Contra Costa County Sheriff David Livingston updated press outlets and the public Friday in the wake of Thursday’s arrests of five men wanted in connection with the murderous Halloween Night shooting at an Orinda home.
Livingston placed the blame for the murder of five people that night and in the hours following the shooting squarely on those arrested during a series of wake-up raids in Marin, San Mateo and Contra Costa counties Thursday.
The sheriff said several people were armed the night of the shooting, and that lingering bitterness between factions of rival gangs and the perceived theft of an unmentioned item that night likely triggered the gunplay – which left bodies strewn around the up-scale Airbnb “party house.”
Of the men arrested, Livingston said:
Wallace had prior convictions from DUI, driving on suspended license, receiving stolen property and illegal possession of an assault weapon.
Sweeney, who Livingston said was the suspect observed entering the residence with a firearm and when arrested had a loaded 9mm pistol. He has prior convictions for altercations, displaying a firearm and possession of a firearm.
Williamson, who was the promoter of this event, was arrested with charges of conspiracy, carrying a concealed weapon and vandalism.
Mitchell has prior convictions, per authorities: Assault with a deadly weapon, gang enhancements and other criminal threats. Livingston thanked Antioch Police who attempted to make the arrest where Mitchell attempted to flee out of a second-story back window before taken into custody in a backyard.
Livingston said based on evidence at the scene inside the residence, two of the deceased were also armed. The armed deceased person was identified as Ramon Hill Jr. who was a known associate with a gang in San Francisco. He had numerous convictions and on parole at the time of his death. He also identified Javin County as also being armed who had an extensive criminal history and also associated with a Marin City gang who had convictions for grand theft, robbery, assault, obstructing an officer and receiving stolen property and assault with a deadly weapon.
“Its important to note this investigation is still in its early stages. We wanted to make the arrest as soon as we were able with cooperating factual evidence to get them into custody,” said Livingston who says detectives are still seeking much technical information with federal partners and crime lab work. He also added there are still others they are seeking out.
Orinda Police Chief David Cook said this is an incident that has rocked the community and thanked all the state, local and federal partners for assisting the community.
Orinda Mayor Inga Miller thanked the Contra Costa County Sheriffs Office and assisting agencies for this investigating and bringing justice in this investigation.
