The data shows that two men and two women were released in the Waterloo zip code. The median age of the parolees was 40. The youngest parolee was a 30-year-old man convicted of a property crime in 2017, and the oldest was a 53-year-old man convicted of a crime involving drugs in 2015.
The offender who had been incarcerated the longest was David Shelton. He was convicted of a crime involving drugs in 2015, when he was 53 years old. He is now 56.
Under state law, paroled offenders are still in legal custody of the IDOC, meaning they can be taken back to a correctional center at any time if the state has probable cause or a warrant.
