Police in upstate New York say the son of a Greenburgh rabbi who died Thursday had been issued a summons for smoking marijuana less than an hour before he was found unconscious and fatally injured.

Jonah Dreskin, of Ardsley, died soon after he was found on an access road that runs beneath dorms on the campus of the University at Buffalo. Authorities are still unsure how he died, though they believe he could have jumped or fallen from a seventh-floor dorm window or been hit by a car.

Police say there's no indication that the marijuana summons had anything to do with his death. Typically, students who receive summonses are required to attend disciplinary hearings and perform community service or take drug education courses.

Authorities are waiting for toxicology tests to come back on any drugs or alcohol in Dreskin's system. They say the test results could take up to two weeks.

Officials at the synagogue where Dreskin?s father is a rabbi issued a statement, saying, "It's a tragic and premature loss of a loving and brilliant young man. We're putting all our energy into mourning his passing and consoling our Rabbi and his family."
