(AP) CONIFER, Colo. - Authorities said Friday that they were investigating problems with an emergency notification system because some residents who had signed up to get wildfire warnings never got one.
About 12 percent of people failed to get a warning about a wildfire in the mountains southwest of Denver on Monday. Jefferson County sheriff's spokesman Mark Techmeyer said that some of those people likely hung up after hearing the pause that precedes the automated message or that their phone may have been busy.
He said there was no attempt to reach an unknown number of other people registered to get them.
The company that handles the system, FirstCall Network Inc., has said it worked exactly as it should, but Techmeyer said the county needs to find out more about what happened.
Company president Matthew Teague was traveling Friday and didn't immediately respond to an email seeking comment.
The calls went out in two waves, and the first wave included a number of people outside the evacuation area and some outside Colorado. He didn't know the locations of the out-of-area phones that got calls, or the times of the two waves.
Sheriff's officials said they were trying to get more data from FirstCall but said that may take a while. They voiced frustration with the company.
"If we have to get a new provider, we will," sheriff's spokeswoman Jacki Kelley said.
Firefighters were working to contain more of the 6-square-mile wildfire, which was apparently sparked by a state controlled burn that sprang to life because of strong winds. Winds were forecast to return Saturday but not expected to be as strong as originally predicted.
Residents of about 180 homes remain evacuated. At the height of the fire threat, residents of about 900 homes were to flee.
Coe Meyer on Thursday viewed his burned home for the first time since leaving. He criticized the state for conducting a controlled burn after such a dry March.
"The trappings of 62 years are gone," he said.
Mary Thuente said her neighbors got an automated call warning them to flee their homes, but she never got one before she left.
Jack Ogg doesn't think he got a telephone warning either, though it's possible it may have come while he was outside rounding up his dogs and his neighbors' pets. After that, he rushed away with 15 people and animals squeezed into his Jeep after firefighters asked him to take neighbors with him.
A couple found dead in the burn area Sam Lamar Lucas, 77, and Linda M. Lucas, 76 received an evacuation call, but it was not clear when, Kelley said.
Ann Appel, who remains missing in the fire zone, also was called, Kelley said. Techmeyer said a search team planned to scour another 80 acres inside the zone on Friday.
