Court documents from 15 court cases involving Collin Richards, the man accused of killing Iowa State University student Celia Barquin Arozamena, dating back to 2014 have been reviewed, many of them connected to violent crimes. Over the years some of the crimes Richards has been convicted of includes harassment, theft, and domestic abuse.  The harassment case stems from an incident in January 2015 where he threatened to shoot up a gas station in Guthrie County after clerks there claim they caught him trying to steal energy drinks. His sentence for the crime was 90 days in jail.

It was just a month later Richards found himself in front of judge again for stealing a car. The end result was a two year prison sentence suspended, so no time in jail.  Richards would be back in jail again in September 2016 after being convicted of stealing tobacco and beer from the same gas station he had previously threatened to shoot up. That again got him a suspended prison sentence and time served for 31 days in jail.  Richards most recent conviction is from July for public intoxication. He was ordered to pay a fine.  Richards was also on probation for several of these offenses but never was convicted of a probation violation.
