Law enforcement officials throughout Colorado were on full alert after Shiann Moore and her three children were reported missing by family members.
By 10:30 a.m. Wednesday, the four were found safe on the Front Range in Evans, almost 300 miles away from their Clifton home.
"Thank you everyone for [your] help in finding Shiann Moore and the kids they were found safe and coming home," Terri Phinnell posted to Facebook on Wednesday. Phinnell indicated that she was Moore's mother.
"Thank you to all in assisting in the safe return of my family," she posted later in the day.
Mesa County Sheriff's Office spokeswoman Megan Terlecky said family members reported them as missing on Monday evening, as they hadn't been seen or heard from for several days.
The family members described their absence as "very uncharacteristic," according to Terlecky.
By early Tuesday afternoon, the Sheriff's Office put out information through its social media pages and by notifying news media.
By 6 p.m., an Endangered Missing Person Alert was put out by the Colorado Bureau of Investigation to spread the alert statewide.
On Wednesday morning, the four were spotted in Evans, a town just south of Greeley, by a citizen who recognized them from the alert. The Evans Police Department was able to confirm their safety.
"Our role was to find them and make sure they were safe and that's what we did," Terlecky said. "We are very thankful to have great community members and tools at our disposal."
