The Pittsburgh metro area had about 100 homicides in 2006, a typical number in a city that consistently ranks among the safest in the United States, reports the city’s Post-Gazette. But what was different last year was a spike in unsolved cases outside the city. Allegheny County police cleared 20 cases and have a warrant in one other, but 17 were unsolved as of Friday.
In contrast, only six of the 29 homicides committed in 2005 remained unsolved by the year’s end. Police attribute the bump last year to an increase in drug-related robberies and a street culture of “no snitching,” in which witnesses balk at testifying.
