I the most recent published article. PhiKapMom has some local info.
Probably should look in the stats for this before guessing, but my guess is that suicide involving a bomb is on the order of 10,000 to one against. My guess is most suicides are carbon monoxide, gun shot, sharp instrument, jumping off high place, or drugs. I'm not a young person, but this would be the first ever that I have heard of a suicide using a bomb that was not terrorist related.
