Jessica Cooper hand-delivered a signed court order to the Lincoln Park Police Department in Michigan in August 2022.

The document would have allowed police to transport her cousin, Shane Cousins, 33, to a mental health facility involuntarily for an evaluation — had the police department followed through.

Instead, Cousins’ mental health continued to spiral; his delusions and paranoia intensified, and on Jan. 24, Michigan State Police troopers killed him after he fired a gun at a police helicopter flying above his brother’s Detroit home.

In the months leading to his death, Cousins thought planes and helicopters were the government’s way of spying on him — or, on some days, a way of dropping cannabis seeds from the air as a means of confiscating his grandmother’s land in Tennessee. He’d shoot at aircraft “to scare them off,” his family told the Detroit Free Press, a member of the USA TODAY Network.

He also thought the government was trying to kill him. He walked around his house and yard firing guns. He threw screws in the middle of the street. He thought he was the leader of Ukraine. He thought TVs and radios were sending him subliminal messages. He thought family members were human traffickers, his grandmother part of a cult.

Previous attempts by Cousins’ family to help him get a formal diagnosis and treatment failed. And after Cousins barricaded himself in his home with guns and had a standoff with Lincoln Park police on Aug. 7, 2022, the Cooper-Cousins family desperately sought a court order to have him evaluated involuntarily.

That’s what Lincoln Park Police Lt. Patrick Culter told them to do, according to a police report of the incident.

On Aug. 17, 2022, a Wayne County probate judge issued the order.

But when Cooper hand-delivered the order to the police department, Cooper said, Culter told her she and her family were harassing Cousins. He wasn’t convinced Cousins was mentally ill, she said.

Still, Cooper said her family devised a plan with Lincoln Park police to get Cousins out of his house to a local McDonald’s, away from his guns, so he could be apprehended. Officers never showed up, she said.

Reached by phone for comment, Culter said he wasn’t authorized to speak to the news media. Lincoln Park Police Chief Scott Lavis, who took leadership of the department this month following Chief Ray Watters’ retirement, said he was looking into the matter.
