One of those wounds was a contact wound though, and the other would have had to have been very close to SS’ head just based on the shooter almost certainly being in the backseat. That wouldn’t have taken any special talent.
Not that we know much for sure, but I keep attributing the two shots, the single cartridge found and the odd presence of the car seat in the passenger area with SS to a different scenario. It seems there was an intent that the deal meet start in RP's driveway (the map search on SS's phone...) and a mere 4-minutes after their arrival the Kia is headed toward the apartment building where it was abandoned. MG was dragged into the back seat and there would have been evidence of that on the ground or surface at whatever location it happened: Blood, skin, fabric and similar. There is no mention of the car moving between 11:50 and 11:54. A couple of
predictions:
There will be such evidence found on the driveway or possibly the street at Charley Chan.
There will be another cartridge found. And only one. Near the same locale.
CP will be found to be himself a small time drug dealer.
It will be found that CP is a customer of substantial duration with MG. And he had placed a prior order within the past month or possibly 5-weeks.
The volume of the prior order, and of the one the night of 12/21 were both small...nothing more than $300 involved.
It will be found that CP also has connections with some group that had cause to want MG dead.
There will be GSR found on the interior of the KIA on the passenger side. Some will be under the child seat.
The weapon will not be found unless CP or RP indicate where to find it. It will be a small caliber weapon and may have had a suppressor.
MG's blood will be found in quantity both on the driver's seat side and in the back seat. A more minor amount will
be found on the rear quarter panel and on the door sill of both drivers side doors.
I believe: CP made contact to arrange a delivery and was expecting RP alone. He then hid outdoors awaiting the KIA. The car drives up, stops and he immediately approaches from the passenger side. May have had to tap on the passenger window....He reaches across the car and fires on MG: thats the casing in the car; most semi's eject up and to the right. He has already wrapped his left hand around SS's mouth; she looks toward MP and he shoots her almost immediately. He finds he can't get MP in the back seat with the baby carrier in place so he moves it to the spot where it was found and pulls MG out of the front seat and into the back.
As to why SS was even there? I got nothing unless she had previously been a classmate???
All MOO and strictly conjecture....much of it could be wrong.
