CENTENNIAL — A passport, a Kindle, a sim card and $180 are all 22-year- old Brendan Davis took with him when he vanished from his Boston apartment last week, leaving his family in Centennial desperately trying to find him.
Davis, who graduated from Heritage High School in Littleton in 2007, was two weeks away from his bachelor’s degree in computer science at University of Massachusetts Boston.
“It’s very uncharacteristic of him to just leave without making plans. He’s a very organized individual,” said his mother, Caralyn Davis. “We just need to know he’s safe.”
Before disappearing Wednesday, Davis sent two cryptic letters: One to his ex-girlfriend asking her to take care of his cats and one to a close friend giving him a set of keys and permission to use Davis’ apartment.
Davis has struggled with bouts of depression since breaking up with his girlfriend of three-and-a-half years in November, his mother said.
