Police on Friday released the name of a woman who was killed in an early-morning crash in Cumberland.
Police said 22-year-old Brianna Hallenbeck, of Cumberland, died when the car she was driving struck a tree on West Wrentham Road at about 1 a.m.
According to police, the crash was unnoticed for hours because the car went down an embankment.
Neighbors told NBC 10 they heard a loud noise at about 1 a.m., but the crash wasn't reported until seven hours later.
Police said they believe speed was a factor in the crash.
