A 14-year-old Detroit boy pleaded guilty Monday to shooting and killing his mom Feb. 27.

Joshua Smith pleaded guilty to second degree murder and a felony firearm charge in connection to the murder of his mother, 36-year-old Tamiko Robinson.

Robinson was sleeping on a couch at about 3 a.m. when she was shot.

Robinson’s fiancé, Chika Lewis, and her 5-year-old daughter were also in the house at the time of the shooting. Lewis said he grabbed his 5-year-old daughter, broke out a kitchen window and ran for help to a neighbor's house.

The teen was arrested by police a short time later after fleeing in his mother’s car.

Smith is expected to be sentenced to 25 to 50 years on the murder charge and a mandatory 2-year sentence for using a gun. He is scheduled to be back in court Oct. 26.
