A Colorado mother is traumatized after a stranger broke into her house and took a single selfie on her phone before sneaking back out, Denver police said.

The unnamed woman was putting her children to sleep just before 9:30 p.m. when the bizarre incident occurred on Jan. 29 at her Denver home.

The mother told police she had no idea the man was in the house and only found the selfie on her phone the next morning.

Authorities are still on the hunt for the suspect and are offering a $2,000 reward for any information leading to his arrest.
