STOCKTON, Calif — There have been 22 murders in Stockton in the first five months of 2019. There were a total of 33 murders in Stockton for 2018.

After a 34-year-old man was shot and killed May 4 during a vigil for a man killed a week prior, the Stockton Police Department assigned additional patrols in the area in an attempt to prevent further incidents.

“Enough is enough,” said Officer Joe Silva, spokesperson for the Stockton Police Department. “We need to bring some type of relief to this area and the police. We can’t do this alone.”

Stockton Police Chief Eric Jones told ABC10 that the department has reached out for assistance from partnering agencies such as the Bureau of Alcohol, Tobacco, Firearms and Explosives, the California Highway Patrol, and the FBI to curb the increase in murders.

"We need more tips. We know there are individuals in the community out there that know a lot about these cases or at least something," Jones said.
