Mark West, Texas Assistant Principal, Accused Of Having Sex With Student At Prom Event

A former assistant principal is facing criminal charges after allegedly having sex with a student in his office during a prom event last spring, Houston's KTRK-TV reports.

The news outlet previously reported that administrators at Spring High School had suspicions about Mark West prior to the allegations. Months earlier, the former assistant principal was accused of touching a student on her lower back and was ordered to refrain from physical contact with his students.

According to court documents obtained by KTRK-TV, West's secretary had also noticed female students spending an usual amount of time in West's office, often leaving with their hair disheveled.

It's been a rough month for Houston-area schools, which have had at least three other staff members facing accusations of inappropriate behavior in the past few weeks.

As the Houston Chronicle reported, 38-year-old nurse's aide Maria Calvillo was also accused of having sex with a student earlier this week. The student's mother is said to have found explicit messages from the woman on her son's Facebook account.

Similarly, Timothy Glenn, an ROTC instructor at Livingston High School, was arrested this week after he was seen allegedly sharing an intimate hug with a 14-year-old in a park, KHOU reports.

And as the Houston Press noted last week, a female student recently admitted she had sex with her dance teacher countless times. The girl was reportedly too embarrassed to tell anyone and said she hoped that graduating would get her away from the teacher. Now the Humble High School teacher, Amanda Feenstra, is facing felony charges of improper relationship with a student.
