William Jenkins, 66, died last month. He was 18 when he was paralyzed in the gang shooting.
Two teenage brothers served prison time then turned their lives around. George Lemus is now 64 and runs a computer repair business.
His brother, Robert, died a decade ago.
Lemus told The New York Times on Wednesday the new findings gave him goosebumps.
The district attorney will not prosecute further.
Samuel Jenkins agrees with that decision. He says his brother forgave the shooters.
