Slate has a crime blog which is run by Justin Peters, Slate’s crime correspondent. Peters posts at least once a day, it looks like, and from what I can tell his writing is well informed and researched.
The second on is Homicide Watch DC. From their site: “Homicide Watch is a community-driven reporting project covering every murder in the District of Columbia. Using original reporting, court documents, social media, and the help of victims’ and suspects’ friends, family, neighbors and others, we cover every homicide from crime to conviction.” There should be something like this in every city.
This is a detail from an undated NYPD photo with the caption, “Lost children.”
