Former Alpena Bus Aide Sentenced to Prison For Sex Crimes Involving Children

A former Northern Michigan bus aide has been sentenced to 20 to 30 years in prison after police say he sexually assaulted at least 10 young riders.

Andrew Bartz from Alpena was sentenced Monday for criminal sexual conduct stemming from assaults involving children ages 3 to 15 in 2014 and 2015.

Authorities say Bartz was an employee of Prell Services and worked as a bus aide on Thunder Bay Transportation Authority Buses helping special needs and preschool children in Alpena.

Bartz also assaulted a 3-year-old boy in Alcona County.
