Investigator Thomas O'Neill suffered a fatal heart attack shortly after a struggle with a suspect.

Investigator O'Neill was on duty and had stopped his department Vehicle at a Mobil Gas Station on Wicks Road in Islip.

A struggle ensued and Investigator O'Neill was able to get the suspect handcuffed. He then called for an additional unit to transport the suspect.

Two troopers transported the suspect back to the Brentwood Station, and a third trooper accompanied Investigator O'Neill in his vehicle. While en route, Investigator O'Neill complained of chest pains and asked the other trooper to drive. When they arrived at the Brentwood station, Investigator O'Neill collapsed. He was helped up by other troopers, but collapsed again as an ambulance arrived. Efforts to revive him with CPR were unsuccessful. Investigator O'Neill died while en route to the Hospital.
