Murders are down nationwide. Researchers point to a key reason

City officials in Detroit say the city is experiencing the lowest number of homicides since 1965. Police Chief Todd Bettison says the decrease is due to a citywide team effort.

Homicides are falling dramatically in many U.S. cities, after a surge in 2020 and 2021. Analysts say a reinvestment in communities from local government after the pandemic's disruption is a key reason.
