RICHMOND, IND. — Mary York is to be in court Oct. 8 to enter a plea to felony charges for her actions connected to the December 2019 incident at Dennis Middle School in Richmond, Ind., where her teenage son killed himself after exchanging gunfire with police.

The Richmond woman has agreed to a plea deal with the Wayne County Prosecutor's Office, according to online records.

York, according to an investigator’s affidavit, called police Dec. 13, 2019, to report that her son, Brandon Clegg, took her longtime partner by gunpoint and forced him to drive to the school. She told police he intended to kill students and himself. Inside the school, Clegg fired at police before he died by suicide. No one else was harmed.

The day before, Clegg videotaped himself saying he was going to kill people at the middle school on Dec. 13.

York turned herself in on charges that included one count of dangerous control of a child, four counts of neglect of a dependent and one count of criminal recklessness.

Investigators allege York took Clegg out of hospital treatment after 10 days in May 2018 “because her insurance would not cover the cost of treatment and she could not afford it,” even though the boy said during intake he “wanted to go to the school and kill the kids that bullied him.”

She told investigators “that she knew nothing about his mental health diagnosis or what was said during his intake evaluation,” though staff at the hospital told investigators they met with York on several occasions and spoke to her by phone.
