An Illinois teen has pleaded guilty to manufacturing and delivering heroin to a Beloit teen who overdosed.

Nineteen-year-old Johnathon M. Handy of Rockton, Ill., is scheduled for sentencing on July 10.

He is one of four teens charged in the Nov. 27 death of 18-year-old Ryan Kennington.

A criminal complaint says Handy helped 19-year-old Christopher Dorris of Roscoe, Ill., buy $90 worth of heroin. Dorris traded some of the drug to Kennington in exchange for a Starbucks gift card.

Eighteen-year-old Michael Maginnis of Beloit and 19-year-old Emily Hill of Winnebago, Ill., also have been charged in Kennington's death. A criminal complaint says Maginnis bought the heroin with Handy and Dorris. It says Hill used the drug with Kennington.
