Hardly a day passes without Andrea Aistrop making a plea on social media about her missing father, who disappeared nearly four months ago.
Family members and police remain on the lookout for tips about the whereabouts of David Dahl, who went missing Nov. 14 near the 7600 block of 181st Avenue NW. in Ramsey. The family is offering a $1,000 reward for information that leads to his whereabouts.
Police say no foul play is suspected in connection with the disappearance of Dahl, 56, who was last seen on foot without either a cellphone or car.
Searches with dogs, all-terrain vehicles, drones, a helicopter and a special machine tracker used to scour marshy areas have so far come up empty, according to authorities.
"It's an open and active investigation," said Ramsey Police Chief Jeff Katers. "We still continue to follow up on all leads or possible sightings."
Aistrop said her father had been released from the hospital a few days before his disappearance and has struggled with mental health issues. Family members say Dahl had been homeless before and may have sought shelter in a barn.
Dahl, who worked for years as a machinist, often spent time in the Nowthen area. "He was the type of person who would give you his last $5," Aistrop said.
United Legacy, a search and rescue organization, has conducted searches and is planning another private volunteer search once the snow clears, Aistrop said.
