Police in north Texas are searching for a serial bank robber who's held up six banks in four cities in four months.
Even with substantial video and pictures of the suspect, some of the best minds in law enforcement still have no clue who he is.
They're calling him the "Handsome Guy Bandit".
He's named for his disguise, the Handsome Guy mask, an $800 special effects mask that looks, moves and feels like real skin.
"It's really hard to tell that there's a person underneath it and it's not the actual person's face," says Kevin Perlich of the Richardson, Texas Police Department.
The torso part of the mask conceals his true size.
He can change the look from business to casual, glasses to sunglasses.
He can even add facial hair.
The disguise has worked at six banks.
"Well it's certainly escalated the crime from where it was just a note passing before to now you know he is armed. He's obviously had success with it so more than likely he's going to continue with it," Perlich says.
