Waterloo man convicted of killing ex-fiancee’s mom

A 34-year-old Iowa man faces life in prison after his convictions for shooting his former fiancee and killing her mother in May.

A Black Hawk County jury on Friday found Kevin Ambrose guilty of first-degree murder and attempted murder. Authorities say he shot former fiancee Marlene Buss, tried to shoot one of his own friends, Undray Reed, and fatally shot Buss’ mother, Kay Straw.

Buss had filed for a protection order against him on May 2.

Ambrose’s sentencing has not been scheduled. The first-degree murder conviction carries a mandatory life sentence without parole.
