A former Lincoln Public Schools bus driver has been sentenced to 100 days in jail for inappropriately touching a 17-year-old special-needs student.

David Kraegel, 64, was sentenced Wednesday in Lancaster County Court. In August, he pleaded no contest to third-degree sexual assault.

Police say Kraegel was dropping off the girl in June when a couple in the area saw Kraegel and the girl embracing. The couple told officers they boarded the bus and asked the girl if she was OK. Kraegel said he had been helping the girl crack her back. The couple called police.

The girl told authorities that Kraegel had kissed and touched her.
