Updates with more details from police, report of stabbing

One person was stabbed late Friday night, Oct. 28, and four others were shot early Saturday at a party at a Riverside shopping center, the Riverside police and fire departments said.

Their injuries were not life threatening, police said. A 19-year-old woman was initially believed to be in critical condition. The other victims’ ages were 19, 24 and unknown, the Fire Department said in a news release.

A crowd of 75-100 people had gathered in the 3500 block of Madison Street just west of the 91 Freeway, a Riverside police news release said.

UPDATE: Code Enforcement investigating venue where shooting, stabbing took place

Then just before midnight, Corona police officers were at Corona Regional Medical Center when a stabbing victim was dropped off by someone who then drove off. Police detained the vehicle’s occupants and learned that the victim was stabbed at the Madison party, the release said.

Riverside police then went to the Madison address about 1 a.m., the same time other officers were dispatched to a report of a loud party there, the release said. As officers approached, someone began shooting.

The officers were not targeted by the shooters, police Lt. Charles Payne said.

Officers found the four victims and detained the partygoers. Officers searched the business where the party was happening and found five hidden guns — three that were stolen — as well as what the release described as evidence related to the stabbing.

Riverside Police Lt. Mark Rossi said one person has been arrested on suspicion of possessing illegal narcotics. He said it was not yet known Saturday night whether that person was involved in the shooting.

No one, police Officer Ryan Railsback said, could describe the shooter or stabber.
