The man cops found with fatal head wounds in the Haight district on Christmas Day had been struck with a skateboard, authorities said.
Dustin Tolboe, 28, allegedly bashed Donald Tanksley, 60, on the head with the skateboard, causing a severe skull-fracture, a witness told cops.
Police found Tanksley semiconscious at Haight Street and Masonic Avenue around 12:45 a.m. on Christmas Day, according to police.
Tolboe was arrested the day of the attack and charged with assault likely to produce great bodily injury and battery, according to the San Francisco District Attorney’s Office.
Tanksley, a San Francisco resident, died from his wounds three days later. Early last week, the San Francisco Medical Examiner classified the death as a homicide.
On Wednesday, the District Attorney’s Office began the process of charging Tolboe with murder. The case is scheduled to return to court Wednesday.
The homicide was the 50th of 2010 in San Francisco.
