A Queens teen was found shot to death in a Bay Shore park on Friday, the same day he was reported missing by his mother, Suffolk County police said.

Homicide detectives are investigating the death of Jonathan A. Graff, 17, of Queens, whose body was discovered about 4:15 p.m. Friday by a man walking a dog in the park.

The park is at Spur Drive South and Potter Boulevard, police said Saturday morning.

The body was taken to the Suffolk County medical examiner's office, where an autopsy will be performed, police said.

Det. Lt. Kevin Beyrer of Suffolk County Homicide Squad said Graff was last seen on Thursday afternoon in the vicinity of the Long Island Rail Road's Jamaica station.

"His mother reported him missing Friday," Beyrer said.

Beyrer declined to specify where in Queens Graff had lived or to provide information on a possible motive or witnesses.

"We're not going to discuss any evidence that we may or may not have found," he said.

Beyrer said police are awaiting autopsy results "to determine how many times he was shot."

Police ask anyone with information to call 800-220-TIPS or the Homicide Squad at 631-852-6392.
