He's also possibly linked to the killing of another MRA lawyer (Marc Angelucci) on the opposite side of the country a week prior using the same MO. Walked up to door dressed as delivery man, asked if the person who answered was Marc, then asked for Marc because he had to sign for the package. When Marc came to the door, he confirmed that was Marc and shot him. Died on the scene.They ID'd the shooter. Guy was an MRA lawyer who acted like a caricature of an MRA lawyer.
The witness of the Angelucci shooting described the man as thin, white and with salt and pepper hair. If he was wearing a hat as part of the disguise, that could fit Hollander (wouldn't see his bald spot, but would see the hair around the base of the hat).
Before the talk of Hollander being linked to Angelucci's death there was speculation of if it had to do with a case he was nearing the end of and likely to win that involved a 400 acre ranch being taken by the state as a consequence of a false rape allegation against it's owner.
