David Dahl vanished in the bone-cold November darkness with no car, no phone and no hint of when he might return.
His disappearance on foot has left his family and police in Anoka County grasping for answers in a case where they don't suspect foul play. Searches by law enforcement and others have so far come up empty for the 56-year-old longtime machinist, who his family says had struggled with mental health issues.
That's where Deanna Villella and her team of volunteers come in.
Villella and her United Legacy organization deploy awareness campaigns, ATVs, helicopters, horses and specialized equipment to continue ground searches for people like Dahl. Law enforcement can dedicate only so much time and manpower to such searches, but United Legacy doesn't stop looking until families ask.
Villella started the group after her own brother's disappearance in 2014. Now the young nonprofit is making a name for itself among law enforcement departments and families, having successfully aided in several high-profile searches across Minnesota.
"When we take on any case, we stay with the family until they have answers," said Villella, 40, a Minnesota native who quit her job as a personal chef to run United Legacy full time. "It doesn't matter if it's a month or 10 years."
And there's no shortage of work to do, with several new cases coming in weekly, she said.
Minnesota law enforcement officials file about 11,000 missing person reports each year, according to the Bureau of Criminal Apprehension. Nearly 80 percent involve children.
