A series of murders in San Francisco during the past week is pushing the city's homicide rate closer to the highest level in more than a decade.
Six people were murdered during the week, including a 22-year-old student at San Francisco State University who was found naked and stabbed to death in a vacant lot on Labor Day.
Later, the same day, a 26-year-old man was shot to death while walking home in the city's Visitacion Valley area.
Police say they believe he was mistakenly shot in retaliation for earlier gang violence.
The two murders have pushed the city's total for the year through Tuesday to 79.
That's just six homicides shy of the 85 recorded last year in San Francisco.
At this rate, the total for 2007 would approach 120 killings, which would be the most since 133 people were slain in 1993.
