A woman charged with drunken driving after an early morning, single-car accident in Southampton Village on April 19 in which a Water Mill man died has been indicted by a Suffolk County grand jury on multiple felony charges, including vehicular manslaughter. Allison Rydberg of Hampton Bays was arraigned Monday in Central Islip before acting Supreme Court Justice Fernando Camacho. The vehicular manslaughter charge was based on a police statement that her blood-alcohol content at the time of the accident was over .18 of 1 percent. Ms. Rydberg, 25, was charged with three additional manslaughter charges, including recklessly causing the death of her passenger, Jason H. Pollak, 24, of Water Mill. Also included in the indictment were three misdemeanor charges and a speeding violation. The two most serious charges are C felonies, which could each result in a sentence of up to 15 years in state prison. She is free on $75,000 bail. Her next court appearance is on July 30.
