A 19-year-old from Mahopac died after the car he was driving left the roadway and slammed into Mahopac High School Friday. 

David Diachenko was behind the wheel of the 1990 BMW that smashed into the school's science wing at about 11:30 p.m. Friday. Police say no one else was involved in the crash, which left the building damaged. 

"The autopsy determined that his death was caused by blunt force trauma to the upper torso that caused severe internal bleeding," said Carmel Lt. Michael Cazzarri. "Police are awaiting the toxicology report and the completion of the accident re-construction analysis."

Carmel police officers, members of the Mahopac Falls Volunteer Fire Department and Ambulance Corps, and a Transcare paramedic responded to the accident scene and gave medical attention to the driver. Putnam County Sheriff's deputies assisted, as did members of the department's accident reconstruction team.

School will be in session Monday, but three classrooms will be offline, Superintendent Thomas Manko said in an email to community members Saturday night.

The school will be open from 3 to 5 p.m. Sunday, Feb. 23, for students and parents who have been affected by the tragedy. Counselors and clinicians will be there.

Fire officials told News12 that the victim "barreled down" Gleneida Boulevard gaining "so much momentum that he crashed" into the school. The school sits on Baldwin Place Road, which intersects with Gleneida, a steep hill.

"Please note that all precautions regarding the magnitude of this event have been taken regarding obligatory notification of the Department of Environmental Conservation," Manko said in the email. "Air monitoring has already begun and will continue thoughout the weekend. Security has been posted."

Police are continuing their investigation.

Thoughts and prayers to the boy's family and for the boy's troubled soul. It seems reasonably clear that this was not an accident. We should be asking why the police have not stated that the scope of their investigation will include that possibility. We should also ask why the crackerjack 'journalists" at Patch did not raise this possibility either in their story above.

PatchRat, I don't believe it is the function of journalists to speculate or conjecture (as you have done). I for one appreciate that Ms. Tarr is keeping us apprised of the FACTS in this unfortunate tragedy. Prayers to the family and friends of this young man.

"We" should be asking? PatchRat are you a family member or friend? Because I know that I am not therefore making it none of my business and not my place to ask any questions about this incredibly sad event.
