A 14-year-old boy allegedly shot his mother to death while she was sleeping and her fiancé and 5-year-old daughter slept in the next room in a house on Detroit's east side Monday night.

Tamiko Robinson, 36, died after allegedly being shot by her son several times at close range, according to Fox 2. The station reports the boy is in custody after allegedly attempting to flee in his mother's car.

The boy's uncle and Robinson's brother, Leshaun Roberts, told the Detroit Free Press Robinson was sleeping in the living room and her fiancé was asleep in an adjacent room with the couple's five-year-old daughter. According to FOX 2, the fiancé's name is Chiko Lewis.

The Free Press reports the 14-year-old used a gun owned by Lewis in the shooting. As for motive, Roberts told the paper the boy's mother earlier had refused to let him hang out with his friends.

Detroit Police Chief Ralph L. Godbee Jr. and Mayor Dave Bing held a press conference Monday afternoon to address Robinson's shooting and other recent gun violence involving minors, including the early Monday morning shooting of a 6-year-old boy in an attempted carjacking. The boy is still in critical condition. Police say the two suspects in custody for the child's shooting are also teenage boys.

Bing asked Detroiters not to stand idly by while children become victims of crime. But at the same time, he demanded parents take more responsibility for their children's actions.

"You can't expect the police to be in every home, on every corner, responding to things that we as parents and adults ought to be responsible for," he said. "Let's let these young people know that we care about them but at the same time, we aren't not going to allow them to create havoc. You have to start discipline ... when they come out of the womb."

Three children have been shot in Detroit in the past month. Two have died from their wounds, one a 9-month-old infant, the other a 12-year-old girl.

A Detroit Police Department spokesman declined to comment further on the shootings Monday afternoon.
