Wednesday afternoon, the Contra Costa County Sheriff’s Office identified the suspects as Domico Dones of Martinez and Frederick Johnson of Vallejo, both 29.
Authorities confirmed the Contra Costa County Sheriff’s Office and the ATF served Ramey arrest warrants and search warrants in multiple locations, including Martinez and Vallejo at 7 a.m. Thursday.
Both suspects were booked on charges related to the Orinda shooting. Dones faces charges of being a felon in possession of a firearm and a felon in possession of ammunition. Johnson faces charges of being a felon in possession of a firearm, a felon in possession of ammunition and child endangerment.
The suspects were booked into the Martinez Detention Facility shortly before 1 p.m. Thursday. Dones is being held in lieu of $300,000 bail, while Johnson is being held in lieu of $75,000 bail.
While executing the warrants, ATF agents seized a gun that was linked through ballistics testing to multiple other shootings in the Bay Area, Corneiro said.
Multiple people were arrested in connection with the shooting last Thursday, but most of the suspects were released when Contra Costa County prosecutors decided not to file charges on Monday.
According to the sheriff’s office, prosecutors wanted more investigation before bringing criminal charges.
The San Francisco division of the Bureau of Alcohol, Tobacco, Firearms and Explosives posted photos and made the announcement via its Twitter account Thursday evening.

Pictures show ATF personnel in heavily armed vehicles during a raid made as the agency assisted Contra Costa County authorities in the investigation into the Orinda shooting.
The agency initially did not specify if the photos were from the raids that took place last Thursday during the initial arrests or if a more recent raid with new arrests had taken place.
However, late Friday morning, the Contra Costa Sheriff’s office confirmed that additional arrests had been made in connection with the Orinda shooting, but provided no additional details.
Some additional arrests have been made in the Orinda shooting case. We will issue a press release later today.

The sheriff’s office has been investigating the Oct. 31 shooting with the assistance of federal agents. Gunfire broke out in a 4,000-square-foot home at 114 Lucille Way shortly before 11 p.m. during a large Halloween party.
The home had been booked for the party on Airbnb. Police said when they arrived, more than 100 people were trying to flee the premises.
Three people were already dead. Two others died after they were taken to a hospital. Three more were taken to a hospital with injuries.
Police said after the shooting that they were unsure how many people might have been injured and taken themselves to a hospital. ATF officials said Thursday that a total of nine people had been wounded in addition to the five who died.
Sheriff’s officials made arrests of five people on Nov. 14. But on Monday, the district attorney’s office announced that it had declined to file charges against any of them.
The ATF also announced a $20,000 reward for information leading to arrests in the case. Anyone with information has been asked to call (888) ATF-TIPS.MORE NEWS: Derek Chauvin Trial: South Bay Activists Relieved By Guilty Verdict
