'He hasn't stopped crying': Ex-college football star, 25, shoots dead his OWN MOTHER after mistaking her for an intruder at their Missouri home

A former football player shot dead his own mother after he mistook her for an intruder in their Missouri home.

Jaylen Johnson, 25, opened fire on his mother Monica McNichols-Johnson, 56, when she tried to enter the home in the St. Louis suburb of Olivette on Thursday night.

McNichols-Johnson died at the house even though Johnson's girlfriend tried to help her after she was shot. 

Johnson's attorney, William Goldstein, said his client immediately called 911 after he shot his mother, and he has been distraught ever since.

'He hasn´t stopped crying,' Goldstein said.

Last year, a teenager in Missouri was shot in the head and arm after mistakenly knocking on the wrong door.

Ralph Yarl, now 17, was shot in April after he went to the wrong address while going to collect his twin younger brothers from their friend's house in Kansas City, Missouri.

Yarl, who is black, knocked on the door of Andrew Lester, a white man, who shot him twice with a revolver. Lester was released on $200,000 bail and is awaiting trial after being charged with first-degree assault and armed criminal action.
