SAN JOSE, Calif. – The Santa Clara County District Attorney’s office ruled on Wednesday that two officers who shot and killed a knife-wielding man in 2025 acted lawfully.
The officers shot and killed 48-year-old Mateusz Dzierbun 14 times after he charged them with a knife. The officers had responded to a call placed by Dzierbun, reporting that his nine-year-old son had been stabbed.
Dzierbun, in the 911 call, said his son was dead, and at first reported that another man had stabbed the child, then later admitted he had killed his child, telling dispatch, “They were going to torture him… I had to do it.”
