Houston police are searching for people who may have had contact with a convicted sex offender accused of raping two girls, infecting them with HIV and other sexually transmitted diseases. Wilson has been a registered sex offender for life since 2004, after he was convicted for sexually assaulting another 14-year-old girl, according to the Texas Department of Public Safety sex offender registry. A judge may require registered sex offenders to avoid being around children, according to the Texas Department of Public Safety website.
