‘Something … set him off’: Mass stabbing at Orgon homeless shelter leaves 11 people injured

A mass stabbing at an Oregon homeless shelter sent 11 people to the hospital as officials said something set the suspect off before the attack.

Police were called to the Union Gospel Mission in Salem, about an hour south of Portland, just after 7 p.m. Sunday following reports of a stabbing, police said.

Victims suffered “varying types of injuries” in the attack, and their conditions were unknown Monday morning, Angela Hendrick of the Salem Police Department said in a statement.

Craig Smith, the executive director of the shelter, told NBC News the suspected attacker had just arrived at the facility the day before and was going to check in for a second night when he got into a fight.

“Something…set him off, and he evidently had a knife in his bag,” Smith said.

The altercation happened just as the man was about to turn over his belongings and check in. At least one staff member working at the check-in desk was injured, Smith said.

Bobby Epperly was on the second floor of the shelter when he said he saw the man screaming outside at traffic and holding a knife, the Salem Statesman Journal reported.

“It’s like a horror movie,” said Epperly, 48. He said he didn’t realize some people had already been stabbed inside the building until he went downstairs and saw “blood everywhere.”

Another witness, Malik Law, said he saw the man stab at least seven people.

“Everybody was basically trying to move out of his way,” Law said. “He started attacking them.”

Police have arrested the suspect but have not named the man.

The shelter, a faith-based organization, houses upwards of 150 homeless men and provides support services, food, clothing, case management and counseling.
