NEW YORK (AP) — A once-rising rapper has been convicted of a 1993 New York City killing after recently telling police he’d shot someone while trying to rob him years ago.

Jurors delivered their verdict Tuesday in G. Dep’s murder trial. The rapper, born Trevell Coleman, faces at least 15 years in prison.

Defense lawyer Anthony Ricco says the rapper remains convinced he did the right thing by coming forward.

The 37-year-old rapper went to a police station in December 2010. He said he’d fired at someone on a Harlem corner when he was about 17 to 19.

Authorities paired his account with the 1993 death of John Henkel. But Ricco questioned whether police made the right match.

G. Dep gained attention with “Special Delivery” and “Let’s Get It” in the early 2000s.
