Jose Nunez, a 32-year-old resident of Stockton, California, was shot and killed on October 4, 2016. He was found with gunshot wounds outside a residence on Madrid Drive at about 9 p.m., taken to a hospital in Modesto and later died. Police were called to the scene shortly after the shooting.

Investigators treated the killing as connected to another recent tragedy in the same family: Nunez was the uncle of 3-year-old Melanie Martinez, who had been killed by a stray bullet days earlier. Bullet holes were found in the garage of the home where Nunez was shot, and the circumstances suggested a possible drive-by. No suspects were immediately identified and a reward was offered for information leading to an arrest.

What information can anyone in the Stockton area share about movements or suspicious activity near Madrid Drive on October 4, 2016?
