A Lansdale woman who admitted indecently touching a four-year-old girl has been given 11 1/2 to 23 months in Montgomery County Prison. 31-year-old Erica Dillon has already served more than 11 1/2 months, but she remains behind bars awaiting trial for allegedly having sex with a 14-year-old boy.  She is charged with indecent assault, corruption of minors and other offenses in that incident.  Police were called to her Walnut Street home in April for a report of a disturbance.  When they arrived the boy’s mother told them her son had sex with Dillon after she and her live-in boyfriend, 26-year-old Antonio Morano, watched a pornographic video with the boy.  He is charged with corruption of minors and other offenses.   Dillon was already a registered sex offender under Megan’s Law as a result of the incident involving the four-year-old girl.
