(NewsNation) — Ballistics tests have linked the fatal shootings of six men and the wounding of one woman in California — all potentially at the hands of a serial killer — in crimes going back more than a year, police said.
The Stockton Police Department announced last week that five men have been slain in recent months, ambushed and shot to death alone in the dark. Late Monday, police said two additional cases last year — a man’s death in Oakland and the nonfatal shooting of a woman in Stockton — had been tied to those killings.
Police would not say whether all seven shootings had been linked to the same gun.
In the fatal Stockton cases, none of the men was robbed or beaten before the killings — which all took place within a radius of a few square miles between July 8 and Sept. 27 — and none appeared to have known each other, Silva said. The shootings also do not seem to be related to gangs or drugs.
The latest killing occurred shortly before 2 a.m. Tuesday, when a 54-year-old man was shot in a residential area just north of downtown, Stockton Police Chief Stanley McFadden said.
The other Stockton crime — in which a 46-year-old woman was shot but survived her injuries — occurred April 16, 2021, around 3:20 a.m., police said. The woman was also alone at the time.
The shooting death of a 40-year-old man in Oakland has also been connected to the violence in Stockton, police said. The man was shot to death around 4:15 a.m. on April 10, 2021. It was not immediately clear whether the man was also unaccompanied when he was killed.
The city of Stockton, Stockton Crime Stoppers and a local construction company owner offered a total of $95,000 for information leading to an arrest in the slayings.
Police released a grainy still image of a “person of interest,” dressed all in black and wearing a black cap, who appeared in videos from several of the homicide crime scenes in Stockton.
The San Joaquin County Office of the Medical Examiner identified the Stockton victims on Monday as Paul Yaw, 35, who was killed on July 8; Salvador Debudey Jr., 43, who died on Aug. 11; Jonathan Hernandez Rodriguez, 21, who died on Aug. 30; Juan Cruz, 52, who was killed on Sept. 21 and Lawrence Lopez Sr., 54.
Lopez was shot shortly before 2 a.m. on Sept. 27 in a residential area just north of downtown.
Police said four of the Stockton homicide victims were walking alone and a fifth was in a parked car when they were killed in the evening or early morning in the city of 320,000 residents, located about 50 miles south of the state capital, Sacramento.
