WICHITA, Kan. (AP) — The safety supervisor for the Wichita school district has been charged with multiple sex crimes stemming from a decade-old case police have been investigating for more than a year.

The Wichita Eagle reports 51-year-old Alex Robinson was charged Thursday with eight sex crimes, including sodomy and indecent liberties with a child, involving three victims ranging from 11 to 14 years old at the time of the alleged crimes.

Robinson worked for 22 years as a Wichita police officer and is a youth mentor who received presidential recognition for his volunteer work. He was taken into custody Wednesday in Wichita, and his booking charges also include being a fugitive from justice.

Robinson’s attorney says the investigation was still at an early stage and his client should be presumed innocent.
