DES MOINES – An investigation is now complete into the finding in an Iowa prison of hundreds of capsules that contained an unknown substance.
The Iowa Division of Criminal Investigation Criminalistics Laboratory has completed the analysis on the 300-400 unknown capsules found at the North Central Correctional Facility in Rockwell City. All tests on the unknown capsules came back negative for any controlled substances.
The capsules were found during searches at the correctional facility earlier this month.
The capsules were sent to the Iowa Division of Criminal Investigation’s Criminalistics Laboratory in Ankeny for processing and analysis.
The North Central Correctional Facility houses about 494 medium and minimum custody inmates who have been classified low risk offenders, including misdemeanants and felons, which comprise approximately 80% of the population. The institution emphasizes individual accountability and responsibility. There are 107 staff in the facility.
