ORINDA, Calif. _ Following a series of raids in Vallejo, Antioch, San Mateo and Marin City, authorities announced the arrest of five suspects Thursday in the Halloween shooting here that left five dead and several more injured.
In a news release announcing the arrests, the Contra Costa County sheriff's office also suggested that two of the five victims may have had a hand in the shooting. He did not say which ones.
The charges range from murder and conspiracy to accessory. Authorities have still not discussed details of the crime, nor exactly what role each person is alleged to have played.
The suspects have been identified as Lebraun Tyree Wallace, 28, of San Mateo; Jaquez Deshawn Sweeney, 20, of Marin City; Jason D. Iles, 20, of Marin City; Shamron Joshua Mitchell, 30, of Antioch; and Devin Isiah Williamson, 20, of Vallejo.
Williamson was arrested as an accessory, police said. The other four were arrested on suspicion of murder and conspiracy.
"Extraordinary cooperation among multiple law enforcement agencies led to these arrests and a small measure of justice for the true victims," Contra Costa Sheriff David Livingston said in a news release. "Additionally, evidence shows two of the deceased persons inside the house were themselves armed, which may have played a role in this tragedy. We look forward to providing more information in the coming days."
The raid in Marin occurred on the 200 block of Drake Avenue.
"We're very pleased to hear that there's movement in this case," Orinda Mayor Inga Miller said. She praised the multiple law enforcement agencies involved for, "investigating and bringing to justice the people involved in what happened on Halloween night."
The shooting occurred around 10:50 p.m. on Halloween, at 114 Lucille Way in Orinda. The house had been rented out on Airbnb, and was the site of a large party with more than 100 guests, authorities said.
Witnesses, mostly partygoers, in calls to police described a bloody multiple people lying in pools of blood inside the house. Other callers reported partygoers jumping off balconies and hiding in closets to escape gunfire, according to police call logs. Several of them described seeing a man shooting a Mac 10 or Mac 12-style firearm. Gunshot victims drove themselves to hospitals in Berkeley, Oakland and Walnut Creek.
Law enforcement officials said early on that the investigation included probes into gangs in San Francisco's Fillmore District and other parts of the Bay Area, including Marin City.
The victims have been identified as Tiyon Farley, 22, of Antioch; Omar Taylor, 24, of Pittsburg; Raymon Hill Jr., 23, of San Francisco/Oakland; Javlin County, 29, of Sausalito/Richmond; and Oshiana Tompkins, 19, of Vallejo/Hercules.
