WOODBURY - Police are reopening a cold case regarding the death of a 15-year-old rabbinical student from Staten Island.

Chaim Weiss was found dead by a dormitory supervisor at the Mesivta of Long Island, an Orthodox Jewish high school, in 1986.

At first, police said Weiss was bludgeoned to death, but the next day they said he died of multiple stab wounds to the head, neck and face.

No murder weapon was found and the case went cold more than 20 years ago.

Police are expected to hold a press conference with the family next week and raise the reward for information leading to an arrest.
