Police said a 23-year-old man was holding a gun in each hand, and threatening his mother and officers at the time he was shot.

He was a good man who served this country,” said the mother of Derrick Williams, who was killed in the police shootout Monday in a NoMa apartment building.

The victim, the police said, was carrying a knife. The shooting, which occurred after a five-second encounter, was under investigation.

A 40-year-old man was killed in a police-involved shooting Wednesday morning in Northwest Indiana, the Lake County sheriff and coroner's office said.

The 23-year-old man reported dead after being shot at his home Saturday was shot by an officer responding to a domestic abuse call, according to Gary police.
