LINCOLN PARK, Mich. – A Lincoln Park man has been charged after his girlfriend’s 3-year-old daughter shot herself with his gun, according to authorities. Skylar Johnston was playing with her 5- and 2-year old siblings around 1:40 p.m. Nov. 19 in a trailer located in the 3070 block of Dix Avenue in Lincoln Park, police said.

Johnston is charged with three counts of second-degree child abuse, which each carry maximum penalties of 10 years in prison. He is expected to be arraigned Wednesday at 25th District Court in Lincoln Park.
