Next steps:
1) Secure bad guys.
2) Bomb squad checks for trip wires, etc. in the suicide vest.
3) Bomb squad removes the suicide vest from the victim and takes it to a secure facility for examination and detonation.
4) The shop keeper and customer start PTSD counselling.
5) As the bad guys regain consciousness, read them their Miranda rights.
Of course it should not take that long before everybody realizes this was just intended to be a distraction from the main (unsuccessful) attack at the school.
