Houston police say sex crime charges have been filed against a man who was a scout leader with the Boy Scouts of America in the Spring area.

HPD says Ulf Gerrit Lueders, 41, is charged with continuous sexual abuse of a child and online solicitation of a minor. He has since been released on bond.

“You’d never know that a neighbor like that, after knowing him for 15 years, would do something like that,” said former neighbor Nella Galindo. “That’s crazy. That’s crazy.”

Vincent Roth, Assistant Scout Master of BSA Troop 111, knew Lueders well. He says he never had any indication the scout leader could possibly be a pedophile.

"He liked his power as being a scout master,” Roth said. “But they never saw anything of a sexual nature come out of him at all.”

Roth says Lueders had been active in the troop for many years but left about one year ago. He says BSA performs background checks on adult participants, but they are not fool-proof.

“With background checks, you don’t know until somebody does something,” Roth said.

Roth earned his Eagle Scout rank about 30 years ago. He says the allegations strike a familiar chord.

“Years and years and years ago, actually my scout master got arrested for molesting a kid, so I’m very sensitive to that," Roth said.

According to HPD, Lueders was involved in the Boy Scouts of America's Sam Houston Area Council and was associated with Troop 111, Ship 846 and Crew 762, which are located in north Houston.

“Investigators believe there may be additional victims and are asking anyone whose children had interaction with Lueders to speak with their children,” HPD said in a press release.

Anyone with information regarding additional victims or whose children who may have had contact with Leuders is urged to contact the HPD Special Victims Division at (713)-830-3254 or Crime Stoppers at (713)-222-TIPS.
