She lost two sons to gun violence; five years later, still no arrests
Barely half of murder cases in the U.S. get solved. The national homicide clearance rate is at an all-time low, according to FBI data. In the mid-1960s, more than 90% of murders were solved, generally resulting in the arrests. By 1990, that percentage fell into the 60s. Then, by 2020, as homicides surged, the national clearance rate dropped to about 50% for the first time ever.
