Three suspects have been arrested and charged in connection with the deaths of two people and the attempted murder of a third stemming from a wild shootout in Antioch in June in which a victim of a street robbery shot back, police said.

Miguel Gutierrez, 25, of Antioch and Julian Johnson, 26, of San Pablo were each charged by Contra Costa County prosecutors with murder, attempted murder, robbery and weapons violations. A third suspect, Teresa O’Sullivan, 44, of Antioch was charged with being an accessory to murder after the fact and weapons violations.

The chaotic gunbattle happened on the 1800 block of Cavallo Road shortly before 12:30 a.m. June 17, acting Antioch police Lt. Thomas Fuhrmann said Tuesday.

Police found Clydedale Hoskin Jr., 25, and a woman, Adrian Craig, 28, both of Antioch, dead at the scene and a 44-year-old Antioch woman suffering from gunshot wounds that were not life-threatening, Fuhrmann said.

Investigators determined that Hoskin, Gutierrez and Johnson had approached a group of people on the street and tried to rob them at gunpoint, police said.

During the confrontation, Hoskin opened fire, hitting the 44-year-old woman, Fuhrmann said.

But one of the victims was armed with a gun and fired back, striking and killing Hoskin, police said.

Gutierrez then pulled out a gun and opened fire, killing Craig, Fuhrmann said.

The suspects fled. Gutierrez was arrested July 9, and Johnson turned himself in on Friday. Both are being held without bail at County Jail in Martinez.

O’Sullivan, who allegedly helped the suspects after the slaying, was taken into custody Tuesday and is being held in lieu of $650,000 bail.
