STOCKTON — Twenty-two-year-old Celina Victoria Ramirez may have been murdered as she waited at night along a north Stockton boulevard because she was willing to testify as a witness in another crime, according to charges presented in court Tuesday against the young gang member accused of killing her.

In addition, the San Joaquin County District Attorney’s Office believes that defendant Alexes Daniel “Mumbles” Corrales, 20, carried out the murder of Ramirez for the benefit of his gang. If convicted, he faces the possibility of death or life in state prison without the possibility of parole.

Corrales, who is being held in County Jail without bail, appeared before a judge Tuesday for his arraignment on numerous felonies, including suspicion of murder with three special circumstances: murder of a witness, discharging a firearm from a vehicle with the intent to kill and murder committed for a criminal street gang.

He did not enter a plea Tuesday. Instead, Superior Court Judge Ron Northup appointed the Public Defender’s Office to represent Corrales and scheduled further arraignment for June 26.

About 11:05 p.m. Saturday, Stockton police got a report of a person shot in a busy commercial corridor on the east side of West Lane between East Hammer Lane and Knickerbocker Drive. Responding officers found Ramirez on the sidewalk near Normandy Village. She was suffering from at least one gunshot wound to the head, according to authorities. The charge against Corrales implies that the shot came from a passing vehicle.

When medics arrived, they declared Ramirez dead at the scene, police reported.

Corrales was arrested Sunday afternoon about 10 miles south of the crime scene while driving on Arch Airport Road near Highway 99. The DA’s Office reported police found a shotgun in his car.

In September 2016, Corrales pleaded no contest — the same as a guilty plea — to a felony charge of willful discharge of a firearm in a grossly negligent manner and admitted to street gang activity, an enhancement to the charge. With that plea, two other charges were dismissed and Corrales was sentenced to 16 months with a condition that he register as a gang offender. His weapon was ordered confiscated and destroyed, according to court documents.

Ultimately, Corrales walked out of jail within hours of sentencing due to time already served. But the crime he was convicted of put one strike on his criminal record. If convicted of these latest charges, he would get a second strike, according to the DA’s Office.

In addition to the murder and special circumstances charges, some of the counts also leveled against Corrales include suspicion of intentional discharge of a firearm causing death, criminal street gang activity and two counts of being a felon in possession of a firearm (a 9mm semiautomatic handgun and a shotgun).

Authorities have provided no further information, including what crime Ramirez may have witnessed and details about Corrales’ gang affiliation.
