On October 24, 2017, Hribal, then 20, pleaded guilty in the Westmoreland County Court of Common Pleas to 21 counts each of attempted homicide and aggravated assault. Defense attorney Thomassey said that the Hribal family wished to spare victims from having to testify and relive the attack at trial. The plea came after Judge Feliciani denied the defense's requests to allow Hribal to plead guilty but mentally ill. District Attorney John Peck stated that he planned to push for a prison sentence of 30 to 60 years, while Thomassey said he will argue for "as light a sentence as I can."
