A Souderton man has admitted having child pornography. 57-year-old Dale Childress of Noble Street pleaded guilty to possessing child pornography and sexual abuse of children Monday in Montgomery County Court.  Pennsylvania State Police started looking at his activities in November of last year, when an undercover investigation into internet sharing of child pornography turned up pictures of sexual acts between an adult man and an underage girl on his home computer.  After searching his home and confiscating equipment in January of this year, they found numerous child pornography videos on his computer.
