Nearly half of U.S. murder cases go unsolved, trailing behind other countries due to resource issues and high gun prevalence.

Nearly half of murder cases in the U.S. remain unsolved, with a national clearance rate of 58% in 2023, far lower than countries like Australia, Britain, and Germany which have rates between 70% to 90%. Factors contributing to the low rate include resource shortages, high case volumes, gun prevalence, gang crimes, and community distrust of police. Experts recommend increasing investigative resources and using new technologies to boost clearance rates.
