Mader was sacked soon after in what he said was "a flawed effort to buttress the other officer's use of deadly force", according to the wrongful termination lawsuit he filed past year against Weirton in West Virginia federal court.
Mader told CNN previous year that Williams was "visibly choked up" and told Mader to shoot him. When Stephen asked him to show his hands, he complied, revealing a gun. In part, the lawsuit argued that terminating a police officer for failing to shoot a person the officer deemed no threat to the officer or others was in violation of West Virginia public policy.
He died at the scene. Investigators later learned that Williams' gun was not loaded.
Mader, who is white, didn't think Williams was a threat to anyone and the officer tried to talk to him.
While Mader was negotiating with Williams, two other officers arrived on the scene.
GoFundMeA former West Virginia police officer who was sacked after not shooting a suicidal man wielding an unloaded gun has reached a settlement in a wrongful termination lawsuit that has drawn national headlines. "No police officer should ever lose their job - or have their name dragged through the mud - for choosing to talk to, rather than shoot a fellow citizen", Mader's attorney Timothy O'Brien said after the settlement. Mader reportedly didn't file a police report, collected no evidence, and the body was sent to a funeral home.
According to the lawsuit, Mader responded to a call from Williams's girlfriend that he was threatening to hurt himself with a knife. Mader maintains his firing was unjustified. "Just shoot me." Two other officers later arrived, and Williams raised his gun and was shot in the head by another cop.
Travis Blosser, Weirton's city manager, told The Washington Post the city is "pleased to see that the matter is over with".
Officials in Weirton, an Ohio River community of 19,000 residents 36 miles west of Pittsburgh, had said Mader was sacked eight weeks after the shooting for conduct unbecoming of an officer in three separate incidents.
A month later, reports state, Mader responded to a call about a cardiac arrest, and found a woman dead on a stairway. "Basically, no police officer ought to ever feel compelled to end an existence superfluously to spare his profession".
According to published reports, in March 2016, Mader was issued a verbal warning for placing a parking ticket inside a vehicle without having a search warrant and cursing at the owner's wife.
The Guardian reported that Mader also got a pledge from the Weirton Police Department that it wouldn't try to prevent him from obtaining a new job elsewhere in law enforcement. A tumultuous direct charge against the proprietor was later dropped.
Around the same time, a State Police investigation ruled the shooting had been justified.
Mader was sworn in as a probationary police officer in Weirton in July 2015.
That officer was later cleared of any wrongdoing.
