Pierre Oliver, 43, was found unconscious after a severe beating at Holly Park on Highland Avenue in San Francisco on October 5, 2008. He spent several months in critical condition and died of his injuries on June 8, 2009.

San Francisco Police Department homicide inspectors Brian Delahunty, John Cagney, and David Martinovich have worked the investigation, and the city has offered a $25,000 reward for information that leads to identification, arrest, and conviction of the person or persons responsible. The assault and its fatal outcome remain unsolved, one of several open homicides from that period in the city.

Anyone with information about Oliver, his movements that day, or the attack is asked to contact investigators.
