Unreleased Video of Missing Student Riley Strain Shows Him Walking Towards Bridge, Family Says

Strain has been missing since March 8 after departing a Nashville bar by himself

The family of Riley Strain has seen unreleased video of the missing college student walking towards a bridge, they tell PEOPLE.

"It was the last known video of Riley,” says his stepfather, Chris Whiteid. “It was good to see him.”

Nashville police showed the family the video on Sunday night. The footage of Riley near a bridge helped piece together his path, but where he went next is still unknown, he says.

“We’re looking for that next nugget right now, just trying to find that so that we can move forward,” Whiteid adds.

PEOPLE could not immediately reach the Metropolitan Nashville Police Department for comment.

Police have been slowly releasing footage of the 22-year-old University of Missouri student after he disappeared from a night out with his friends.

On March 12, police released footage of Strain stumbling and falling, and earlier this week, they shared body camera footage that showed Strain briefly interacting with a police officer who was responding to a vehicle break-in.

Strain “did not appear distressed,” when he encountered the officer, who was in the area while responding to “a vehicle burglary call,” police said on Monday. When asked how he was doing by the officer in the video, Strain replied, "I'm good, how are you?" before walking away.

In Tuesday's press conference, police said they released the video after getting multiple calls claiming that Strain was chased or being followed, which they say they've seen "no evidence of."

The officer's body cam footage was the last time the family heard his voice.

“That’s the last video we have showing him speaking,” Whiteid says. “It was rough to hear...But hearing him speak, we could hear him – he did not sound highly intoxicated.”

The footage has actually raised more questions for the family.

“That was kind of a double whammy,” Whiteid says. “It's like you wish that he would've been extremely drunk and the cop would've said, 'Hey, stop. Let's talk.' ”Or he wishes his stepson had spoken up and said, "Hey, I'm lost. Can you help me?"

“But he didn't,” Whiteid adds. “Listening to him, it was Riley. The way he addresses the officer, that's Riley. That's how he talks to people, and it gives you an insight to a little bit of our son in this horrible moment.”

In recent days, police officers have had a couple of phone calls with the family saying they’re following up all the calls and tips coming in, but there’s “nothing solid yet,” according to Whiteid.

“I feel that the Nashville Metro Police Department is doing everything within their power. I feel that they are overwhelmed with the amount of information that's coming in due to the social media and the news coverage that we've been fortunate to have and so it's a double-edged sword," he says. "I have my days that I'm frustrated. I have my days that I know they're doing everything they can. It's like I tell everybody: Put yourself in that position. If this was your family member they were missing, how would you feel? It doesn't matter how fast it's done, it's not going to be fast enough.”

“If you can see your son two blocks away from you and they're bringing him to you, you don't want to see him two blocks. You want him two inches from you. You can't get there quick enough," he adds. "It's never going to be quick enough for family, no matter how many people are working on it. So, I try to remind myself of that. I try to remind my family of that, and we just take every day, hour by hour and see what we can do.”

Right now, they’re still searching everywhere, and waiting.

“We’ll see what tomorrow brings,” he says.
