Weird that they sent a robot in with a bomb to blow up the suspect
Sounds odd to me too. I wonder if the guy had a vest on like the European terror attackers did and he set it off, and they just don’t want to say that yet because it’ll have a lot of implications and/or they may hope to keep other perps unaware of how much they know... so, they needed an explanation for the coroner to write down until others involved, if any, are caught.
