CONIFER, Colo. (AP) -- Authorities in Colorado say they're investigating how well their emergency telephone notification system works because some residents who signed up never got a warning about a wildfire.
Jefferson County sheriff's spokesman Mark Techmeyer said Friday that an unknown number of people who signed up weren't called.
The company that provides the system, FirstCall Network Inc., says everyone who signed up for the system did get a call.
Company President Matthew Teague says the county can determine which phones, if any, weren't called by comparing phone numbers in the system with mapping and telephone data.
Teague says his company is working with county officials to provide the data they need.
Two people died in the fire and a third is missing. The fire destroyed or damaged at least 25 houses.
