Extremely Violent

His girlfriend even said that Yust told her “I’ve killed people before, even ex-girlfriends out of sheer jealousy. I will kill you.” Yust ended up serving 120 days in jail after pleading guilty to these charges. But that wasn’t going to be the last time that authorities would have him in their clutches. It was obvious that his violent streak was not yet done.

Getting Arrested Again

Another few years passed, and Yust was once again charged with drug trafficking ‘designer drugs’ in November of 2013. And as if that wasn’t enough, Yust was also suspected to be involved in another missing person’s case, a girl named Jessica Runion. Yust was friends with Runion, and her boyfriend Jaxon Mallet, who was Yust’s friend from childhood. Allegedly, Yust was the last one to see the 21-year-old Runion alive.
