Officials say it was a carbon monoxide emergency which led to a heavy police and fire presence at a home on Deerpath Drive in New Hartford on Thursday morning, just before 9 a.m.. Witnesses say New Hartford Police and Fire, State Police, the Oneida County Sheriff's Office, and National Grid were all at the scene.

Carbon monoxide poisoning can mimic the flu with headaches, dizziness, nausea, or weakness—and without a detector, you’d never know it’s happening.
