More than two dozen guests at a theme-venue wedding celebration became ill, five of them seriously, and the incident became the focus of a criminal investigation Sunday, Riverside County authorities said.

Cal Fire/Riverside County Fire Department crews were sent to the venue just after 8 p.m. Saturday in the 31100 Block of San Timoteo Canyon Road, in an unincorporated area north of Moreno Valley. There is one wedding venue in the area of the address given by Cal Fire/Riverside County, Country Feels Ranch, which has a Redlands mailing address.

The agency reported five guests had what were considered major injuries, nine with moderate injuries and 12 with minor injuries. All of those conditions were at the time of the incident. Once the patients are transported, law enforcement and fire officials cannot provide updates on their health status because of privacy laws.

Some guests were transported by ambulance and a police bus to hospitals.

Five people taken from the scene were vomiting violently, Jody Hagemann of the fire department told City News Service.

There is no indication on the venue’s website that any food preparation is done there, which says wedding parties can provide their own vendors.

A woman who answered the phone there Sunday said there would be no comment on the incident, and an email to Country Feels Ranch was not answered by Sunday afternoon.

On its website, the venue says it can accommodate up to 500 guests and has an outdoor ceremony area, along with “bar and seating. As well as a huge indoor venue that can seat up to 170 guests, dance floor, DJ and more.” It rents for $4,500, the site says.

The Riverside County Department of Environmental Health also responded to the incident, but a spokeswoman Sunday said along with Cal Fire/Riverside County Fire that the Sheriff’s Department had taken over the investigation.

Investigator Armando Munoz said the department is looking into whether a crime was involved. He said Sunday afternoon there were no updates for the active investigation.

Hazardous materials had been initially ruled out, “however, the investigation continues,” Cal Fire/Riverside County said in an online statement.
