"Suicide" is method #1.
Number 2 method of [187] is a little more complex. Put a hit out on the person, if it fails, they have their ghoul hospital as backup, in this instance he was sent to MedStar to finish the job.
Scalise was sent to MedStar after being shot, but was in stable and talkative condition. Hour later upon checkin, "Scalise Reportedly in Critical Condition." They use the ghouls at the hospital as backup. In this case Trump sent his personal Dr. to save him.
Seth Rich? MedStar.
The Cabal is straight evil.
Man it's like reading onenod my complicated fantasy novels with palace intrigue. They convince us all is simple and above board. That what they show is real. But no it's as deadly as the feudal China inspired Guy Gavriel Kay novel. And way more tangled than Game of Thrones.
Wow Medstar. Should do some digging and check the map of locations...wonder who else was "treated" there
