Chicago police say a 15-year-old boy was found fatally shot in a backyard about four blocks from President Barack Obama’s home on the city’s South Side.

Cornelius German had been shot in the back and was found unresponsive at about 9:40 p.m. Monday in the 700 block of E. 50th Place.

Police Department spokesman John Mirabelli says German was a gang member but that the motive for the shooting was not yet certain.

German was pronounced dead at the scene shortly after he was found.

Obama’s home is just blocks away in the Kenwood neighborhood.

Mirabelli says no one is in custody as of Tuesday morning.
