DENVER — A man was sentenced Friday to 40 years in prison after pleading guilty to the fatal stabbing of a teenager, according to the Denver District Attorney's Office.

The DA's office said 20-year-old Auviauntea Evans pleaded guilty in July to second-degree murder in the death of 17-year-old Reese Grant-Cobb. 

The stabbing happened on July 1, 2018 during an altercation between Evans and Grant-Cobb near 571 E. Colfax Ave. in Denver.
