State police have charged a 50-year-old woman in connection with a car versus pedestrian accident in the parking lot of RHAM Middle/High School in Hebron that led to the death of a longtime teacher from Groton.

Police said investigation into the March 14 incident that caused the death of 65-year-old Dawn Mallory-Bushor led to the arrest of Elizabeth Everett of Hebron. Everett turned herself in to state police at Troop K in Colchester to face charges of misconduct with a motor vehicle and unsafe backing.

At the time of the accident, state police said Mallory-Bushor was struck by a car that had pulled into the school bus loading and unloading zone, stopped, then tried to back out about 7 a.m.

School officials at the time said Mallory-Bushor was walking behind the car when she was hit by the tailgate of the vehicle, fell and hit her head on the pavement.

She was taken to Hartford Hospital in critical condition and died on March 28.

Mallory-Bushor was a mother of two sons and was a school teacher for more than three decades. At the time of her death, she was teaching at RHAM middle school and Three Rivers Community College in Norwich while running a tax preparation business from her home.

In a statement announcing Everett’s arrest, state police did not provide any details of the investigation that led to an arrest warrant being signed on July 25.

Everett is free after posting a $100,000 court set bond and is scheduled to appear on Aug. 12 in Rockville Superior Court.

Misconduct with a motor vehicle is a Class D felony with a maximum penalty of five years in prison. According to state law, “a person is guilty of misconduct with a motor vehicle when, with criminal negligence in the operation of a motor vehicle, he causes the death of another person.”
