School custodian among 4 indicted in child sex crimes sting in Phoenix

A school custodian and a maintenance worker at a children’s group home are among four men indicted for child sex crimes.

Arizona Attorney General Mark Brnovich announced the indictments Thursday.

The indictments came as a result of an undercover sting called “Operation Summer Shield.”

The defendants are accused of soliciting sex from undercover agents who were posing as minors on various social media apps and websites.

Brnovich says that Ryan Kille, Luke Ottmann, Alex Waldron, and Andrew Herrington are accused of attempting to lure minors for sex by using the internet.

They are also accused of arriving at undercover locations to complete the alleged sex acts with those who they believed were minors.

At the time of Ottmann’s arrest, he was employed as a custodian at Neely Traditional Academy for Gilbert Public Schools.

At the time of Herrington’s arrest, he was employed as a custodian at Sunshine Residential Homes, which is contracted with DCS to provide group homes for approximately 300 children in the West Valley.

Operation Summer Shield was conducted over a week-long period and was the result of a joint multi-agency investigation by the Tempe Police Department, the Mesa Police Department, Homeland Security Investigations (HSI), and the Arizona Attorney General’s Office.

Ryan Kille, 32, is charged with luring a minor for sexual exploitation and attempted sexual conduct with a minor.
