Prosecutors have charged a man and a teenager with first-degree murder in the killing of an 8-year-old Detroit boy who was struck by a bullet as he was sleeping.

Twenty-eight-year-old Calvin Mosby and 17-year-old Devaunte Starks were arraigned Monday and jailed without bond. They also face attempted murder and firearms charges. It wasn't immediately known if they have lawyers.

Jakari Pearson was shot about 1:20 a.m. Wednesday at the Brewster Homes public housing project north of downtown Detroit. The bullet that hit him penetrated a wall at the residence.

Wayne County Prosecutor Kym Worthy says Mosby used to date Jakari's mother and went to the housing project to threaten her the previous day.

Michigan mandates life in prison without parole for first-degree murder. Starks is charged as an adult.
