im betting its a ruger mark ii with integral silencer and subsonic ammunition. smart choice. he didnt collect his brass though (the spent shell casings) unless he palmed them as     suggests. idk.  he seemed very calm. idk if hes a pro though. hard to tell. hes no nigger tier stick up man though. hes put some thought into this. the backpack with spare clothes, using a bicycle as a getaway vehicle. hes all masked up, calmly shoots him first once in the leg to immobilize him. im doubtful its the first time hes ever killed someone, ill say that much. hes very calm, thats not a "normal" person.  nypds finest are on it im sure, and theyve got some very good detectives. its tough in murder cases though if the victim is not well known to the assailent. and the ceo of a health insurance ... well fuck his enemies include half the republic. the next 24 hours are critical. he could easily already be on a flight out of the country.
