A nine-year-old boy who underwent an outpatient tonsillectomy died Friday, according to the Milwaukee County Medical Examiner’s Office.

Solomon Womack went to the Children’s Hospital last week for the tonsillectomy and went home the same day. According to the Associated Press, Womack had been given a dose of Oxycodone at the hospital.

As instructed, his parents later gave Womack another dose when he returned home. He later had trouble breathing and was unresponsive which led his parents to call 911 and later rush him back to the hospital.
