From the Office of the Sheriff:

Law enforcement agencies 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 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: tips@so.cccounty.us or call 866-846-3592 to leave an anonymous voice message.


  1. So everyone is being sued, including the city of Orinda. Wonderful. Once again, if Orinda had banned Airbnb in 2017. Thank you to all the people on other news sites that expressed your compassion towards the residents on Lucille Way (the real victims) and your disdain towards the decision of the Orinda City Council.

    Keep this inner-city lifestyle in the inner-city where it belongs.

    This could easily happen again – anywhere. Why pay what we pay to be homeowners in Orinda when we could easily live on the south side of Chicago. I guess we now “stay in Orinda.” We have street cred. Oh, happy day.

    • Referring to the “residents of Lucille Way” as “the real victims” marginalizes the five young souls who were slaughtered and a half dozen others who endured unthinkable physical trauma. Such a cruel characterization implies they are not “real” victims — and offends the most basic notion of human decency.

      The neighbors were certainly frightened and obviously inconvenienced but, thankfully, none were physically harmed.

      As a former resident of Lucille Way (we lived on the adjacent property some years ago), I am offended, disappointed and ashamed to share a community with anyone who feels comfortable publicly expressing such callous indifference.

      Our former neighbors on Lucille were all gracious, kind people who would be appalled by such depraved equivalency.

      • And the Orinda City Council has “callous indifference” towards the safety of the residents of Orinda. And the party goers have “callous indifference” towards the residents of Orinda as well.

        Once again, keep this gang-related inner city life-style where it belongs. In the inner-city.

        There are residents of Orinda who feel stronger than I do. People are not mincing their words. And neither do I.

        I hope they keep this in mind during the next election.

        And any Airbnb gone bad, the REAL and INNOCENT victims ARE the neighbors. Nobody wants this in their neighborhood. Our neighbors actually think we’re okay with Airbnb too. It’s called being tactful, and online I’ll tell you how I really feel.

        So now you’ve “lived on Lucille too?” How convenient for your alleged argument.

    • Orinda is the Bay Area’s per capita murder capital this year. Perhaps the self righteous, indignant residents whose insensitive world view and condescending rhetoric reflects so poorly on our community will leave.

  2. No one will say it but I’m afraid it boils down to a culture where violence is viewed as an accepted method of dealing with an old argument or ongoing feud. there were lots of parties that night, some of them at airbb locations. This could have happened at any one of them.

    • Valid. There are barbaric savages in every community who resort to violence. It’s fortuitously rare in our little enclave, but even our little princes and princesses succumb to their darker urges.

      (Remember in 1984 when a Miramonte girl filleted her classmate over cheerleading envy? That’s part of the thug culture too.)

      • Good grief, you’re seriously bringing up some 35-yr-old CHEERLEADER crime as “thug culture”, as if it’s even in the same GALAXY as the true thug culture which descended upon Orinda Halloween night? Oh the self-righteous virtue-signaling is just so delicious, more please.

  3. How many people were armed at that party? Add a little alcohol and stir in some drugs and boom boom boom….. crazy.

  4. Wow to all of this, how incredibly sad. Plenty of sympathy and blame to spread around, but the fantasy of affluence buying some insulation from Bad Things is clearly exposed. Cities and towns all over were slow to understand and figure out how to regulate these short term rentals; scrambling now to fix it after the fact. In high rise condos in cities, as many as 80% of units are short term rentals, leaving actual residents living in ghost towers that become hotels with no real oversight within the building. Neighborhoods in popular recreation areas (Lake Tahoe) were being hollowed out, long time families suddenly surrounded by rowdy rentals, and now regulations banning rentals in some areas away from the main business corridors have been voted in. In areas with homeowner associations usually have a better handle enacting limits and enforcing them, and in some places (Marin County) there are new county rules for regulation and enforcement in unincorporated Marin (Stinson, Bolinas, Tomales, Dillon Beach, Marshall, etc.) collection of Transient Occupancy Tax, etc.

    I know several owners of vacation rentals in our coastal town who have skilled managers in town, keep the rental more low key than Big Party Places that become That Problem Rental. We often have repeat visitors who are respectful and welcome, but sadly, some visitors leave their brains and manners at home, arriving loud and proud and treating our neighborhood like a resort. We at least have a mechanism in place with our HOA for complaints, a fine schedule, hearings before the Board of Directors, etc. but it gets old having to police houses that aren’t a home, rather than someone’s business model and profit center. I have feared for years we could have a deadly situation similar to the one in Orinda…

  5. Not to burst bubbles here but airbnb is only one of many platforms this property was listed on. Hell I bet this owner has had it on Craigs list at some point. The biggest negative I have found living in Lamorinda. Is the perception that its some kind of wonder land free of crime and filtered at the door to keep criminals from passing through town. Thats one of the biggest negatives given we end up with residents who truly believe they can escape the cruel reality of society here. You know do things like leave their purse on a car seat in a unlocked car and have no repercussions. Leave laptops in cars with no repercussions.

    Ignore that their HS kid is involved in stuff that was enabled by the parents wealth.

    I’m curious if the Vallejo Airbnb House party on the same night was part of a bigger for profit clubing/party scheme put on by the same people that booked the Orinda party.

    The owner of the Vallejo Airbnb has video footage of party goers discussing the Orinda shooting at the same time it happened. Meaning this party circuit ie group is far bigger and more connected than just the Orinda event.

    • Leaving a purse or a laptop in your unlocked car has nothing to do with Lamorinda and everything to do with lack of common sense. People do that everywhere, including high crime areas. It’s the mindset of “it will never happen to me.”

        • CalDude – we take your point but we would broaden the region of affliction beyond Lamorinda. We certainly have our moments, but we don’t have a monopoly on the condition.

          • Nope we don’t. But its an opportunity to create a change in Lamorinda. Its not magically protected from the real world.
