CONWAY, Mass (Reuters) - A New York man suspected of committing a triple murder in New York and then abducting his girlfriend and their infant son and fleeing by car to New England waived extradition on Thursday to face those criminal charges.
Matthew Slocum, 23, was arraigned in Cheshire County Court in Keene, New Hampshire, on Thursday as a fugitive from justice, said David Lauren, assistant county attorney.
Slocum surrendered to police late on Wednesday in Gilsum, New Hampshire, where he had been hiding in a house with his girlfriend Loretta Colegrove, 25, and their 4-month-old son Raymond, authorities said. The baby and mother appeared unharmed.
"He waived extradition so he will be going back to New York, and it's anticipated it will be done sooner rather than later," Lauren said.
Authorities said Slocum was a suspect in Wednesday's early morning house fire that killed three people in White Creek, New York, about 35 miles northeast of Albany.
The so-called Amber Alert system was activated on Wednesday in New York, Massachusetts, and New Hampshire after police say an armed Slocum fled New York with his infant son, who, along with Colegrove, was thought to be in extreme danger.
A black 2003 Ford Mustang two-door driven by Slocum, previously of Cambridge, New York, first was spotted in Adams, Massachusetts early on Wednesday. It later was found abandoned in Gilsum, about 80 miles to the northeast, that evening.
Police eventually surrounded a residence in the small town 8 miles north of Keene, where Slocum surrendered.
