BATH — A Brunswick man accused of causing an accident that sent four people to the hospital has been charged a month later with aggravated drunken driving.

Bath Police Lt. Stan Cielinski says an investigation revealed 22-year-old Joseph Boyington was under the influence of alcohol and speeding at the time of the March 19 crash.

Cielinski’s vehicle crashed into a sport utility vehicle in Bath, causing severe injuries to his passenger, who police say remains hospitalized. Boyington also suffered serious injuries but was later released from the hospital. The two occupants of the SUV were treated and released.

The Times Record says Boyington, who surrendered to police on Friday, was released on $500 cash bail. There’s no telephone listing in Brunswick for Boyington and he couldn’t be reached Monday.
