Man with shotgun storms into home searching for ex-girlfriend. But homeowner is armed, too — and gives intruder lethal greeting.

Detroit police said a male homeowner was outside with his family and children when he heard a disruption inside his house just after 9:30 p.m. Tuesday — and encountered a man with a shotgun, WXYZ-TV reported.

But police said the homeowner also had a gun and fatally shot the 20-year-old suspect, the station said.

Witnesses said the intruder was the ex-boyfriend of a woman who was inside the home, WJBK-TV reported. "He [was] out to kill. He didn't care," a female resident who didn't want to be identified told WJBK, which added the suspect allegedly forced his way into the home.

"He pushed my granddaughter who answered the door," the anonymous female added to WJBK. "He literally shoved her." This woman who spoke to the station said she doesn't know the suspect's name but that he was her daughter's ex-boyfriend.
