Update at 9 p.m.
East Haven Fire officials now have their second ongoing suspicious fire investigation after Saturday's early morning blaze at 20 Harmac Drive has been ruled an arson.
East Haven Fire Marshal Anthony Moscato and the State Fire Marshal's Office spent much of the day at the long-vacant home, piecing together how the fire started and spread.
EHPD Assistant Fire Chief Chuck Licata told East Haven Patch that investigators found "more than one point of origin" for the fire.
In addition, a fire dog trained to sniff out the use of accelerants at the site of a suspicious incident had positive hits. (see video posted in the gallery)
"We're ruling it an arson," Licata said, adding that East Haven Police officers were already out in the neighborhood Saturday afternoon "canvassing neighbors" for any information that might lead to a suspect or suspects that started the blaze.
Neighbors told East Haven Patch that the single-story house has been unoccupied for about six years now after a bank foreclosed on the home. The bank, they said, still owns the property.
East Haven Fire officials are asking anyone with information about Saturday's fire to call the state's Arson Tip Line at 1-800-84ARSON (1-800-842-7766).
Or, those with any information can contact the East Haven Fire Department at (203)-468-3840 or the East Haven Police Department at 203-468-3820 or email firstname.lastname@example.org.
East Haven Patch will continue to provide additional updates as this story moves forward.
