Leann "Annie" Meyer had been living in Wheat Ridge, Colo. Her remains were found Thursday evening near a cabin in Park County, family and friends told the newspaper.
Wheat Ridge police plan a Tuesday news conference to offer more details. The Park County sheriff has called the investigation a homicide probe, the Post reported.
"It's just unbelievable," Mark Meyer, Annie Meyer’s brother, told 7 News, the ABC affiliate in Denver. "There is some relief now."
Meyer's family has suspected foul play. Two of her vehicles were found in March.
Pat Meyer last heard from her daughter in February, and she has been to Colorado five times to search for her daughter, KARE 11 reports.
"Hopefully the detectives, I don't know how long it might take to give us some answers and maybe there isn't any," Pat Meyer said. "We hope there are. We hope we know who did this to her. We hope to find out."
Meyer grew up in the Mankato area, KARE 11 has reported, and she has family members in Minnesota who have been active in a search for her.
