A man stabbed to death became the 300th homicide victim of 2015 on Saturday, the first time the city has reached that gruesome milestone since 1999. As of Tuesday evening, five more men had been shot dead, pushing the city's per capita homicide rate — based on the recent population estimate of 622,793 residents — to 48.97 per 100,000 residents. That breaks the record of 48.77 homicides per 100,000 residents set in 1993, when there were an estimated 723,802 city residents and the city hit its highest number of killings ever, with 353.
