On February 28, 2012 the Pflugerville Police Department received information that Lopez had an improper relationship with two male students, ages 14 and 13. Lexington ISD Police Chief D. Mohr had received an outcry statement from one of the victims after the victim requested his assistance in stopping Lopez from texting him repeatedly. Interviews were conducted on both victims and other persons who possibly had knowledge of the incident.
The investigation revealed that on February 11, 2012 Lopez contacted one of the victims via text message. She then drove to a residence in Pflugerville where both victims were staying. Lopez arrived with condoms and engaged both victims in sexual intercourse.
During the course of the investigation, approximately 1100 text messages were also documented that detailed conversations between Lopez and the victim before and after the incident.
After the incident, Lopez resigned from her position with Lexington I.S.D. Warrants were issued for Lopez on March 14, 2012 for two charges, Improper Relationship Between Educator and Student - 2nd Degree Felony— Bond $ 50,000, and Aggravated Sexual Assault—1st Degree Felony—Bond $50,000. Lopez was booked in Travis County.
Superintendent of Schools at LISD, Dr. Frances McArthur, said, “ At present, there is no information to suggest that any other students were involved, nor that any of the improper conduct occurred on campus. Parents can be assured that the safety and wellbeing of our district students remains our utmost priority, and that Lexington ISD’s mission remains focused on providing to our students the best educational environment possible.”
