Police found bottles of prescription codeine and a large amount of marijuana on the plane carrying rapper Jarad Anthony Higgins, also known as Juice WRLD, shortly before he died Sunday.

Police and FBI agents arrived to meet Higgins’ plane at about 1:30 a.m. CT at Midway Airport on Sunday on the suspicion the rapper was in possession of contraband, the Chicago Police Department said Monday. Officers found 70 pounds of marijuana and six bottles of prescription codeine cough syrup in a search of the luggage on the twin-engine Gulfstream jet.

There were also two 9 mm pistols, a .40-caliber pistol, a high-capacity ammunition magazine and metal-piercing bullets found on the plane, according to police.

Though circumstances leading to the 21-year-old rapper’s death are still unclear, police said Higgins began convulsing while police officers were speaking to him and others on the plane. He was given two doses of Narcan, a brand of naloxone used to block the effects of opioid overdose in emergency situations.

Higgins woke up briefly but was later declared dead at a local hospital.

The Cook County Medical Examiner’s Office said Monday it must conduct more tests in Higgins’ autopsy to determine the cause of death, including cardiac pathology, neuropathology, histology and toxicology testing.

Christopher Long, 36, and Henry Dean, 27, two guards who were with Higgins at the time, were arrested on unrelated gun charges, according to the Chicago Police Department. Arrest records for the men are not available and it is unclear whether they have attorneys.

Dean allegedly told police he had two guns and a high-capacity magazine on him at the time. A third gun was found in a camera case among Long’s possessions, though he denied owning it, according to police.

Higgins, a Chicago native, was signed to Interscope Records and considered at the forefront of the emo rap scene. He released a collaborative album in 2018 with Future before releasing his debut record, titled “Goodbye & Good Riddance.”
