Montgomery County library employee accused of possessing child porn

CONROE, TX (KTRK) -- A library employee in Montgomery County is behind bars after authorities say he tricked underage girls across the world into sending him naked photos of themselves.

Timothy Alcala is charged with possession of child pornography. He was arrested August 22 after the images were discovered at a computer at his home.

Alcala is being held on a $1 million bond now, but investigators say for four years, he's tricked thousands of kids around the world into sending him naked pictures of themselves.

"If he found a victim in Australia or Conroe, doesn't matter to him because he got what he wanted from them," said Warren Diepraam, special prosecutor for the Montgomery County District Attorney's Office.

Investigators say Alcala's victims are mainly between nine and 14 years old and a simple click away. He'd scare them by saying he would tell their parents he had sex with them if they didn't send him the nude photos.

"And the kids felt very threatened by that, and unfortunately a lot of kids did send him pictures of themselves rather than reveal to their parents," Diepraam said.

Alisha Jackson and six kids, the oldest 13.

"She changes my Facebook password so they all know the password. They go through the people I'm talking tom ,y messages and all," her daughter, 13-year-old Kaitlyn Mitchum said.

That's exactly what experts say you should do.

• Keep computers in public area at home
• Install parental software
• Monitor the computer

"I understand that she's trying to keep me safe and away from these kinds of things," Mitchum said.

Alcala worked for the Montgomery County library system delivering books, but didn't directly interact with kids or use county computers.

"We don't have any named victims from Southeast Texas, but we do believe that there were victims from this part of Texas," Diepraam said.

Detectives believe Alcala was reaching out to girls various fake Facebook accounts, including Steven Wilson, Scott Williams, Vince Evans, Beth Dahl, Amber Dahl and Nick Wallace.

"That's why I said you have to tell me if someone is doing this to you, someone's messaging you and asking you for nude photos -- or any kind of photos," Jackson said.

Anyone who thinks Alcala may have interacted with their children is asked to contact authorities. Detectives think there are many more victims out there.
