The hip-hop world is mourning the sudden death of up-and-coming rapper Juice Wrld. The 21-year-old Chicago-born rapper, real name Jarad Higgins, went into cardiac arrest and died early Sunday after an apparent accidental overdose of Percocet.

Percocet is a Schedule II narcotic that contains Acetaminophen (Tylenol) and the opioid oxycodone (OxyContin).

Federal agents were waiting inside a private hangar at Chicago’s Midway Airport for the rapper’s jet to arrive at 1:30 a.m. Agents reportedly received a tip from the pilot that the plane was loaded with drugs.

A search of the plane turned up 41 “vacuum-sealed” bags of marijuana, six bottles of prescription codeine cough syrup with no labels, two 9 mm pistols, a .40-caliber pistol, a high-capacity ammunition magazine and metal-piercing bullets, law enforcement sources told The Tribune.

No one in the rapper’s entourage claimed ownership of the drugs and no charges were filed.

Higgins may have panicked and swallowed a handful of Percocets because the feds searched his private plane in November too.
