Riley Strain remains missing

The toxicology report for Riley Strain – the University of Missouri student who vanished from a Nashville bar and was later found dead – has been completed by medical examiners in Davidson County, Tennessee, as family and friends of the drowned student cast doubt over how he died. 

The details of the toxicology report will be released with the complete autopsy, according to WSMV-TV. It's unclear when the ME will make the reports public.

The 22-year-old college student disappeared on March 8, during a trip to Nashville with his fraternity brothers. Strain and his friends were visiting country singer Luke Bryan's 32 Bridge Food + Drink when the bar staff "made a decision based on [their] conduct standards to escort him from the venue," the TC Restaurant Group previously said in a statement.

Strain's body was discovered in the Cumberland River on March 22 – following weeks of massive search parties and investigations.

Preliminary autopsy results showed his death "continues to appear accidental," with no signs of foul play, police said.

Strain's family had a private autopsy conducted in response to those findings.

Family friend Chris Dingman told NewsNation in March the first autopsy didn't find any water in Strain's lungs, suggesting he may not have been alive when he went into the river.

Dingman also claimed Strain wasn't wearing his pants or cowboy boots when he was found.
