Search for missing Missouri student Riley Strain: Nashville cops scour river near where 22-year-old was seen stumbling around drunk after being thrown out of bar

Police boats are searching a river for signs of missing student Riley Strain who disappeared on a night out with friends six days ago.

Strain, 22, was last seen on Friday night after being kicked out of Luke's 32 Bridge Food + Drink, owned by country singer Luke Bryan, on Broadway in Nashville.

CCTV footage showed the University of Missouri student stumbling through the streets on March 8 near the Cumberland River.

The Metropolitan Nashville Police Department and the Office of Emergency Management are scouring riverbanks for clues using boats and sonar equipment.

Strain was reported missing by his Delta Chi fraternity brothers, who were in town with him for a fraternity conference, when he didn't return in the morning.

'Everyone right now is just holding their breath, hoping that we will find him safely, hoping that we will find him without injury,' University of Missouri spokesperson Christian Basi said. 

Police applied for a warrant to access his phone and Apple Watch data, hoping it would pinpoint his location or at least trace more of his movements.

A private investigation firm hired by Strain's parents is also searching for him. 

Strain was in Tennessee on a group trip for Delta Chi's annual spring formal when he was kicked out of the bar about 10pm because he was too drunk.

He told his friends he would just go back to the hotel, but instead walked in the opposition direction, looking confused and disoriented. 

Video from Downtown Smoke & Vape Shop on Church Street obtained by WKRN showed Strain near the intersection of 2nd Avenue and Church Street.

He was wearing a two-toned black and brown shirt and blue jeans and took a tumble, then quickly got back up and continued down the street.

Another camera caught near the intersection of Gay Street and 1st Avenue North just before 10pm taking large strides with his head down as he stumbled through the streets.

'We feel like when he came out, because they had been to a couple of other places, that he had got turned around on the direction,' Strain's stepfather Chris Whiteid said.

Additional surveillance footage released by the Nashville police show him wobbling and appearing confused as he crossed a closed road near the water. 

The next morning, his fraternity brothers tried to find Strain using his Snapchat location but were unsuccessful and called police to report him missing.

His last phone location was recorded between Gay Street and James Robertson Parkway close to the bar where he was last seen. 

Police attempted to locate his phone but have drawn a blank, while also checking local hospitals and jails.  

They conducted a helicopter search on Tuesday to scour the downtown Nashville area, including the Cumberland River. 

His mother Michelle Whiteid said he's 'a great kid' and normally 'very communicative'.

'We miss him and we want him back so bad,' she told WKRN.

'He's always texting me, calling me, FaceTiming me,' she added. 'He's always in touch with me. He's very communicative.'

Country singer Luke Bryan, one of the owners of the bar, said on Instagram, 'Y'all this is scary. Praying for his safe return.'

TC Restaurant Group, the operator and another owner of the bar, said it was 'continuing to work closely with the Metro Nashville Police Department to provide security camera footage and any other potentially helpful information to aid in the search for Riley Strain'.

In an appeal for information about Riley's whereabouts, Nashville Metro PD described him as '6'6", 165 lbs. with blonde hair and brown eyes.'

The University of Missouri said it had 'been in touch with the family and authorities in Nashville' who were working to find the student.

'The safety of our community is our highest priority,' Angela King Taylor, interim vice chancellor for Student Affairs, said.

'Our thoughts are with Riley's family as the search continues. We will be offering any support to them that we can, and we encourage anyone who needs help to reach out to our counseling resources.'
