A teen who police say admitted to fatally shooting a man and importing heroin has entered a not guilty plea to the charges against him.

News outlets report that 18-year-old Timothy Ganther Jr. was arrested Monday in connection with the Sept. 3 death of 28-year-old Jerome Wadsworth, of Michigan, who was found in a ditch in Lexington and later died at a hospital.

Lexington police Sgt. Jervis Middleton says Ganther and Wadsworth were acquaintances who had been in an argument.

Court documents say Ganther had admitted to intentionally shooting Wadsworth, as well as importing more than 100 grams of heroin from Ohio to Kentucky with intent to sell. On Tuesday, Ganther pleaded not guilty to murder, importing heroin and trafficking in a controlled substance.

He's been assigned a public defender.
