Gun violence surged in Baltimore between June 19 and June 29 this year, with 14 homicides and 15 non-fatal shootings in that 10-day stretch.

The shootings come five years after the city health department created Safe Streets, a program aimed at preventing such violence by hiring ex-offenders to mediate conflicts in high crime neighborhoods, focusing on youth ages 15-24. According to the department, they have conducted more than 750 mediations at four sites since opening in 2007.
