Fort Collins police have called the circumstances surrounding the disappearance of a 41-year-old woman "suspicious."

Kimberlee Graves was last seen at her home the night of Dec. 4, 2017.

A few days later, when a friend couldn't reach Kimberlee, she called police to request a welfare check.

On Dec. 8, police called on Kimberlee's home. No one answered the door and her car was gone, police said.

Two days later, the same concerned friend went into Kimberlee's home on Akin Street and discovered it had been ransacked. She called police again.

Police arrived and began investigating, a news release from Fort Collins police said.

Then, almost a week later, detectives found Kimberlee's SUV abandoned. The red Toyota Rav4 had been left in a parking garage at College Avenue and Mulberry Street. It was discovered on Dec. 13.

While detectives have not found evidence of injury, the suspicious circumstances have caused concern for her safety, a news release said.

“I keep sharing her stuff on Facebook and put it out there,” Daniel Cordova told 9NEWS on Monday.

Cordova has been Graves’ neighbors for close to eight years and has been watching police, who left behind evidence markers on the front door, over the last few days.

“They were here around-the-clock for about four days straight,” Cordova said.

His concern grew for his friend who, Cordova says, is a mother of two. Despite the fact that neighbors say the 41-year-old is a mother, police say they are only looking for Graves.

“There’s no evidence that would indicate injury to Kimberlee, but because of the kind of suspicious circumstances, we are asking the community’s help to locate her,” said Kate Kimble, the public relations manager for Fort Collins Police.

Graves has been missing for two weeks. Police say they’ve been investigating ever since she was reported missing.

They're now at the point they need more help.

“We need to cast the nest a little wider to find out if anyone in the community might know where she might be,” Kimble said.

Graves' LinkedIn indicates she is a massage therapist.
