(NewsNation) — Nearly 31,000 people have signed a petition that would require downtown Nashville bars to call cabs so that intoxicated people can get home safely.

The petition is in honor of University of Missouri student Riley Strain, who was asked to leave Luke’s 32 Bridge, a bar on Broadway, in Nashville, Tennessee.

“This law would make bars and staff mandatory to call cabs and ubers for intoxicated & disoriented individuals. Lets not let Riley’s tragedy end in vein. Please keep his family in your prayers and help keep our kids safe,” the petition reads.

Strain disappeared March 8 during a trip to Nashville with his Delta Chi fraternity brothers.

He communicated with his mother throughout the trip and texted her when they arrived at the hotel, she said. During the evening, Strain texted his mom, saying he ordered a rum and Coke “that didn’t taste good.”

The TC Restaurant Group, which owns and operates the bar, said Strain was asked to leave after being served one alcoholic drink and two waters.

His toxicology results aren’t complete yet. And it’s unclear what else, if anything, may have been in Strain’s system at the time.

The next morning, when Strain’s mom woke up to go grocery shopping, she received a call from his fraternity brother, asking if she’d heard from Strain.

His body was discovered two weeks later, about eight miles from where he was last seen. Strain was missing his wallet, pants and boots. His family said he had been wearing a belt that night, which should have secured his pants.
