Milton Felder was sentenced Tuesday to 36 to 40 years after earlier pleading no contest to manslaughter and a weapons count in the May 2017 shooting of Brandon White.
Prosecutors say Felder and three teens had planned to rob White and another man during a marijuana deal when the shooting happened outside McMillan Middle School.
Another adult, 19-year-old Allana Smith, has also pleaded no contest to manslaughter and a weapons count. Two other teens charged as adults have pleaded no contest to lesser felonies. All three await sentencing.
