Sioux Falls Argus Leader reported that a workout in May 2021 at Lemke's Fitness and Training in Hartford, where Joel coached, marked the first instance of inappropriate sexual contact.

According to the report by the Sioux Falls Argus Leader, in October 2021, when the victim sought treatment for an ACL injury, Joel started texting her, asking about her family and boyfriend.

KSLA reported that the victim informed them that Joel started to plan her chiropractor appointments, specifically at slots when his administrative assistant was not present.

As per the report by the Sioux Falls Argus Leader, Joel asked the victim not to reveal his actions to anyone and destroy his life and career, justifying them as beneficial for the victim’s rehab and recovery from her injuries.

The Sioux Falls Argus Leader reported that according to the victim, between the end of April 2022 and the end of February 2023, she and Joel had inappropriate contact approximately 100 times, and no chiropractic work was performed at the later appointments.
