When he wasn’t luring the kids off the playground, he hosted parties for them with alcohol and drugs, Whelan said.

Officials say Taussig-Lux would hold parties for students from the areas of Media Borough, Upper Providence, Middletown and the surrounding areas.

At that apartment on the 100 block of East Baker Street, Whelan said Taussig-Lux would play video games with the teens, while giving them alcohol or drugs, including cocaine or acid, and then he would force himself on them.

Taussig-Lux is currently incarcerated at Graterford State Correctional Institution. He was sentenced to 13.5 to 27 years in state prison, in addition to eight years of probation.

Authorities say he also faces a lifetime Megan’s Law registration.
