State Police say a woman at first believed to have been a passenger in a fatal accident on Interstate 84 in Waterbury eight-and-a-half months ago now faces charges in the crash — and also is charged with being the driver and with making a false statement to police.

Police say 21-year-old Kaleigh Morgan of Waterbury was injured in the accident last Feb. 20,  when the Volvo she was in,  travelling eastbound in the westbound lanes, collided head-on with a Toyota Rav 4 owned by the Abbey of Regina Laudis in Bethelehem.

The woman believed at the time to be driving the Volvo,  20-year-old Amanda Grenier of Waterbury, was killed in the accident.  Both Morgan and the driver of the Toyota,  Monica Evans,  were injured.

After their investigation,   State Police determined Morgan had been driving and Thursday afternoon they arrested her,  charging her with driving the wrong way,  manslaughter,  operating under the influence, and with making a false statement and interfering with police in their investigation of the accident.
