A Lancaster father and mother of four have been convicted of murdering their teenage son and daughter and abusing their two younger boys in 2020. “This was a monstrous act of cruelty that shattered an entire family,” Los Angeles County District Attorney Nathan J. Hochman said. “Two innocent children were brutally murdered, and their young brothers were left to live through unimaginable horror. The jury’s verdict delivers justice for these affected children and sends a powerful message: Those who commit such evil acts will be held fully accountable.”
