MARTINEZ -- A 23-year-old Pittsburg man has been charged with murder and attempted murder in connection with a Jan. 21 shooting that killed one teenage boy and wounded another.

Police said Julius Robert Short Jr. shot 16-year-old Pittsburg resident Steven Rosalez and Rosalez's 16-year-old friend on the 100 block of West Eighth Street in Pittsburg at about 7:45 p.m.

Prosecutors said the shooting occurred hours after a physical fight between Rosalez and Short. Investigators have not disclosed the nature of the dispute but did say the two knew each other.

Both victims were treated for their gunshot wounds at a hospital, where Rosalez died. Rosalez had been a Pittsburg High School student before entering an independent study program, his father said.

Short, who has a record of felony convictions in Contra Costa County, was arrested the day after the shooting and jailed on a probation hold until the Contra Costa County District Attorney's Office charged him late Friday with murder and attempted murder with use of a gun and being a felon in possession of a handgun.

He was arraigned in a Martinez courtroom on Monday morning but did not enter a plea and was referred to the Contra Costa County Public Defender's Office, said deputy district attorney Jill Henderson.

Short returns to court Thursday to enter a plea. He remained in County Jail on Tuesday in lieu of $1.5 million bail.
