Maybe he was counting on the staff member stepping in the room far enough to see the carnage, and when he didn't, Joran had no reason to ask him to step in. Maybe he was going to say "my God, she was fine when I left her" (not knowing about the hallway camera yet). If he'd been thinking on his feet he could have said, "come in while I put this coffee down and I will give you a tip for troubling yourself to open my door." THEN the carnage would be visible. So the guy leaves instead.
Second issue- he reportedly did cocaine around the time he killed her or after wards. He went to the airport and saw cops and got so paranoid (as you will do if you are high on coke) he chickened out. Truth be told, the cops didn't know a thing about Stephany's death yet, they weren't looking for him! He could have hopped a plane to Aruba and been untouchable. Back in his mamas arms and bellying up to a casino table the very next night.
Gambling away what was left of Stephany's winnings.....
