A screenshot from New Haven police body camera footage shows a grimacing Richard Cox being lifted into a wheelchair by NHPD officers. Cox, 36, was severely injured and likely paralyzed moments before en route to NHPD headquarters in a transport van. Cox's head slammed into the front interior wall of the van after the driver braked suddenly.

New Haven’s mayor and assistant police chief say they want to improve the police department after a man was severely injured while in police custody.

Richard “Randy” Cox was handcuffed and left unsecured in the back of a police van that lacked seatbelts. The officer driving says he stopped abruptly to avoid a car crash, injuring Cox. Video shows police later dragged Cox into a holding cell.

The five officers have since been placed on paid leave. Cox’s family said he’s paralyzed.

New Haven Mayor Justin Elicker said he saw “extreme callousness” on the part of the officers involved in the incident when he watched police body camera footage. Such a culture must change, he said.

“I also think that it’s important for us to foster a culture of intervention of officers having the tools and the support that they need to stop other officers when they have questions about following procedure,” Elicker told Connecticut Public Radio’s “Where We Live.”

New Haven Assistant Police Chief Karl Jacobson emphasized the need to train officers on the duty to intervene.

“Our leadership needs to push down to all our officers that it’s all right to question and say, ‘Hey, this doesn’t look right. Hey, why are we doing this?’” Jacobson said. “Just one of those officers saying something like that would have stopped the whole process, and they would have gotten him medical attention.”

Jacobson noted that in the past the department would address problem officers with discipline. Instead, he wants to pair up officers with model officers.

“We need to identify problems, fix them, have mentorship,” Jacobson said. “And if they’re not fixing them, then we need to get rid of these officers.”

He said that New Haven police are revisiting their policies and that one thing they’re looking into is an early warning system in internal affairs for officers with rudeness complaints. Jacobson added that this is not the way the department should be treating people.

“If officers treat people the way they treated Mr. Cox, we don’t want them to be police officers,” he stated.

Connecticut state police are investigating the case. Jacobson also notes that his department will respond “swiftly” in an internal affairs investigation.
