Riley Strain's family invites Cajun Navy to look for their missing son

The University of Missouri student disappeared after a night out in downtown Nashville more than 10 days ago.

The search for Riley Strain continues in downtown Nashville. The University of Missouri senior disappeared after a night out on the town more than 10 days ago. Now his family has asked a search and rescue team to come assist with the search.

Police from the Metropolitan Nashville Police Department are once again searching the Cumberland River and homeless encampments near the river. The Cajun Navy will begin their searches later this week. The Cajun Navy usually helps disaster victims after hurricanes and other storms. However, Strain's family contacted them to help find their son.

Strain went missing on Friday, March 8, after he was kicked out of Luke Bryan's bar on Lower Broadway. Since then, the bar has said it only served him one drink and two waters. Surveillance video of Strain shows him wandering around downtown Nashville, stumbling and eventually hitting his head on a pole and bouncing off of buildings. On Monday, Metro Nashville police released a new video of a very brief interaction between an officer and Strain. Strain answered he was doing OK.

The only physical evidence police have in the case is Strain's debit card found along the Cumberland River by a pair of women wanting to help the case. Police iterated again on Tuesday there has been no evidence of foul play.

"We feel we need the extra resources as we try to get more organized for our family and bring more clues to light," Strain's stepdad Chris Whiteid said. "We are very grateful for everyone that has done everything so far. We ask that you work and help us as we become more organized. We don't want individuals out there alone without us knowing. We appreciate more than you'll ever know about the outpouring we have received. Our goal is still to bring Riley home. We feel that is still a pliable goal."
