A woman who was once named “rookie teacher of the year” at a Florida middle school was being held on a slew of sex charges Tuesday after police said she molested a former student for about two months. Brittiny Lopez-Murray, 31, is accused of sexting a 14-year-old boy and engaging in sexual acts with him multiple times in her car while parked outside a mall, a pharmacy and other sites. The alleged victim, who is now in high school, used to be her student at Hialeah Middle School in Miami-Dade County.
