Authorities say a 55-year-old man who shot and wounded an Adams County sheriff's deputy has died of a self-inflicted gunshot wound.
The Adams County sheriff's office says Thomas Costigan of West Allis was pronounced dead Wednesday evening.
The sheriff's office says Costigan shot Deputy Todd Johnson Tuesday after Johnson and another deputy went to a house in the Town of Big Flats looking for Costigan's wife.
The Milwaukee Journal Sentinel reports West Allis police had notified Adams County authorities that the woman, who had a no-contact order against Costigan, was reported missing and that she might be with him.
Sheriff Sam Wollin says the suspect fired several shots at the deputies, wounding Johnson before shooting himself. He says the deputies did not return fire.
Johnson's condition was not released.
