Baltimore broke its annual per capita homicide record after reaching 342 killings Friday. With just over 600,000 residents, the city hit a historically high homicide rate of about 57 per 100,000 people after recent relentless gunfire saw eight people shot — three fatally — in one day and nine others — one fatally — another day. The total is up from 309 in 2018 and matches the 342 killings tallied in 2017 and 2015, the year when the city’s homicide rate suddenly spiked.
