---- — WHEAT RIDGE, Colo. — Colorado police say their investigation into the disappearance of St. Peter native Leann "Annie" Meyer is shifting into a criminal investigation.
During a Tuesday press conference, Wheat Ridge Police Chief Dan Brennan offered condolences to the family and said the investigation has been a "long and arduous process." He said the case is their "top priority."
Meyer's remains were discovered July 4 by people who were walking near their home and the remains were identified over the weekend.
Meyer, 52, was reported missing from her Wheat Ridge home in February.
A team, including the Colorado Bureau of Investigation, worked the scene for several days. The property owners are not suspects. An investigator said there were signs of "significant animal activity" near where the remains were found.
Meyer's roommate, Melissa Miller, remains a person of interest in the case but she has hired a lawyer and is not cooperating with police.
Meyer's family last heard from her on Feb. 10 when she spoke to her mother on the phone. Her co-workers reported her missing on Feb. 27.
Meyer's mother and eight siblings, some from St. Peter, have made multiple trips to Colorado assisting in the search for her.
Meyer's 1995 silver Toyota pickup and her other vehicle, a 2009 RAV4, were recovered in different locations, away from her home, days after her disappearance.
In May, some of Meyer's friends confronted Miller. According to the CBS affiliate in Wheat Ridge, a witness to that confrontation said Miller admitted abandoning Meyer's SUV, but said she did so because the house was locked. The witness said Miller also said that there was blood in the vehicle that came from a bloody nose Meyer had.
Meyer's brother, Mark Meyer, told a Denver TV station that "we are now at the point that we hope to find out exactly what happened."
