OKLAHOMA CITY - Investigators say one man had hundreds of images of child porn on both his cell phone and home computer and they say he was sharing it with others.

Members of the OSBI's Internet Crimes Against Children unit actually arrested the man at the airport as he made his way home. As it turns out, his roommate turned him in after finding child porn on his phone.

Investigators already had 31-year-old Billy "Blaine" Mayo on their radar, after they say he downloaded child porn from a file sharing network back in March. Police issued a search warrant on his home on Southwind Ave. this month and seized several computers phones and storage devices.

"I'm shocked actually," said neighbor, Randall Boyer.

Boyer lives right next door. He says he's concerned since several children live and play in this neighborhood.

"He needs to see the light and see what he's doing wrong," Boyer said.

But another neighbor, who not to be identified, says she's not surprised by Mayo's arrest.

"We always felt like something was going on down there," the woman said.

She says she often noticed Mayo dressed strange, and would not let her grandchildren anywhere near his home.

"There were times that we saw him in tights and a tutu and a cape. That just kind of sent an alarm, you know. And this wasn't at Halloween," said the woman.

Steve Tanner is with the OSBI's Internet Crimes against Children Unit and he says this is happening more and more often.

"There are literally hundreds of thousands of child porn images out there that are available for these people to share with each other. Some are manufacturing their own child pornography so they can share with other people...and it's things they've seen before," said Tanner.

Tanner says they do not believe Mayo was making child porn, but they are trying to identify the children found in the videos and photos on his phone and computer. He says the children in those photos and videos range in age from 5 to 14.

Mayo is being held on $30,000 bond. The OSBI says there could be more arrests in this child porn case.
