An alleged drunken driver crashed head-on into another vehicle in Brentwood early Saturday morning, seriously injuring the passenger of the car, Suffolk County police said.

Ronald Cherry, 44, of Bay Shore, was arrested and charged with driving while intoxicated. He will be arraigned Sunday at First District Court in Central Islip.

Police said Cherry was driving a 2006 Chevrolet Malibu eastbound on Spur Drive North just before 2 a.m. when he was involved in a head-on collision with a 2008 Toyota Avalon driving westbound.

The driver of the car, 43-year-old Bernadette Joachim-Baker of Miami, was taken to Southside Hospital in Bay Shore for minor injuries. Her passenger, 21-year-old Melissa Joseph of Brentwood, was transported to Southside with serious injuries, police said. Police earlier in the day incorrectly reported that another passenger had suffered serious injuries.

Cherry was treated at the same hospital for minor injuries.

Police said the investigation is continuing. Anyone with information is asked to call Third Squad detectives at 631-854-8352 or Crime Stoppers at 1-800-220-TIPS.
