DOVER – Firefighters ask residents for help in their investigation of two fires along New York Street Saturday night, which could be connected and are considered suspicious, according to Assistant Fire Chief James Ormond said.

Firefighters first extinguished a burning Jeep which melted the façade of 4 New York St. before responding to a three-alarm fire in a vacant home at 34 New York St. around 9:50 p.m.

“It was a busy night,” Ormond said. Firefighters from neighboring communities in both New Hampshire and Maine responded to assist at the scene.

Ormond said the fire was under control just after 11 p.m. and most fire crews cleared the scene around 2:30 Sunday morning. He added one team of Dover firefighters kept watch overnight as a precaution, to ensure the fire didn’t restart.

Ormond said firefighters consider both fires to be “suspicious at this time” as the investigation continues. He added investigators have not found evidence to prove the fires are connected or not.

“All we know is that it (the Jeep) was on fire,” Ormond said.

Anyone who saw anything suspicious in the area or who has more information about either fire is asked to call police at 742-4646 or leave an anonymous tip with the Dover Crimeline at (603) 749-6000.
