A young Loveland, Colo. couple have been arrested after a disturbing plot to lure a man and his 6-year-old daughter to a motel for sex, only to rob the man and kidnap the child to raise as their own.

According to ABC News in Denver, Sareena Morrison, 18, and Dustin Canup, 20, arranged to meet a man at the Hi-Way Motel in Loveland  on Friday, where police arrested the couple.

The couple told police that they had put messages on a sex website targeting men who were willing to bring their children to the hotel and have sex with Morrison.

The couple informed the police that they had no intention of having sex with anyone, they were planning on robbing the man and kidnapping the child to raise as their own.
