Alexander Lewis Sannella Centeno, 21, was shot to death inside his Stockton home in the 5400 block of Holiday Drive on February 18, 2013. A lifelong Stockton resident who attended Lincoln High School and enrolled at Delta College, Centeno’s death was described by police as resulting from the negligent discharge of a firearm rather than a premeditated attack.

Stockton Police arrested a friend, 19-year-old Andrew Torres, in connection with the shooting. Prosecutors charged the case as involuntary manslaughter; Torres was later convicted and the court clarified his sentence in May 2014.

Centeno’s killing was one of many homicides in Stockton that year and prompted local discussions about firearm safety and violence prevention. If anyone knew Centeno or has information about the circumstances that night, please share what can help clarify what happened.
