Testimony:

It was the scariest night of Jason Prather’s life.

On Oct. 29, 2005, exactly one year to the day after a Halloween party fight, someone fired 15 bullets into his parents’ house, where Prather lived. The doors, walls and cars were pocked with bullet holes. No one was wounded.

About nine months after the shooting at Prather’s Santa Ana home, the same gun was used to kill Israel Maciel and wound his four friends in Costa Mesa, a weapons expert testified Wednesday.

Joshua Blount, 24, is accused of killing Costa Mesa resident Israel Maciel and wounding four others in a shooting in the 1300 block of West Baker Street in 2006. No shooting in Costa Mesa has had more victims, detective Dana Potts said.

Deputy Dist. Atty. Matt Murphy continued to portray Blount as a hard-core gangster to jurors Wednesday with witnesses testifying that Blount has a quick temper and holds a grudge.

On Oct. 29, 2004, Blount was with two friends at Prather’s Halloween party waiting for a keg to be tapped. Prather came up next to Blount, positioning himself to get the first cup of beer, Prather testified. After a short exchange of words, Blount punched Prather several times and pummeled him on the ground, Prather said.

Prather’s girlfriend owned the house. Her older brother, John Heesch, stepped in to defend him, Prather told the jury.

Heesch squared up to battle Blount but ended up fighting two of his friends as well, Heesch testified Wednesday. Within moments, more than a dozen men were involved in the fight, most of them defending Heesch and Prather, the men said. Blount got the worst of the beating, Heesch testified. Prosecutors said Blount left humiliated and beaten before police arrived.

Exactly one year after the fight, Heesch’s parents’ house was shot up. He told jurors he thought the bullets were meant for him and that Blount was the shooter. Heesch testified in the days following the shooting he feared for his life and would randomly see Blount and his friends around his home, he told jurors. Blount was never implicated in the shooting.

Murphy also aimed Wednesday to put Blount near the scene of Maciel’s drive-by killing.

An employee from the Sprint cellphone company testified calls from a phone registered to Blount show his phone was near the scene of Maciel’s slaying about 8 p.m. on Aug. 2, 2006, the time of the shooting.

Defense attorney Barry Bernstein pointed out Blount’s phone could have been up to 10 miles away from any cellphone towers Sprint uses to track its customers’ calls.

Witnesses testified Monday the driver of a silver Chevy Impala was the shooter. Some also testified that they saw Blount driving the car.

Bernstein maintains that the physical description witnesses gave of the shooter does not match Blount, but instead matches the description of his accused accomplice, Anthony Dispensa.

Dispensa is expected to testify today that Blount was driving the Impala and killed Maciel. Bernstein said he plans to portray Dispensa as a man out to save his own hide, and that he was actually the shooter.

Dispensa is also charged with murder related to the shooting.
