Rabbi Dovid Winiarz, the self-proclaimed “Facebuker Rebbe” known for his outreach efforts over Facebook, was killed in a car accident in Maryland.

Winiarz, 49, of New York, was a passenger on Jan. 18 in a vehicle that lost control in the icy conditions and struck another car. He was on his way to a Jewish outreach convention in Baltimore.

More than 400 people attended his funeral Jan. 19 on Staten Island. Winiarz was the father of 10 children.

Winiarz was president of Survival Through Education Inc., which calls on Jews to discover their faith and reach out to unaffiliated Jews, and served as the rabbi at the Multi-Faith Center at the College of Staten Island. — jta
