The child had a tonsillectomy on Feb. 9 at an outpatient surgical center and was given a dose of Oxycodone, then sent home. Later that evening, Solomon’s parents gave him another prescription dose of Oxycodone and noticed about an hour later that he was having trouble breathing.

The parents called 911, and the boy was brought to Children’s Hospital. He was pronounced brain dead days later.
