Former Hancock Center worker pleads guilty to child porn charge

A man who once worked at the observation deck of the former John Hancock Center faces significant prison time after pleading guilty Monday to a federal child pornography charge.

Christopher Colon pleaded guilty to one count of receipt of child pornography, a charge carrying a mandatory minimum sentence of 15 years in prison.

Colon admitted receiving child pornography through messaging software on his computer on Sept. 22, 2017. He also watched child pornography with an unnamed individual in a Walmart parking lot in Skokie the next day, and received additional child pornography on Sept. 24, 2017.

Law enforcement targeted Colon in an undercover 2017 sting in which he offered free rides on the former Hancock building’s Tilt attraction, records show.

Posing as the father of two boys, 10 and 12, an undercover law enforcement agent responded to a Craigslist ad allegedly posted by Colon titled “Into perv/taboo chat, yng, fam (Chicago).”

In online messages that followed, Colon allegedly asked the agent, “Wanna meet just you and me, chat a bit and get to know each other? If we get along we can take it from there.”

Colon also allegedly told the agent he worked at the “observatory” and offered the purported father and his sons free turns on the “Tilt ride.”

In another exchange with an undercover FBI agent posing as a father with a 10-year-old son, Colon allegedly offered a free tour, drinks and snacks and a ride on the Tilt. He also allegedly said a private bathroom and office would be available “if you would like some special private time.”

A spokeswoman for the building has said in a previous statement that, “multiple background checks were run on the employee in question, and no negative information was returned.” Colon was convicted in January 2015 of aggravated child pornography in state court, federal records show.
