A 53-year-old man died Tuesday after he was struck in the back of the head with a two-by-four during an argument at a Queen park, police said.

The victim got into a quarrel with his attacker at Rufus King Park near 89th Ave. and 153rd St. in Jamaica about 8:40 a.m.

As the clash escalated, the victim was hit in the head with the two-by-four. His attacker ran off and has not been caught.

The victim was complaining of chest pains as medics rushed him to Jamaica Hospital, where he later died. The city Medical Examiner will conduct an autopsy to determine his cause of death.

A 14-year-old boy was shot on the other side of the same park Saturday afternoon. The teen was hospitalized in stable condition. His shooter is still being sought.
