A Happy Valley 18-year-old is answering some questions after his parent called police to report a home invasion and robbery Sunday -- but deputies say they have learned the "thief" was actually a prostitute.

One of Ethan Kwon's parents called police to their home near Southeast Mia Garden Drive and 152nd Avenue, according to the Clackamas County Sheriff's Office. Deputies learned $200 was taken from a bedroom nightstand.

The homeowner turned over surveillance video showing a woman walking casually through the front door into the house. Eight minutes later, she walked out and left.

Police on Monday said Kwon told investigators he was in his bedroom listening to music through headphones and he wasn't aware of anything suspicious.

But an update Tuesday afternoon from the sheriff's office said investigators found evidence indicating the initial report was false. No details were released.

Kwon "in fact invited the female seen in the surveillance video into the home," said Deputy Hayden Sanders. Kwon faces accusation of initiating a false report and patronizing a prostitute.

Deputies continue to look for the woman. This post will be updated.
