PHILADELPHIA (CBS) - A man is fighting for his life after he was gunned down in the city's Mayfair section following another violent weekend in Philadelphia. Gunfire erupted around 11 p.m. Sunday on the 3100 block of Barnett Street.

Officers found a 21-year-old man shot twice in the back, and rushed him to the hospital.
