GRAND PRAIRIE -- A Grand Prairie ISD teacher has been suspended while the district investigates a threat the teacher allegedly made in court while living in Oklahoma in 2013.

Christopher Durham, a STEM teacher at Grand Prairie Collegiate Institute, allegedly said he was “capable of doing things along the line of what just happened in Newtown, Conn.”

According to NewsOK, Durham’s threat was allegedly aimed at Oklahoma County Special Judge Lynne McGuire and attorneys Tom Daniel and Ken Klingenberg during a “contentious” divorce case.

More from NewsOK’s report:

According to a probable cause affidavit, Durham was distraught after learning his court case was “a lost cause.” He told his attorney that McGuire, Daniel and Klingenberg “do not realize what he is capable of and need to be careful,” a deputy sheriff reported.

Durham's attorney at the time told investigators Durham said he was “capable of doing all kinds of things and is capable of doing things along the line of what just happened in Newton, Conn.,” according to the affidavit.

Outside of court, Durham denied making any references to the school shootings.

“The charges are completely false, and I am confident I will be exonerated,” he said as he was led away in handcuffs and jail clothes.

In a statement sent to parents on Monday, GPISD said the comments Durham allegedly made “would be unacceptable in any part of society, and certainly unacceptable in a school setting.”

The district said it is investigating, and while that is ongoing, “Durham will be excused from all employment responsibilities.”
