SPOKANE — Spokane Valley firefighters say they sent three adults and an infant to hospitals for treatment of carbon monoxide poisoning.
The fire department says crews had responded to a medical call at a home and were treating a 21-year-old woman Thursday morning when their carbon monoxide monitors sounded an alarm.
A local utility was investigating the source of the gas.
The condition of the four people was not known.
