission of patients with certain psychiatric or behavioral conditions on Laguna Honda Hospital and other residential health care facilities located in any public district in San Francisco.
