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.

During his arraignment today, 24-year-old Cristhian Bahena Rivera pleaded not guilty to murdering Tibbetts.  Prosecutors charged Rivera with first-degree murder in August after he allegedly stabbed Tibbetts to death.  Tibbetts vanished while out for a run in Brooklyn on July 18.   The search for Tibbetts lasted for more than a month and drew national attention.   Police say on August 21 Rivera led them to Tibbetts’ body in a cornfield, but he told them he doesn’t remember killing her.  An autopsy shows Tibbetts died of several stab wounds.

The trial has been scheduled to begin at 9:30 a.m. April 16, 2019. He also waived his right to a speedy trial during the arraignment in Montezuma.  Rivera is currently jailed on a $5 million cash-only bond.

Authorities have arrested a 22-year-old man they say murdered a former Iowa State University golfer Monday morning at an Ames golf course near campus.  Ames police Commander Geoff Huff said at a news conference that officers were called just before 10:30 a.m. to the Coldwater Links golf course in the 1400 block of South Grand Avenue on reports of a suspicious circumstance. Golfers told authorities they found a golf bag with no one around it on the course. Officers found the body of Celia Barquin Arozamena, an Iowa State University student originally from Puente San Miguel, Spain, “some distance away.”  Officials said Arozamena had been assaulted and died as a result, though circumstances leading up to her death weren’t immediately clear. Police arrested Collin Richards, and he was charged with first-degree murder in connection with Barquin Arozmena’s slaying.
