ROCKLAND — Seven people were taken to Pen Bay Medical Center over the weekend from two separate car crashes.

The first occurred July 23 at about 9 p.m.

According to Rockland police, a vehicle driven by 23-year-old Nellie Harvey went through a flashing red light while traveling south on Old County Road at the intersection of Route 17. Harvey’s vehicle was then struck heading east on Route 17 and by Rachel Jameson, 38, of Rockland. Jameson had a flashing yellow light.

The impact flipped Harvey’s vehicle.

Four occupants of Harvey’s vehicle were taken to the hospital. Harvey declined treatment. All three occupants of Jameson’s vehicle, including herself, were taken to the hospital. The extent of injuries were not known.

Harvey was issued a summons for not stopping at a flashing red light, police said.

Many traffic lights in Rockland were flashing July 23 and into July 24. There was an electrical storm earlier July 23, but city officials were uncertain of what led to the traffic light issue.

On July 25 before 4 p.m., a Chevy Camaro driven by Theodore Larkin, 33, of Warren, crashed into a utility pole between Broadway and Holmes Street. The impact broke the pole, which had to be replaced.

Larkin suffered significant injuries and was taken to the hospital. A witness reported hearing the vehicle rev up before the crash.

The case remains under investigation.
