Haunting video offers new clues to Riley Strain's disappearance after 22 year-old frat boy vanished from bar before being found dead in the Cumberland River

New footage has offered fresh insight into the last known moments of 22-year-old Riley Strain before his mysterious death.

Strain's body was pulled from the Cumberland River two weeks after he vanished during a bar crawl with his fraternity brothers in Nashville on March 8.

And now video obtained by News Channel 5 shows the University of Missouri student being escorted out of Luke Bryan's bar after he was kicked out.

Staff had sent an alert about Strain being verbally abusive with the bar's employees. 

Strain appears to be unsteady on his feet as talks to the guard while they walk down the stairs from the roof top bar.

Officials have said Strain died from alcohol poisoning and drowning; his blood alcohol level was .228, three times the legal limit.

His system also had traces of Delta 9, a form of THC which is legal and readily available in Tennessee. The report deemed his death accidental.

The bar where he was kicked out of on the night of his death stated it had only sold Strain one alcoholic drink before asking him to leave.

The Delta Chi member was at the bar with his frat brothers on a trip for their annual spring formal when he was kicked out just after 9:30 p.m.

Strain had told his friends that he would meet them back at their hotel, but was nowhere to be seen when the group returned from their night out.

His friends tried contacting him, but received no response and they reported Strain as missing as they failed to locate him via his Snapchat location.

A massive search was quickly launched, with just small clues available to help investigators trying to find him, including finding his bank card along a riverbank and using surveillance footage to track his final moments. 

The mystery of his disappearance only heightened after chilling footage emerged of Strain stumbling through the city hours before his death.

Despite this, no camera captured his fall or put him in the vicinity of the Cumberland River where his body was found.
