The victims were all killed in much the same way. There was a blue goo left behind in the wounds, which proved to be lethal when she subjected a lab mouse to it. Sadly, Cully's player can't really technobabble medical jargon, so the explanation to what's happening might soon be along the lines of "reversing the polarity of the ovid adrenal sphincter".
As the investigation progressed, the two FBI agents ended up in a jewellery store, and persuaded the shop owner to hand over three big diamonds ("only" worth $14M) for safe-keeping, in case the store would be burgled by invisible people with jaw-span of 1.5 metre that can chew through steel.
Oh, and the death count is currently at four. Might be five once an Arab Sheikh gets woken up by Agent Mulligan's phone call in the middle of the night, or when the killer realises that Agent Cully fits his/her/its M.O. to a tee. Help.
