Amber Alert Deactivated For Missing N.Y. Infant

Update: An Amber alert issued for Matthew Slocum, 23, his girlfriend, 25-year-old Loretta Colegrove and their infant has been deactivated. Police say Slocum, who is wanted for questioning in connection to a triple homicide in New York, is in custody. His girlfriend and their child are safe.

Matthew Slocum is the son of Lisa Harrington, who died in the fire early Wednesday along with her husband, Dan, and his son Josh in White Creek, 35 miles northeast of Albany, state police said.

The Amber alerts were issued after Slocum left the burning home in a black 2003 Ford Mustang. He was reported near Adams, Mass., at about 5 a.m., and authorities said the empty vehicle was found late Wednesday afternoon in Gilsum, N.H., 75 miles northeast of there.

Guns known to be in the home couldn't be accounted for, and police told the Glens Falls Post-Star they were asking neighbors whether they heard shots before the fire.

Dan Harrington was a deputy highway superintendent. "They were good people. Dan was a real good employee," White Creek town Supervisor Bob Shay told the Post-Star. "We all feel horrible. It's just so sad."

He said Harrington and his wife served on the town recreation committee.

Slocum went to prison in 2006 for breaking into a house and stealing cash, a New York prison spokesman said. He was released but returned to custody twice for violations before his parole expired in December 2009.

On Wednesday afternoon, emergency crews remained on the scene of the charred remains of the house, set back from a remote country road on heavily wooded property.

Police haven't released any information about the cause of the fire.
