Marysville police arrested Samuel Hartbower after a Save Mart employee was killed.

Sunday's arrest is the accusation. CBS Sacramento reported the booking as suspicion of homicide and assault with a deadly weapon. KCRA described the same booking as charges of those offenses. A suspicion booking is not a conviction. Investigators told CBS Sacramento they do not believe Hartbower and the employee knew each other.

CBS Sacramento reported that officers responded a little after 2 p.m. Sunday, Oct. 11, 2026, to the Save Mart on J Street in Marysville and found a man being detained by people outside. Police said a weapon was recovered nearby. Inside, officers found an employee who had been stabbed at least once. Bystanders and officers started first aid, CBS Sacramento reported, but he died at the scene. A second man, seriously injured, took himself to a hospital before officers arrived. CBS Sacramento reported his injuries were not considered life-threatening. ABC10 reported the call at about 2:15 p.m. at 828 J Street. The Sacramento Bee reported bystanders subdued Hartbower outside the Save Mart in the 800 block of J Street before officers arrived about 2:15 p.m.

CBS Sacramento reported police arrested 33-year-old Samuel Hartbower on suspicion of homicide and assault with a deadly weapon. KCRA and ABC10 reported he was booked into the Yuba County Jail. KCRA described that booking as charges of homicide and assault with a deadly weapon. The Sacramento Bee reported it as suspicion of those offenses. The stations are describing the same Sunday arrest. An arrest, whether the copy says suspicion or charges, is the accusation police made at booking. It is not a verdict.

CBS Sacramento, KCRA, and ABC10 reported Hartbower had an active felony assault warrant from the Yuba City Police Department and was on post-release community supervision in Yuba County. The Sacramento Bee reported the warrant was an outstanding felony arrest warrant on an assault charge out of Yuba City, in neighboring Sutter County. That warrant is an older case. It is a separate accusation from Sunday's stabbing.

CBS Sacramento reported investigators do not believe Hartbower and the employee knew each other before the stabbing. Police described the attack as an isolated incident and said there is no outstanding threat to the community, CBS Sacramento reported. KCRA reported that, based on the preliminary investigation, police believe the suspect and the victims did not know one another, and that the incident appears isolated. The Sacramento Bee reported police said Hartbower did not know either victim. Marysville police confirmed Monday that the man who died worked at the store, CBS Sacramento reported, and that his identity has not yet been released. KCRA reported the victim's name is being withheld pending next-of-kin notification.

Save Mart released a statement Monday, CBS Sacramento reported. "We are heartbroken by the senseless act of violence that took the life of our Save Mart Team Member at our Marysville store on Sunday afternoon," the company said. CBS Sacramento reported the statement also expressed condolences to the employee's family and coworkers. The company statement names a loss. It does not identify the employee, and it does not decide the case. All defendants are presumed innocent until proven guilty in a court of law.
