Missing Mizzou student Riley Strain's last known communication was reportedly a nonsensical message to his girlfriend.
Strain, 22, was visiting Nashville with other members of his fraternity when he was kicked out of Bryan's Luke's 32 Bridge bar on March 8.
At some point in the evening, he communicated with his girlfriend.
Chris Dingman revealed details of the text on NewsNation's Elizabeth Vargas Reports.
"She texted him to see how he was doing, if he was having fun," Dingman said. "He sent kind of a scripted text back to her saying 'Good lops'."
Dingman described the message as "unclear slang." He said the girlfriend didn't understand what it meant and did an online search to try to figure out its meaning.
He says the police took the family to view the recently released police video and some more videos. Those videos included footage from inside and outside the bar, all the way to the police body cam footage of an interaction with Riley.
He says several businesses volunteered footage from along the route he walked to help fill in a few pieces along the way.
"We now have a larger visual timeline to go with the digital tracking one we had," Dingman said in a Facebook post.
He said Riley had tried to go across the street to another bar and was declined entry. That's when he started his walk which ended in his disappearance.
Dingman also revealed that there have been no verified parts of Riley's clothing found.
Surveillance footage shows the visibly intoxicated student walking near the Cumberland River. At one point Riley ended up at a homeless encampment.
A man who believes he saw him shortly before he disappeared said that Riley caused a "commotion" inside his encampment, according to a report.
Riley's debit card was also found in that area.
Dingman also called it "curious" that his debit card was not covered in dirt or even dusty when it was found.
Dingman finished his post with a message for people who have tried to help, "Thank you sincerely from each and every family member. We truly appreciate everything everyone is doing and please, let's find Riley."
Strain is 6-foot-5, 160 pounds, with blond hair and blue eyes. He was wearing brown boots, jeans and a black-and-white shirt the evening he disappeared.
