Seven Bucks County residents, ranging in age from 13 to 57, are accused of downloading child pornography from the internet. Bensalem Police identify them as a 13-year-old Middletown girl, a 15-year-old Newtown Township boy, a 15-year-old Bristol boy, 18-year-old Tyler Miller of Middletown, 20-year-old Scott Drybala of Bensalem, 23-year-old Andrew Curry of Bensalem and 57-year-old Willard Harte of Warminster.  The minors’ names are being withheld because of their age.  The Bensalem Special Victims Unit has computer software that can track down people who are downloading child pornography online, finding the house and the computer within the house where the crime was committed.  Police say they were surprised to find the 13-year-old girl because of her age and gender, and her parents had no idea what she was doing.
