A Detroit man has pleaded guilty to second-degree murder after his 9-year-old son found a shotgun at home and fatally shot himself.

The Wayne County prosecutor's office says 45-year-old Christopher Duran Head also pleaded guilty on Tuesday to involuntary manslaughter, child abuse and weapons offenses.

Daylen Makhai Head was fatally shot in the head Nov. 9 on the city's west side. Police have said he was handling a loaded shotgun that wasn't secured.

Christopher Head and another child also were at the home.

The father faces up to life in prison when he is sentenced April 27 by Judge Dana Hathaway.
