Fifty-year-old Angelo Nelson was found dead in the stairwell of his apartment complex Monday morning. 

Police say Nelson allegedly got into an argument with his downstairs neighbor, 31-year-old Dominic Nosacek. 

Nelson's mother, Patricia Donald, said she talked with residents in the building who said they did not hear yelling - just one shot.

"They said it was quiet, so they never heard an argument, they just said there was a shot," Donald explained.

According to the search warrant, Nosacek drove to a government building a few blocks away from his apartment where he told guards that he shot his neighbor.

"That ugly miserable son of a b****," said Donald. "That man took my baby's life."

Nosacek told security guards the rifle he used to shoot nelson was in his living room.

When police searched his apartment, they found over 100 cartridges of ammunition and multiple magazines.

heard the shot, Donald said other residents feared for their lives.

"He thought that man might come do something to him too. He said that man was evil. He said he was coming down the stairs at the wrong time," said Donald.

In the criminal complaint, Nosacek stated that he was diagnosed with "psychosis" and "depression."

Earlier the day of the shooting, Nosacek said that people were "shaking him" and threatening him. When he left his apartment, with his gun, he says Nelson was "waiting for him." Nelson then ran and Nosacek shot him. 

When asked if he intended to kill him, Nosacek told officers, "yeah because they are militia" and "terrorists."

Nosacek told police that he didn't see anything in Nelson's hand and there was no argument leading to the shooting. 

Court records show Nosacek's prior criminal history of multiple counts of battery and domestic abuse and that he wasn't legally allowed to possess firearms at the time of the shooting. 

"This is one that's going to hurt a lot of people that know him," said Donald. "The city of Milwaukee will mourn him for a long time." 

Nosacek has been charged with one count of first-degree intentional homicide and one count of bail jumping.
