Grief counselors were on hand for students at Lindenhurst High School Tuesday as investigators try to determine what caused a crash that killed their classmate.  

As News 12 Long Island has reported, four people were in a Mustang around 5 a.m. Monday when it went up on the sidewalk, hit a fire hydrant and crashed into a tree along North Wellwood Avenue. 

Two Lindenhurst High School students were among the four people in the car. Joseph Galdorisi, 16, was killed. Daniel Ozarowski, also 16, is in critical condition.

Joseph Galdorisi's mother told News 12 that her son "was a beautiful boy with a soft side and caring heart and a great sense of humor."

People in the area have since left flowers and candles at the site of the crash. 

Police say 17-year-old David O'Brien was behind the wheel. Investigators say alcohol did not play a role in the crash, but they have not yet ruled out distracted driving, drugs or speeding. 

Neighbors tell News 12 that the stretch of North Wellwood Avenue is known for being dangerous and notorious for speeding.

Galdorisi's wake will be held at the Lindenhurst Funeral Home on Thursday from 7-9 p.m. and Friday from 2-4 p.m. and 7-9 p.m. His funeral Mass will be held Saturday morning at Our Lady of Perpetual Help in Lindenhurst.
