A police officer with no prior history of domestic violence fatally shot his wife and son and set the family's suburban Albany house on fire before killing himself, authorities said.

Police revealed details Thursday about 44-year-old Israel Roman's actions at his home on Tuesday in Colonie, where he served the past 12 years on the police force.

State police said Roman used his service handgun to kill his wife, Deborah, 44, and their 10-year-old son, Nathan. Police said they believe Roman placed the bodies on the bed in the master bedroom, started a fire and shot himself.

Firefighters responding to the home discovered the bodies.

Colonie police officials describe Israel Roman as a dedicated, decorated officer who had no history of behavioral problems prior to Tuesday.
