The autopsy of University of Missouri student Riley Strain has uncovered no evidence of "foul play-related trauma," police said Monday.
Strain's death, which was found in the Cumberland River eight miles from downtown Nashville on Friday morning, "continues to appear accidental," Metropolitan Nashville Police Department spokesman Kristin Mumford said in an email.
Mumford said police are still awaiting the medical examiner's toxicological test on the 22-year-old student. "The ME does not complete an autopsy report until all testing is back," he stated.
Police are investigating what happened to Strain. While attending a Delta Chi Fraternity spring formal in downtown Nashville, Strain was asked to leave Luke's 32 Bridge Food + Drink and went missing on March 8.
A week after his vanished, Luke's 32 Bridge + Drink reported Strain was served one alcoholic drink and two waters before being taken out by security at 9:35 p.m. "based on our conduct standards." The establishment did not elaborate.
Stepfather Chris Whiteid told NBC News affiliate WSMV that Strain promised his buddies he would return to his hotel before leaving. In an interview on "Top Story with Tom Llamas," Whiteid said Strain never returned to the hotel.
After leaving the bar, Strain appeared to stagger around downtown and have a cordial conversation with a police officer, according to police videos. On March 17, his bank card was located between Gay Street and the river.
A worker at a West Nashville business found Strain's body after taking an object from the river two weeks after he disappeared and notified the authorities, Metropolitan Nashville authorities Chief John Drake said Friday. Drake said Strain's clothing and other identification helped the medical examiner's office identify him swiftly.
