DETROIT -

Her teenaged sons are in the hospital, both shot by a worker claiming self-defense, but the boys' mother is now speaking out and saying the shooter's story doesn't add up.

The shooting happened last week when the utility worker told police two teens tried to rob him at gunpoint and he fought back. He opened fire on the teens hitting both of them.

The 16-year-old, Nicko Brown and his brother, 17-year-old Devante Brown, are in the hospital recovering from their wounds, and now their mother wants more answers. She told Local 4 the story isn't adding up.

"My 16-year-old, he's a smart kid, intelligent kid. He wasn't no ghetto gangster, no robber, never beat up a person or nothing like that," said the boys' mother, Selena Mitchell. "I never heard of my sons carrying no guns. I just don't understand."

Mitchell said she can't see her sons right now and nobody is giving her information on the case.

"I'm not understanding why I cannot get information on my children,. They're minors," said Mitchell.

The hospital told the boys' mother that even though they are minors, she may not have information on the kids because they are technically in police custody.

"I just can't understand it. Why were my babies shot up, and they're fighting for their lives in there and they're not telling me any updates? They're my sons," said Mitchell.

The teens are expected to be arraigned on charges Tuesday.

The utility worker who pulled the trigger has not been released.
