Larrecsa Cox is a paramedic, but instead of an ambulance with flashing lights and sirens, she drives around in an old, white sedan.
Her first call on a recent day in Huntington, W.Va, was to a quiet, middle-class neighborhood.
"He overdosed yesterday," Cox says. "And I think we've been here before. I'm almost 100 percent sure we've been to this house before."
Cox is the only full-time member of Huntington's new quick-response team — a collaborative project involving law enforcement, the county's medical first responders and several drug treatment providers.
