My understanding is that the husband was shot at the door, either falling back into the apartment or just outside of it.

According to the search warrants, a woman flagged down police and directed them to Barakat's and Yusor Abu-Salha's condo, saying her friend was bleeding. When officers arrived, they found Barakat dead in the front doorway bleeding from the head; one of the sisters was found in the kitchen, and the other was in the doorway to the kitchen.

Re: parking
My understanding is that each condo got one parking spot. The rest were for visitors,
the alleged killer warned the neighbours not to park in the visitor's space next to his assigned parking because it was for his wife. The victim's sister said they steered clear of that spot after some drama, but I'm not aware if anyone was parked there at the time of the murders, or if this even fuelled he killing at all. She claims neither her brother or his wife's sister were parked there.
