"It's just a devastating thing," said Kristin Matteau, the mother of the victim's boyfriend. "You have no idea what just rushes through your head."
Croteau lived with Matteau and her family. She said the 21-year-old was headed back to their home in Manchester after visiting her mother in Milford, N.H.
"She had just got out of work, I think at 9 or 10 o'clock at night. She went to her mothers to visit a little bit," Matteau said. "And she left there to come home, and Tyler left her two messages on her phone and she never replied. Quarter of 4 this morning we found out why."
Berry was seriously injured in the crash and taken to Catholic Medical Center in Manchester, and was eventually arrested at the hospital and charged with felony aggravated driving under the influence of alcohol.
Kim Bernard, operations captain for the Londonderry Police Department, confirmed that Berry worked for the department.
