A woman named Suzanne Morphew went missing on May 10 in Chaffee County, Colorado and the search for her continues months later.

Most recently, the woman's brother, Andrew Moorman, conducted a multi-day private search in the area with hundreds of volunteers. In a recent Facebook post, the Chaffee County Sheriff's Office indicated that law enforcement has collected several pieces of what they're calling "possible evidence" in the disappearance.

According to the Tuesday press release, a law enforcement team previously responded to a scene where the "possible evidence" was found and will be conducting further analysis. Details about what was found have not been released.

In recent days, law enforcement has also responded to human remains-trained dogs indicating something of interest at three separate locations – none of which occurred on property owned by the Morphew family.

In the first instance, law enforcement responded to a site along the Arkansas River where a dog was showing interest. Upon investigation, it was determined that this was not connected to the case. The same dog later indicated something of interest on a property near the Morphew home, though again, nothing was found.

In the third instance, a pair of different dogs indicated that they had found something in unincorporated Chaffee County. An excavation revealed nothing of value to the missing persons case once again.

Throughout the course of the investigation, 1,123 calls have landed on a designated call line. Authorities have conducted 180 interviews in multiple states and more than 130 searches have been conducted. The Chaffee County Sheriff's Office estimates that more than 4,000 hours have been spent by investigators on the case.

Anyone with information that could help law enforcement locate Suzanne Morphew is encouraged to call 719-312-7530.
