Celina Victoria Ramirez, 22, was fatally shot on June 9, 2018, near West Lane and Knickerbocker Drive in Stockton. She had just attended a family graduation party and had recently received her high school diploma; her death was recorded as Stockton’s 15th homicide of the year.

Investigators say Ramirez knew the accused, 20-year-old Alexes Daniel Corrales, who was arrested within 48 hours and charged with her murder. Prosecutors linked the motive to Ramirez’s willingness to testify as a witness in another crime. At arrest, Corrales was held in the San Joaquin County Jail without bail while the District Attorney’s Office decided whether to seek the death penalty.

Court records show Ramirez had prior involvement in local cases: she pleaded guilty in 2016 to being an accessory after the fact with a gang enhancement and was jailed until May 2018. Records also connect her and the Corrales brothers to earlier trespassing and weapons-related incidents.

If anyone knew Celina or has information about what happened that night, please come forward.
