A California brother and sister who are accused of killing a man for his SUV were also planning a murder spree to improve their financial situation, detectives alleged in court. John Chong Moon, 55, and Cindy Kim, 59, of La Palma thought killing their sister and her family, along with a neighbor of their mother's, would elevate them to a life of luxury, prosecutors allege. Los Angeles County Sheriff's deputies were first alerted to the strange case on Feb. 25, 2025.
