Here's what I've found about the phone, after a quick google search, BBM
"Noel B. Richards, 19, said Ms. Marcotte’s aunt approached him at his home on Ball Hill Road around 4:30 p.m. Sunday, desperate to find Vanessa and asking if he had seen her. Mr. Richards said the woman was parked on the side of the road looking for Ms. Marcotte. He said he had never met the woman before and did not know the family. The woman told him that Ms. Marcotte left her mother’s house around 1 p.m. for a run, he said, and had a bus ticket for 4:30 from Worcester to New York, but hadn’t returned.
'She was in desperation and had already called police,' Mr. Richards said. '
She (her aunt) told me the last ping to her niece’s phone was at 2:25 in the Mountain Barn (Restaurant) area. Then she saw a state police car driving down the road and chased it'"
