A Michigan man shot and killed his twin brother and himself and wounded his father in a series of shootings inside a home and may have also killed the family dog, police said.

Authorities in Troy, 25 miles north of Detroit, said the unidentified 23-year-old committed the crimes Monday morning but no motive has been disclosed. Officers received a call around 12:25 a.m. from a 62-year-old man who said he had been shot by his son inside a home.

He remains in critical but stable condition.

A woman, 64, was at the home when shots rang out but was unharmed, police said. The suspect was found in the basement dead from a self-inflicted gunshot wound, authorities said.
