Annie Meyer's roommate, Melissa Miller, due in court on murder, domestic violence charges Tuesday

PARK COUNTY, Colo. - Annie Meyer's roommate, Melissa Miller, faces a judge in Park County Tuesday in connection with the Wheat Ridge woman's killing.

Miller was arrested Monday on murder and domestic violence charges, police said.

Annie Meyer disappeared in February and, even though her friends and family launched extensive searches for her, her whereabouts weren't known until a group found human remains near a cabin in Park County on July 4. Last week, the remains were confirmed to belong to Meyer.

Miller's friends and family told 7NEWS that Miller had planned to go to the Wheat Ridge Police Department on Monday to talk to investigators.

"She said, 'I'm on the way to the police department. They called me, and said they needed to speak to me,'" said Miller's longtime friend Julia Romero. "I know in my heart of hearts that she didn't do it. She's not guilty. She loved Annie too much."

It's unclear what she told police. However, the 54-year-old Miller was arrested Monday afternoon at the police station, said John Romero, Wheat Ridge police spokesman.

Wheat Ridge police previously said Miller had not talked to them about Annie's disappearance and had not cooperated in the investigation.

However, Miller told a different story to Annie's friends and family in a confrontation covertly recorded before the body was found.

In the video, Miller says she has been cooperating with police all along, even authorizing the initial search of the house she shared with Annie for nearly three years.

Miller was transferred to the Park County Jail in Fairplay, where she is being held without bond.

Miler's mother, Mary Trounce, said her daughter had nothing to do with Annie's disappearance, but had hiked with her frequently in Park County, where the body was found.

Trounce said Miller attempted suicide shortly after Annie's disappearance because of the cloud of suspicion.
