Airbnb CEO Brian Chesky said Saturday morning that the house rental service will ban "party houses" and crack down on "violent host- and guest behavior "a shooting at an unauthorized Halloween party in Orinda that left five non-Orinda residents dead.
People with knowledge of the transaction told the Associated Press that the woman who rented the house lied to the host and said she needed a place to keep family members away from the smoke. The host allegedly became suspicious of a night-time rental on Halloween, reminding the woman that no parties were allowed until they joined the rent.
After the shooting, Airbnb banned the woman from the platform. Chesky tweeted Saturday morning that Airbnb will take further action to stop unauthorized parties.
"First, we are manually expanding high-risk screening of the flag of our risk detection technology," tweeted Chesky. "Second, we create a dedicated & # 39; party house & # 39; rapid response team. Third, we take immediate action against users who violate these enhanced guest policies, including removal."
FULL COVER: No arrests following California Halloween shooting killed 5
Further details were not immediately available, and Chesky said a member of the Airbnb executive team will "launch a 10-day sprint" to review and accelerate the development and implementation of these new security initiatives. "
"We must do better, and so will we," Chesky tweeted. "This is unacceptable."
Five people were killed in the shooting.
The Contra Costa County Sheriff's Office originally identified the deceased as Tiyon Farley, 22, of Antioch; Omar Taylor, 24, of Pittsburg; Ramon Hill Jr., 23; and Javin County, 29. The county attorney's office identified a fifth victim, 19-year-old Oshiana Tompkins of Vallejo and Hercules, late Friday night, and said she died in a hospital.
The party in the four-bedroom house was apparently advertised on social media as a "ruling party for Airbnb." One participant told the Associated Press that he liked the music and watched people dance when he heard gunshots and people started running.
No arrests have been made.
