i've watched enough murder interrogation videos on youtube to know that local police find murderers by tracking cell phone records at places where bodies were dumped. a ceo was assassinated so i'm sure the fbi will spare no resource or leave no stone unturned. they have him on video, with a time stamp of the time. so they can check all calls happening at this time in this vicinity. it's a densely packed place like ny but i'm sure they could round it down by many people by filtering women, non whites, and others that don't fit his stature. and they just zero in on probably a few dozen white guys and run a fine toothed comb through them and their internet history, whether they own guns, etc.
