In the second video, the driver appears to have a bit of a "gut."
"A co-worker saw him head to his truck in the parking lot about 7:05 p.m." Did anyone see Bo actually get into his truck, or is there surveillance footage showing him doing so? This happened on a Saturday, when only urgent care services are offered, at the very end of the day. I suspect there would have been fewer people present than on a weekday.
What if the perps were initially interested in stealing prescription drugs? They could have had a third person (I do think there is a third individual involved, for getaway purposes) drop them off on hospital premises shortly before 7 PM, found Bo's truck to be unlocked, hid in the back, and when Bo got inside, surprised him with a gun. At that point, they demand Bo let them inside the hospital and access to meds. However, Bo was an X-ray tech, so I seriously doubt that he had access to anything these individuals would have been interested in; the perps become frustrated, just grab a box of samples (at my former FIL's clinic, they have samples from drugs reps laying around in the staff break room ... :facepalm
, get back into the truck with Bo, get his bank PIN and then ...
. Or, the box could be completely irrelevant to the case (Bo could have already had it sitting in his truck, to be found by one of the perps while the latter rifled through the interior of the vehicle).
