LaShawn Simmons, a 41-year-old former middle-school math teacher in Pasadena, is facing a slew of charges in connection with her having sex with four students, police say.

Simmons, who has resigned her position at the Pasadena district's Beverly Hills Intermediate School, is charged with sexual assault of a child, two counts of improper relationship between an educator and a student, online solicitation of a minor and possession of child pornography, according to court records.

The records indicate the teacher and students exchanged dirty texts and inappropriate photographs until a parent discovered what was going on. A two-month investigation showed, cops say, that Simmons had sex with four students at PISD's Dobie High: Two adults and two minors, all males.

Among the chats discovered by investigators was one allegedly from Simmons to one of the defendants, an adult: "That's my favorite," she allegedly wrote. "Ima make you cum fast with my mouth. Then swallow everything you give me."

Simmons has been a PISD teacher for 14 years.

Anyone with information on this case is asked to contact Trae Morris, a detective with the Pasadena ISD Police Department, at 713-740-0063.
