OKLAHOMA CITY – A county jail inmate in Oklahoma who was a plaintiff in a lawsuit against the county accusing employees of torturing him and other inmates with a loop of the “Baby Shark” song died Sunday at the jail, the 14th death at the troubled facility this year.

John Basco, 48, was found unresponsive in his Oklahoma County Jail cell shortly after 3:50 a.m. Sunday, according to a media release from jail officials. Officers attempted life-saving efforts until emergency responders arrived and continued attempts to resuscitate Basco, the statement read.

Basco was pronounced dead at around 4:06 a.m., jail officials said. He had been booked into the jail Thursday on a drug trafficking complaint.

“One of the possibilities being investigated is that it was a drug overdose,” Mark Opgrande, director of communications for the jail, told The Oklahoman, part of the USA TODAY Network.

The state’s Office of the Chief Medical Examiner will make a final determination regarding the cause of Basco’s death. The Oklahoma State Bureau of Investigation will also assist with the investigation, jail officials said.

Officers charged with cruelty to a prisoner

In a case that attracted international attention, Basco and three other jail inmates sued the county last year after accusing two former detention officers, Gregory Cornell Butler Jr., and Christian Charles Miles, of forcing them to listen to loud repeats of the popular children’s song “Baby Shark” for extended periods of time while standing with their hands cuffed behind them to a wall in November and December 2019.

Former Lieutenant Christopher Raymond Hendershott was also sued for learning about the mistreatment but doing nothing to stop it.

The lieutenant retired and the two detention officers were fired after an investigation confirmed the inmates were subjected to the discipline in an attorney visitation room, in some cases as long as two hours.

Lawyers representing the detainees described the incidents as “torture events,” and the three officers were charged with misdemeanor counts of cruelty to a prisoner and conspiracy.
