LAS VEGAS - Authorities in Las Vegas say a Utah teenager reported kidnapped in Las Vegas may not have been kidnapped after all.
Family members say 17-year-old Sarah Dunsey disappeared Jan. 15 while at the MGM in Las Vegas, Nevada.
Last week, Dunsey's mother offered up a heart-wrenching plea to the world to help find her daughter.
In a video posted to YouTube, the family claimed Sarah was a victim of sex trafficking and she was being held against her will.
Las Vegas Police have now confirmed to Fox 13 officers have no evidence Dunsey was kidnapped in Nevada.
Officers told Fox 13 Thursday afternoon Dunsey "was not kidnapped."
The department also said there's "no evidence any sex trafficking crime occurred."
Nevada authorities said the FBI has since taken the lead on the investigation.
The FBI has not responded to Fox 13's requests for information on the case.
Sarah's stepfather posted a message on Facebook about being "harassed" as a result of the family going public with their search for Dunsey.
