RONKONKOMA - Two people are dead after a head-on collision in Rokonkoma.
Police say the accident was caused by 33-year-old Brian Mullady who died on the scene.
The other victim, Andrea Giattino, 19, was the passenger of the other car, driven by her boyfriend Justin Quaranta.
Quaranta?s father tells News 12 that Giattino alerted his son something was wrong, when Mullady?s vehicle crossed over the center lane on Smithtown Road.
Police say Giattino was wearing her seat belt and the airbags did deploy, but exactly what caused the Dodge pickup truck to swerve into oncoming traffic is unclear.
Quaranta was treated and released only suffering minor injuries. Police have impounded both vehicles for a safety check.
