MARSHALL, Mo. - Paul Chang's stay at jail was short. However, next time, it could be much longer.
The 61-year-old paid a $15,000 bond to leave the Saline County Jail Tuesday evening.
Chang was charged with two counts of sexual abuse and two counts of sexual contact with a student by a teacher, employee, contract employee, school official or volunteer.
The maximum penalty for Chang is 22 years in the Missouri Department of Corrections.
He did not answer his door in Blue Springs when 41 Action News Reporter Beth Vaughn knocked Wednesday afternoon.
Several miles away from his suburban home, Chang works as a sensei at the Blue Springs Aikido. The facility was empty Wednesday afternoon.
Sometime between Tuesday evening and Wednesday morning, the Aikido website and Facebook page were taken down.
Chang could have had unlimited access to a number of children at the facility.
In fact, when he admitted to undressing and inappropriately touching a 19-year old student at Prairie View State School in Marshall, he said there had been other instances as well. He worked as a physical therapist there. However, Chang did not disclose to police with whom or where the sexual touching happened.
Because of that, police want parents in Marshall and Blue Springs to have serious conversations with their children.
If your child had contact with Chang and you suspect inappropriate touching or behavior, call the Missouri State Highway Patrol at 816-622-0800 and ask for Sgt. Darron Blankenship. He is collecting information and handling potential victims.
Residents in Marshall were upset by the allegations, Chang's admission and the charges. No one wanted to speak on camera regarding the case.
The Department of Elementary and Secondary Education wrote, "The Department of Elementary & Secondary Education is aware of this incident, and we are fully assisting police with their investigation. Such employees are subjected to a background check every year, and Mr. Chang passed his background check in November 2011. The school is currently out for the summer."
