The lawyer of a career criminal accused of mowing down an FDNY EMT insisted her client is “severely mentally ill” at his Friday arraignment — but the victim’s grieving coworkers weren’t buying it.

“He’s a criminal! He is not mentally ill!” one person shouted at the attorney outside Bronx Criminal Court.

“Bull s—t! Lock him up!” another coworker chimed in.

Jose Gonzalez, 25, who allegedly ran over veteran EMT Yadira Arroyo after taking her ambulance out for a joyride on Thursday night, was charged with two counts of first-degree murder, two counts of second-degree murder, manslaughter and robbery. He’s being held without bail.

Dozens of Arroyo’s colleagues showed up to the arraignment, where they became rowdy when Gonzalez’s lawyer spoke after the court appearance.

“He doesn’t deserve a voice!” they shouted at one point.

Israel Miranda, president of EMS Union Local 2507, said they are all “stunned” by Arroyo’s tragic death.

“People like this don’t need to be in the street,” he said of Gonzalez. “This court needs to do the right thing.” “This was no mistake. This wasn’t, ‘I didn’t see you.’ This was murder.”

Miranda added that Arroyo was working overtime when she was killed.

“That’s how much she loved her job that she picked up extra tours,” he said.

Bronx District Attorney Darcel D. Clark said Arroyo was “killed in such a senseless, horrific way.”

“We take for granted how our Emergency Medical Technicians and paramedics put themselves on the line every day to help New Yorkers,” she said in a statement. “Our prayers go out to her five children; may they find comfort in Yadira’s legacy of compassion and courage.”

Gonzalez is due back in court on March 22, 2017.
