Coach accused of improper relationship with student

COLDSPRING, TX The teacher resigned late last month when the allegations first surfaced, but we've learned investigators are talking to more people, worried that there may be more students involved.

Dennis Isbell, 39, was a popular coach and teacher Coldspring-Oakhurst High School in Coldspring. Students were surprised to learn instead of being on the court, he was behind bars.

For years, students at Coldspring-Oakhurst High simply knew him as Coach Isbell. But last month, high school basketball coach and speech teacher Dennis Isbell resigned amid allegations of an improper relationship with a student. Many were surprised by the accusations.

"I'm shocked because this shouldn't happened in Coldspring," said John Dabney, Coldspring-Oakhurst High School senior.

"He's been there for years. He taught my brother," said Devin Todd, former Coldspring-Oakhurst High School student.

It all started back in November when Coldspring-Oakhurst Consolidated ISD began an internal investigation and place Isbell on administrative leave. By February, Coach Isbell resigned during the investigation and on Tuesday morning he was arrested in his Montgomery County home.

The lights were out at his home and no one answered tonight.

Isbell now faces at least one charge of indecency with a child by sexual contact.

"He's really logical and he thinks things through, but why he would slip up like this, I don't know," said Dabney.

The San Jacinto County District Attorney's Office told us their investigation continues and more charges may be filed as investigators think there may be more victims. We will continue to bring you the latest on Eyewitness News and here on abc13.com to let you know if any more students come forward.
