Police received a call from John Muir Medical Center in Concord at 6:21 p.m. reporting that a man was at the emergency room being treated for a gunshot wound.
The victim told officers that he had been fishing in Ellis Lake Park, located at Ellis Street and Clayton Road, when two people approached him and asked him where he was from, Carroll said.
When he refused to tell them, one of the suspects allegedly pulled out a handgun and fired one or two shots, striking the victim in the index finger, Carroll said.
The suspects fled afterward and the victim called a friend to get a ride to the hospital.
Both suspects were described as Hispanic males. One was said to be between 15 and 19 years old and about 5 feet 8 inches tall with a thin build. He was wearing a blue Dodgers cap, a football jersey and blue pants, Carroll said.
The second suspect was between 15 and 17 years old. He was about 5 feet 6 inches tall with a thin build. He was clean-shaven with slicked-back hair, and was wearing a long white T-shirt and dark pants.
Police searched for the suspects but didn't find them. They also searched the area where the shooting allegedly happened, but didn't find any evidence to corroborate the victim's account of the attack.
The victim's injuries were not considered life-threatening.
