AMHERST — Two cars parked at an Amherst apartment complex were destroyed after catching fire in the early morning hours on Memorial Day, according to Amherst Fire Chief Lindsay Stromgren.

Firefighters responded at 1:19 a.m. Monday to a box alarm, summoning both on-duty and off-duty units, to Olympia Oaks, the apartment complex off Olympia Drive.

Stromgren said the original 911 call had suggested the fire was getting close to a dwelling unit, though turned out to not be the case. Firefighters from one engine quickly extinguished the cars, but not before both were totaled, Stromgren said.

No cause has yet been identified. The fire started at an unusual time of day when neither car had likely been operating, which raises questions, he said. A state police investigator assigned to the state Fire Marshal’s Office is investigating, though no results have come back yet.

The incident came before Amherst dispatched an ambulance, at 4:05 a.m., to Granby to assist with a multi-alarm fire at a home.

Due to the incidents at Olympia Oaks, with a duplex heavily damaged after an e-bike caught on fire last September and the proximity to the Olympia Place apartment building that was destroyed by fire last November, Stromgren said Community Responders for Equity, Saftey and Service will be doing outreach to calm concerned residents.
