Holy Moly...he used Mother of Satan..
He may have been a loner who fed off the stories of suicide bombers in his troubled mind...He may have been curious and gone to visit the Mosque where his roommate worshipped..
He may have decided to do this act purely out of deranged suicidal thinking..alone..but then perhaps not.
He may have only intended to kill himself..
Perhaps this unstable explosive went off early before his plan to take others with him could be realized.
many questions ..
I wonder how many suicides have been performed by using explosives in a public place...that were not meant to harm others and had nothing to do with terrorism..
I wonder.
