On Monday, the Contra Costa County District Attorney’s Office issued a statement saying they are not filing criminal charges at this time in the Orinda Halloween fatal shooting incident.

The statement was issued just before 5:30 pm.

“Today the District Attorney’s Office met with members of the Contra Costa County Office of the Sheriff to review the Orinda Halloween shooting incident. No criminal charges are being filed at this time against any individual. The investigation is ongoing. Anyone with information about the case should call the Sheriff’s Homicide Unit at 925-313-2600.”

According to Scott Alonso, public information officer with the DA’s office, they had a timeline of when they could file charges and were choosing not to file charges at this time.  He also confirmed that all five could get released, but said the Sheriffs Office could confirm if anyone has a hold on any of the five suspects.

An email to Contra Costa County Sheriff spokesperson Jimmy Lee has not yet been returned regarding the potential releases of the suspects.

The Monday announcement comes after last week, the Sheriffs Office announced they served Ramey arrest warrants and search warrants in several Bay Area counties this morning and arrested five suspects in connection with the Orinda shooting on October 31, 2019.

The five suspects are identified as:

  • 28-year-old Lebraun Tyree Wallace of the city of San Mateo. Wallace was arrested on the following charges: murder and conspiracy. He is being held without bail.
  • 20-year-old Jaquez Deshawn Sweeney of Marin City. Sweeney was arrested on the following charges: murder and conspiracy. He is being held without bail.
  • 20-year-old Jason D. Iles of Marin City. Iles was arrested on the following charges: murder and conspiracy. He is being held without bail.
  • 30-year-old Shamron Joshua Mitchell of Antioch. Mitchell was arrested on the following charges: murder and conspiracy. He is being held without bail.
  • 21-year-old Devin Isiah Williamson of Vallejo. He was arrested on the following charge: being an accessory. He is being held in lieu of $500,000 bail.

FRIDAY UPDATE — Sheriffs Office released mug shots Friday of the suspects

Sheriff David Livingston said Friday he wanted to provide the community an update on Thursdays press release where just after 7:00 am, they served search warrants at five locations.

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.

Livingston said they were still investigating motives in the shooting but said there were rival gangs in the altercation in the home and an attempt to steal property from one person.

“I went into the scene personally, in my 32-years of law enforcement, I have never seen a homicide scene like this ever, it was a blood bath inside the home,” said Livingston. “There were numbers and numbers of casings all over the floor, counter tops so it take a lot of analysis to be thorough.”

Livingston said when it came to security at the party, a person out front was supposed to be patting people down, however, they were observing drinking “Hennessy all night”.

On Thursday, the Sheriffs office said the arrest warrants were served in the cities of San Mateo, Marin City, Vallejo and Antioch.

The Contra Costa County Office of the Sheriff was assisted by the San Mateo Police Department, Antioch Police Department, Vallejo Police Department, Marin County Sheriff’s Office, U.S. Marshals Service, Bureau of Alcohol, Tobacco, Firearms and Explosives and Federal Bureau of Investigation.

Sheriff’s Office Detectives, assisted by multiple law enforcement agencies, have worked continuously on the investigation into the shooting that claimed five lives at a Halloween party.

The five suspects are identified as:

  • 28-year-old Lebraun Tyree Wallace of the city of San Mateo. Wallace was arrested on the following charges: murder and conspiracy. He is being held without bail.
  • 20-year-old Jaquez Deshawn Sweeney of Marin City. Sweeney was arrested on the following charges: murder and conspiracy. He is being held without bail.
  • 20-year-old Jason D. Iles of Marin City. Iles was arrested on the following charges: murder and conspiracy. He is being held without bail.
  • 30-year-old Shamron Joshua Mitchell of Antioch. Mitchell was arrested on the following charges: murder and conspiracy. He is being held without bail.
  • 21-year-old Devin Isiah Williamson of Vallejo. He was arrested on the following charge: being an accessory. He is being held in lieu of $500,000 bail.

“Extraordinary cooperation among multiple law enforcement agencies led to these arrests and a small measure of justice for the true victims,” said Contra Costa Sheriff David Livingston. “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 investigation into the shooting is ongoing. Anyone with any information is asked to contact the Sheriff’s Office Investigation Division at (925) 313-2600. For any tips, please email: [email protected] or call 866-846-3592 to leave an anonymous voice message.

  1. I’m stunned! How could this happen? Did those 5 people shot to death at that Halloween party shoot themselves? Which DA ordered this? From which county?

  2. 4 out of the 5 suspects were released around the 7pm timeframe on 11/18.

    The only suspect still is custody is – 28-year-old Lebraun Tyree Wallace of the city of San Mateo

  3. Our DA was is Diana Becton, Georg Soros founded her campaign. She’s worthless and lacking serious experience for the position…

  4. If any of these thugs do one wrong thing we need to recall DA. Sure they are good boys. Thugs were caring guns for self defense according to there Attorney. So I guess we should all carry guns by that thinking.

    • No matter what, we should ALL carry guns. An armed society is a polite society. By the way, the Second Amendment gives us that right.

  5. The IDIOT who represents DISTRICT 5 is the one who was pushing the incompetent DIANA BECTON to the position of county DA! I know one hell of a lot of people and NONE of them said they voted for her. I think she was just appointed.

  6. Becton is a racist piece of garbage! She enables her kind to victimize the rest of society. She needs to go!!

  7. That sounds kinda racist in itself.

    All this is , is just another reason we are headed to socialism if we don’t stop it now. Crime has been politicized. There is little fair justice anymore. Especially in California. Think hard when you vote. A popular name may be the worst choice. Do your homework or you will continue to see political justice not fair and equal justice.

    • Ma Becton sez: Git dem boyz out of jail NOW! Dey good boyz wid a brite footure! Maybe dey open a bakry in San Quentin.
