The (Chambersburg) Public Opinion reports that 19-year-old Adiel Sanchez Frometa was also convicted Thursday of robbery of a motor vehicle and theft.
Franklin County prosecutors said the Elizabeth, New Jersey resident stabbed 18-year-old Anthony Alfredo Hernandez in Chambersburg and stole his car in November 2016. Hernandez died three days later.
Frometa entered an open guilty plea earlier this year but withdrew it after a fellow inmate on trial for first-degree murder in another case was convicted of voluntary manslaughter.
Hearing testimony indicates that Frometa, who was 17 at the time, argued that he was defending himself after Hernandez resisted the theft of his car.
