Just saw an interview on the local news. A neighbor said the mother wore traditional Muslim clothing and the parents moved back to their home country about a year ago. And he also said the older brother went from looking like a traditional westerner to wearing Muslim garb and a beard. About a month ago he shaved the beard and started wearing traditional western clothing.
With that info, there is no doubt he was a selff-confessed Jihadist Muhajideen who performed this act of terror as a religious sacrifice against the kafir population of the world.

Why do suicide bombers shave their bodies?
By Juliet Lapidos|Updated Tuesday, March 25, 2008, at 6:31 PM
U.S. Forces raided a suicide-bombing network in Iraq over the weekend, killing 12 men in the process. Six of the dead had shaved off their body hair, which military officials said is “consistent with final preparation for suicide operations.” Why would a terrorist shave before blowing himself up?
So he’s clean when he enters heaven. Traditionally, Muslims purify corpses by washing the skin and nails and sometimes by shaving the pubic hair. But suicide attackers are deprived of a proper burial, since there are usually no remains. To compensate, the attackers shear themselves ahead of time, both to guarantee some level of cleanliness at the time of instant incineration and to prove extreme devotion to personal purity.
So recent programming and training.
