After responding to a report of a domestic incident on May 6 in Weirton, W.Va., then-Weirton police officer Stephen Mader found himself confronting an armed man.

Immediately, the training he had undergone as a Marine to look at “the whole person” in deciding if someone was a terrorist, as well as his situational police academy training, kicked in and he did not shoot.

“I saw then he had a gun, but it was not pointed at me,” Mr. Mader recalled, noting the silver handgun was in the man’s right hand, hanging at his side and pointed at the ground.

Mr. Mader, who was standing behind Mr. Williams’ car parked on the street, said he then “began to use my calm voice.”

“I told him, ‘Put down the gun,’ and he’s like, ‘Just shoot me.’ And I told him, ‘I’m not going to shoot you brother.’ Then he starts flicking his wrist to get me to react to it.

“I thought I was going to be able to talk to him and deescalate it. I knew it was a suicide-by-cop” situation.
