Andrew Turley, from Houston, faces charges of prostitution and trafficking a minor after allegedly prostituting a four-year-old girl on Craigslist.

He reportedly offered two hours with the girl in exchange for $1,000 through a "daddy's little girl" ad. A sting took place on Thursday where the 28-year-old father had allegedly drugged the girl with sleeping pills.

An officer from the Houston Police Department had discovered the ad in the Casual Encounters section on Craigslist.

For 10 days, the undercover officer exchanged 69 emails through November 12 with the person who posted the ad who claimed that "he had a young girl, younger than 10." The undercover officer and Turley then arranged to meet at an apartment complex.

When the officer arrived, the young girl was found lying under a blanket naked and in a "groggy state." Turley was taken into custody, and a bond has been set for $500,000 for each of the two charges. He is set to appear in court on Monday.

Prosecutor Ann Johnson said, "These are cases Harris County takes very seriously."
