Authorities say Deffner died due to a self-inflicted gunshot wound.

According to the Norman Transcript, Young was representing Patterson in divorce proceedings with Deffner.

Patterson was reportedly granted a protective order against Deffner in July 2015.

Dr. Joe Siano, superintendent with Norman Public Schools, released the following statement regarding the death of Young:

“We are deeply saddened by the loss of Bryan Young, a former principal at Norman North High School, who was a tremendous asset during his time in our district.
