yeah, you know, despite that horrible week, bike fatalities are fairly rare in Pittsburgh, fortunately.
In my memory, and this is within the city limits only:
2004: on Second Ave, Hazelwood (adult)
2009: Sennot St, Oakland (adult)
2010: Bausman, Knoxville (6-year old)
2012: 2 adults, Penn Ave Point Breeze
while Pittsburgh isn't in the report (we're not one of the largest 50 cities, which is a crock of shit if you ask me), here's a comparison:
In Fresno, nearly 10% of ALL traffic fatalities are cyclists, yet are only 0.7% of commuters. if Pittsburgh was in this report, we'd put .3 bicycle fatalities per year (as this was a 3-year average from 2007-9)
