It’s been six months since a mass shooting at a child’s birthday party left four dead and at least 13 others injured in Stockton.

When reached for comment Monday, the San Joaquin County Sheriff’s Office said the investigation is ongoing.

There still have been no arrests in the Nov. 29 attack, which authorities have described as “targeted.

“We do not have any further information at this time,” spokesperson Keri Mayoya said. “Just please know that our agency is continuing to work diligently and bring the individuals responsible for this to justice.”

Two days after Thanksgiving, masked shooters entered an event center on Lucile Avenue in north Stockton where at least 100 people had gathered for a 2-year-old’s birthday party. In the months since the shooting, few new details have been released.

But there has been progress in the case. In February, sheriff’s investigators asked for the public’s help in identifying anyone connected to two sedans — one white and the other silver — believed to have been used by the assailants.

Officials say the shooters, dressed in dark clothing and face coverings, fired multiple rounds into the family gathering, killing three school-aged children and a young adult

At least 50 shots were fired from at least five guns, authorities have said. Killed in the attack were Maya Lupian and Journey Rose Reotutar Guerrero, 8-year-old cousins; Amari Peterson, 14; and Susano Archuleta, 21.

In his monthly address in April, Sheriff Patrick Withrow said investigators were “moving forward” and noted that the probe was “doing very, very well.”

At the time, he said there were a couple of months’ worth of electronic information — video, cellphone data and the like — that was being reviewed. Once the district attorney’s office is satisfied with the evidence, “that’s the time we’ll start putting handcuffs on people,” Withrow said. “We should have results here in just a couple months.”

The Sheriff’s Office has previously said it was not giving a deadline in the case.

Withrow warned in the weeks immediately after the attack that it was “going to be a long investigation.”
