A former Texas high school teacher was convicted Friday after having sex with five 18-year-old students at her home.

It took the jury less than an hour to conclude that Brittni Nicole Colleps, 28, of Arlington, was guilty of 16 counts of having an inappropriate relationship between a student and teacher. The second-degree felony is punishable by two to 20 years in prison per count.

The Tarrant County jury convicted a former high school English teacher and sentenced her to five years in prison for having an improper relationship with five of her students, MyFoxDFW.com reported. She showed little emotion as the guilty verdict was read.

The teacher had sex with the students at her home over two months in 2011, authorities said.
Colleps is married and has three children. She turned herself in after a cellphone video of one encounter that involved multiple students emerged. That video was shown at trial.

Arlington police Detective Jason Houston testified that charges were filed because "18 or not, it's a crime" for a teacher to have sex with her students.

Two former students told jurors their relationships with Colleps began with the exchange of text messages that quickly turned sexual.

A 19-year-old testified that he had gone to Colleps' home twice with friends and they all engaged in sexual conduct.

A former student who is now 20 testified that he engaged in group sex and recorded his last encounter on a cellphone. He said initially the students spoke of the importance of keeping their activities quiet because they didn't want their teacher to get in trouble.
