A Long Island science teacher was killed in a skiing accident when he hit a tree at Vermont’s Killington Resort, police said.

Jason Vitale, 48, was speeding down intermediate slopes Saturday around 3 p.m. when he lost control and rammed into a tree, according to Vermont State Police.

Vitale, who wasn’t wearing a helmet, went into cardiac arrest and was rushed to Rutland Regional Medical Center, where he died.

The Baldwin resident, who was married with a young daughter, had been a “well respected” science teacher at Mepham High School, Bellmore-Merrick Superintendent John DeTommaso said in a statement to Newsday.

“He cared about kids and families and will be missed by the entire Bellmore-Merrick community,” DeTommaso said.

Mepham Principal Eric Gomez asked the community to “join me in sending prayers and condolences to the Vitale family during this difficult time,” in a statement Sunday.

In addition to teaching, Vitale had been an active member of the community, and the quality-of-life chair for the Baldwin Civic Association, according to a Long Island Herald article that quoted him earlier this month.

“RIP my childhood friend Jason Vitale, I’m heartbroken,” one person wrote on Facebook. “Heaven gained an angel.”
