Riverside County Sheriff Chad Bianco said he is calling in federal partners to assist in the investigation of a shooting that left seven people dead in Aguanga in the early morning hours Monday, September 7.

Seven people died after suffering from gunshot wounds at a suspected illegal marijuana grow operation, officials from the Riverside County Sheriff’s Department said.

In a press conference Tuesday, September 8, in Riverside, Bianco said more than 20 people lived at the the property, which had multiple residences and makeshift buildings, marijuana cultivation, harvesting and processing areas and several vehicles with out-of-state registrations. 

Deputies also discovered a BHO or butane honey oil lab. 

According to the Department of Justice, butane honey or hash oil labs are highly dangerous facilities used to extract THC from marijuana, using butane – a highly flammable gas, posing a fire and explosion risk to nearby residences.

“During the investigation of this incident, it was determined that this residence was an obvious large scale illegal marijuana cultivation and processing center,” Bianco said. “We believe at this time that there were multiple suspects.”

Investigators seized more than 1,000 pounds of marijuana and several hundred live marijuana plants. Street value was estimated at between one and five million dollars, he said.

“We have asked for help from our federal partners,” Bianco stated. “We are actively working with them for any leads we may come up with and evidence processing they can help us with.

“It was a large scale operation, obviously illegal, like almost every grow in our mountain communities,” Bianco said. “This was not a small operation – this was a very organized crime type of an operation.”

We believe it could have possibly been a rental property, the sheriff added.

“So far in 2020, he said, this is our eighth call of a homicide with 14 victims, dealing strictly with marijuana,” Bianco said. “Marijuana is not a victimless crime. We at the sheriff’s department are enforcing these illegal marijuana grows with our search warrents and confiscating illegal marijuana and taking these properties if we can.”

Bianco promised increased enforcement activities.

The victims in the shooting were located around or in one of the dwellings located on the large property.

All seven victims and witnesses were Laotian, Bianco said.

Laotian involvement in illegal marijuana harvesting has grown over the last decade in California.

“This is not going to be an easy investigation. It will span multiple states, which is why we have reached out and included our federal partners to assist us,” Bianco said.

Deputies responded to a 911 call of an assault with a deadly weapon at a residence located on the 45000 block of Highway 371 early Monday morning, where they discovered the shooting victims. Six died at the scene as a result of their injuries, and one woman succumbed to her wounds at a nearby hospital.

Deputies searched the surrounding area, but the suspect or suspects remain outstanding.

Investigators from the Riverside County Sheriff’s Department Central Homicide Unit and Hemet Station responded and assumed the investigation.

Sheriff’s Department officials said the shooting appeared to be an isolated incident, and there is no threat to the general public.

The Riverside County Sheriff’s Department urges anyone with information regarding the incident to contact Central Homicide Investigator Paz at 951-955-2777.

The shooting remains under investigation.
