Weekend blazes plague North Shore

North Shore firefighters kept busy on Saturday night into early Sunday morning battling three separate house fires in Revere, Lynn and Peabody.The most serious blaze occurred in Revere, where a home at 64 Warren St. received extensive damage after the fire reached two alarms at 1:45 a.m. Sunday.Firefighters first responded at 1:23 a.m. when flames were shooting through the roof, according to Deputy Chief Ronald Cook.Crews fought the blaze at the vacant two and-a-half-story wood frame until nearly 6 a.m., Cook said.He added the fire had “a good head start” before firefighters got there. Cook said often times when fires have a burned for a while before anyone is called, it indicates it could be suspicious. However, he said a suspicious cause hasn’t been determined and it’s still under investigation.In Lynn, a chimney fire spread to the walls of 41 Pennybrook Road shortly after 9:30 p.m. Saturday, causing serious damage to that home as well.The fire originated in a fireplace, according to Fire Chief Jack Barry. The flames damaged the living room and a second-floor bedroom, Barry said.Peabody firefighters quickly knocked down a fire at 15 Ruth Ave. shortly after 9 p.m. Saturday. Similar to the Lynn fire, the flames started in a chimney before spreading to the walls and the attic of the one-story wood home.
