Fifty-seven-year-old Sanford Kaplan has been released on bond. The Lincoln man is facing a variety of charges linked to allegations of child abuse.

Kaplan was formally charged on Thursday with six counts of false imprisonment, six counts of child abuse and two counts of Third-Degree Sexual Assault.

According to court documents, Kaplan has admitted groping his victims while they were bound and suspended from the rafters in a detached garage at his Lincoln home.

Lancaster County Sheriff Terry Wagner continues to urge possible victims to come forward.

He said Thursday, "We simply don't have the manpower to interview every child that Kaplan coached. So we really need the parents to determine whether or not their children have been victimized."

Kaplan had been teaching a geology class at Southeast Community College since early April. He was a part-time professor of geology at UNL, the boys soccer coach at Lincoln Northeast High School and a youth soccer coach for various organizations including the Capital Soccer Association.

Kaplan was released after posting 10 percent of $100,000 bond.
