By Wednesday, June 10, Casebolt had gone beyond the resignation to offer an apology, delivered by his attorney. She noted that Casebolt had been feeling emotional distress the day of the incident, having worked a suicide and an attempted suicide soon before getting called to the pool party dispute.
Casebolt was among officers called to the police party in Stonebridge, a planned community within McKinney. Accounts of what happened before and after differ, but a bystander's video captured him pulling his gun on black youth and throwing one black teenage girl to the ground.
