Kara Nichols search: Mom says teen model was involved in drugs, prostitution

Big photos below.

Last November, we told you about the search for Kara Nichols, an aspiring teen model from Colorado Springs who'd vanished en route to Denver. At the time, a photo on the website of a Las Vegas escort service was alternately thought to be a false lead or a big break. Now, we know why it was taken seriously: Nichols's mother reveals that her daughter had been involved with drugs and prostitution.

As we've previously reported, here's how Nichols describes herself in a self-penned bio for the Model Mayhem website:

My name is Kara and I'm 19 years old. I've been modeling since February 2012, and although I'm new to it modeling is something I am very passionate about and I take my work seriously. Currently I'm working on building my portfolio so I'm always looking for modeling opportunities in my area. I've done mostly lingerie shoots so far but I'm extremely open minded and I'm willing to work with you on ideas for shoots so contact me if you're interested in working with me!

One of many photos of Kara Nichols shared on the Help Find Kara Nichols Facebook page.

The bio ends with this postscript, which speaks volumes about the world of modeling:

NOTE TO PHOTOGRAPHERS -- due to my financial situation I am mainly focused on paid work. I am still open for TF shoots but paid work takes priority for now. Please contact me for serious requests only.

As for the details of Nichols' disappearance, they're provided on the Help Find Kara Nichols Facebook page:

Kara Nichols left her home at 6700 block of Mission Road in Colorado Springs bound for Denver on October 9th only to not be seen again. The last call on her cell phone was at 11:45 p.m. October 9, 2012.

More information appears on this missing persons flier:

Nichols is said to have traveled to Denver in the company of two women whose names have not yet surfaced. Law enforcers reportedly interviewed one and were on the lookout for the other.

Then, in late November: a photo of Nichols turned up on what's described as a "Las Vegas escort-based website." This news prompted a flurry of reports that Nichols may be in Nevada working as a prostitute, even though it's not exactly a requirement that such sites post the actual photos of those in their employ.

Afterward, Nichols's family shared the following message:

We ask reputable media networks and the public to continue to report the fact Kara is missing and has been since October 9th. There has been no communication with anyone, no login of any social media sites and with no attempt to access her cell -- for us, whatever happened to Kara happened on October 9th and we have no leads to prove Kara is in Vegas or in any position she can reach out for help. We thank investigators for following up on these cruel hoax attempts and addressing the rumors so they can get back to the real investigation of finding our daughter.

Please continue using the flyers and photos on this site -- these are the only one approved by investigators and the family. Any other materials you may think are valid are not. We know someone out there knows where our daughter is and what has happened to her, we ask you to call Detective Porter immediately or e-mail your tip into investigators.

Detective Cliff Porter at (719) 390-5555 or findkaranichols@gmail.com

Now, however, Julia Nichols, Kara's mother, is revealing more about her daughter's activities. In an interview with KRDO-TV, she admitted that authorities feared that foul play was a possibility from the beginning "because of her issues with drugs and the link to prostitution."
