PITTSBURGH — Twenty-one-year-old Miras Kelly II, faces 10 to 40 years in prison after he pleaded guilty Wednesday in Allegheny County to charges including third-degree murder, conspiracy, attempted homicide, aggravated assault and robbery. Prosecutors said he and another man broke into a McKeesport home in September 2017 and killed sisters Melodie Robb, 52, and Kimberly Lesko, 55.

Kelly testified last year against co-defendant Kylee Lankford, 21, who prosecutors said was the shooter.
