Maureen Horkan, director of the Child Predator CyberCrime Unit, arrives on the scene and tells Lisa that pornography was being downloaded on a computer inside the home when the officers arrived.

"We have flat-out child pornography," she says. "[It's] child pornography that includes sexual conduct. Sexual conduct means penetration, means rape of children, means bondage with children. ... It can be some of the most horrific stuff."

After further investigation, the officers name the homeowners' 18-year-old son, a high school student, as their prime suspect. Officers pull him out of school and bring him home for questioning.
