A Centennial High School teacher and football coach who was suspended last week resigned Friday amidst a growing police investigation.
Marcos Flores, formerly a Spanish teacher at the Williamson County high school, was suspended without pay on February 8.
Police would not say what their investigation entails, but the school system told Nashville's News 2 Investigates it involves inappropriate communications via social media involving Flores and a female student.
Sources added the high school student has transferred to another school
"The questions center around social media and we just want to emphasize we will be very careful how our teachers communicate through social media and we will continue to monitor this," Deputy Superintendent Jason Golden said.
According to the school's Web site, Flores graduated from the University of Tennessee in Knoxville.
He is reportedly married and was expecting a baby in October.
"We have had no issues with Mr. Flores from the time he was with us. He was with us as a teacher for two years," Golden said.
Efforts by Nashville's News 2 Investigates to reach comment from Flores were unsuccessful.
