Philadelphia police say two 15-year-old boys are being charged with murder in the shooting of a man walking his dog in what they say was a botched robbery.

Police said Thursday that one boy was under arrest and the second was being sought.

They are accused of killing 51-year-old James Stuhlman on March 12. Stuhlman was the owner of a suburban landscaping company who took nightly walks with his dog, a labradoodle named Molly.

Homicide Capt. James Clark says three boys were playing basketball when they decided to rob someone. Clark says it looks like the shooting occurred after a brief struggle.

Police say a 14-year-old boy has also been arrested on lesser charges and is cooperating with investigators.

The Associated Press generally does not identify juveniles charged with crimes.
