The Delaware County Daily Times reports Nineteen-year-old Tristin Fisher pleaded guilty to third-degree murder Friday in last year's shooting death of 18-year-old Mohamed Kamara.
Judge Frank Hazel immediately sentenced him to 20 to 40 years in prison.
Authorities say Fisher shot the Penn Wood High School senior in East Lansdowne in April 2010 after a fight involving one of Fisher's relatives.
That man, 20-year-old Devon Ellis, faces charges including robbery and aggravated assault.
Kamara's family says he was looking forward to college.
