OAKLAND -- A man fatally shot Monday in the city's 100th homicide of the year was identified by police Wednesday as 21-year-old Isiah Montouth.

Montouth was shot about 12:54 a.m. Monday as he was walking alone in the 5600 block of Hilton Street in the Melrose district. He died at 1:38 a.m. at Highland Hospital.

Police said Montouth had several addresses in Oakland, but none in the area where he was shot.

Officer Steven Bang said police still don't have a motive for the killing and no arrests have been made.

Police on Wednesday also identified the city's 99th homicide victim of 2012 as Demariae Coleman, 23, who was shot to death Oct. 10.

Coleman, of Oakland, was killed and his 24-year-old friend, who is also from Oakland, was wounded as they drove in the 1200 block of 47th Avenue about 9:35 p.m.

A 30-year-old man in another car was also wounded by the gunfire. The wounded men will recover, authorities said.

Police said Coleman and his friend were the intended targets of more than one gunmen and that the other man was an innocent victim.

No motive has been determined yet for the shooting and no arrests have been made, police said.
