As the search for Strain continues, News 2 retraced his last known steps to provide insight into his whereabouts.

According to TC Restaurant Group, Strain was escorted out of Luke Bryan's bar on the 300 block of Broadway on Friday, March 8. Records indicated that he had purchased one alcoholic drink and two waters during his time there.
