OAKLAND -- A 15-year-old Stockton boy being prosecuted for his role in the fatal shooting of his 18-year-old friend in West Oakland earlier this month will be in juvenile court July 25 for a pretrial hearing.

The boy, whose name has not been released, is currently being prosecuted as a juvenile on one count of murder and two counts of attempted murder. Authorities are planning to petition the court to have the youth eventually tried as an adult.

Authorities said the youth was with Tommy Lacy III of Richmond when Lacy was killed about 7:20 p.m. July 6 in the 1600 block of 11th Street.

The boy surrendered to police the next day. He is being held at Juvenile Hall in San Leandro.

Because the investigation is ongoing, police would only say there was an exchange of gunfire between two groups that left Lacy dead. No one else was apparently injured.

Authorities are not releasing who shot Lacy.

But no matter who fired the fatal shot, under what is known as the provocative act doctrine, a crime participant can be charged with murder if someone is slain regardless of who does the killing, authorities said.
