Graves said the attacker reportedly was hallucinating and indicated he wanted to get off the bus. The man was taken to a hospital for a drug-induced condition, Graves said.
The passengers’ injuries included a broken sternum suffered by one person who helped restrain the attacker, said Officer Carrick Cook, another DPS spokesman.
Morris and a female companion got off the bus when it stopped after the attack, and they ran off into the desert, the DPS said. They returned about 30 minutes later.
When other passengers spotted the Morris returning, they started cursing at him and yelling “That’s the guy,” Ordinola said. Some threw rocks at him.
According to Ordinola, Morris’ companion tried to shield him before paramedics stepped in to stop people from going after Morris.
Morris was arrested at the scene and transported to a hospital. He will be booked into jail on suspicion of numerous counts of endangerment, assault and aggravated assault, the DPS said. Morris does not yet have an attorney.
Greyhound spokeswoman Alexandra Pedrini said the bus was carrying 41 passengers, plus the driver.
A relief bus was sent to the accident scene to take the nearly 20 uninjured passengers to Phoenix so they could continue to their final destinations, she said.
Ordinola, who had pain in her knees and a rib, was treated at a Phoenix hospital.
“I just want to go home,” she said.
