LOUISVILLE, Ky. (WHAS11) -- More details have been uncovered about the man allegedly looking at child porn at a Louisville public library branch.
On Monday morning Mark Brown, 37, faced a judge after police arrested him Sunday night at the Bon Air Branch Library.
We've learned that Brown is a convicted sex offender who previously worked in positions of trust...as a teacher, a teacher's assistant and a camp counselor.
While he was on parole, police say he obtained child pornography and looked at it in front of dozens of people at the Bon Air Library.
A convicted child predator is now back behind bars.
Mark Louis Brown was arrested for allegedly bringing a thumb drive containing child pornography into the Bon Air Library.
“He was using a computer that's used for word processing and for looking things up in the library,” said Louisville Library Director Craig Buthod. “It's in an area that's in view of library staff were paying attention.”
It wasn't Brown's first arrest on sex charges.
He was charged with 19 felony sex counts involving two teenage boys in 2004, when Brown was a special education teacher's aid at Atherton High School.
His court record indicates he also worked as a teacher at The Friends School and as a counselor at a boys camp.
Brown gave the boys at Atherton High School money and bought them presents in exchange for the boys participating in sex acts.
He described the relationship to WHAS11 news at the time.
“From my point of view, we maintained an intimate relationship for a year and a half,” Brown said.
Both victims told police Brown belonged in jail.
One boy even said he was “depressed to the point of suicide” and “scarred forever."
“If they contact me and for some reason need my presence in their lives, I'll be then glad to keep it going,” Brown said in 2004.
Brown pleaded guilty to those crimes.
“I pledge to you that I will not involve myself in a situation again in which a boy or anyone suffers because of me,” Brown said at his September 2004 sentencing hearing.
Brown was released in 2010 after serving only 5 years, 3 months of a 16-year sentence.
“It's the world we live in today. It doesn't surprise me anymore,” said library patron Tyler Whitaker.
Brown lives with his parents at their east end home,. two blocks from an apartment complex with a playground and dozens of children.
Nobody answered the door when WHAS11 went to the home. We asked Brown for another interview , but he declined our request.
Brown is due back in court on October 11.
