Riley Strain missing: New police video of teen

New police body camera footage released by the Metro Nashville Police Department on Monday shows an officer greeting Riley Strain on the evening of March 8 just before he disappeared. Strain, a 22-year-old senior at the University of Missouri, vanished that Friday evening after a night out drinking with friends during his fraternity's spring formal trip to Nashville. "No evidence of foul play has surfaced as work continues to locate Riley Strain," MNPD said in a Monday tweet. "On Sunday evening, Riley?s parents met with some of the detective team and received a full briefing on the work being done. They were also shown available video."
