SF State business student Benjamin Herbert Floriani, 21, was fatally stabbed at a house party in Santa Rosa on Saturday morning. He was dead when emergency services arrived.

Santa Rosa police were notified approximately at 1:09 a.m. that someone had been stabbed in the 700 block of Blair Place in Santa Rosa.

“When emergency personnel arrived, a male was found deceased on the living floor,” said Sgt. Lisa Banayat of the Santa Rosa Police Department.

Between Saturday, December 15 and Monday, December 17 , five suspects have been arrested that were connected to the stabbing and three other stabbings at the same party. Alex Paul Hopper, 20, Matthew Timothy O’Day, 19 and Donald Bittner, 19, were booked on suspicion of murder. Noah H. Minuskin, 19 and Rory O’Day, 18 were booked with alleged accessory to the murder. All of the suspects are residents of Santa Rosa.

The autopsy report will not be available for several weeks, but preliminary reports say Floriani died of a stab wound to the heart.

The three other victims all survived their injuries according to Banayat.

Investigators are still looking for witnesses with information regarding the death of Floriani.
