He does try and cancel the deal but these guys are pissed. They weren't gonna do this job for free and they need the money. You see people who do this kind of stuff aren't really normal they don't keep regular jobs, they live on the fringes of society even sometimes. Almost all of them are alcholics, drug addicts and LOSERS.
Lolly ,Lolly Ice HEADS.
They actually know too much about Darin and Darlie. If Darin was stupid enough to hire them he wouldn't have been smart enough to protect his family from them.
If they are independants and they cased him they might have scammed their way in sometime past.
If hired Darin might have let them in and they had seen his house.
They think Darlie is SEXY, but a dumb , stupid deluxe. They decide to teach Darin a lesson 'bout doing biznes. He is a rich **** they know it they have seen his crib.
They scout it out late so the family will be asleep they intend to rob him for real anyway. Screw him and his insurance scam. Who does he think he is anyway.They are high. They are not extremely intelligent people.
They brought one knife with them.
They think the family would be upstairs asleep and they could scout it out quietly maybe score a little bling bling downstairs. It just might scare Darin enough to know they aren't punks to be ****ed with. They need this JOB.
Upon entering the den they trip over the sleeping boy Devon. The surprise for these crack heads was too much. The one perp starts the crime. He has to stab the boy and he does so with force and quiet delibertion. This killer has a clear knowledge of anatomy as evidenced by his placements of wounds. He is most likely a prior offender. IMO
When the one perp who didn't trip over a kid sees Darlie, on the couch asleep he may or may not have seen Damon also still asleep on the floor.He freaks too. He goes to the kitchen and gets a knife. He has to kill Darlie cause his partner just stabbed her kid to death. He goes back to the den. The one boy and Darlie are still asleep. One guy is standing behind Darlie and one of them wants to have a little fun. One of them grabs Darlie by the mouth from behind. This is not the best position to hold someone down on a couch folks. We are dealing with losers here not JAMES BOND.
Darlie does stuggle and manages to kick a glass top table over. This awakes Damon who is dispatched by the killler who had taken the knife from the kitchen. The perps don't want to fight her that hard for some *advertiser censored* so they proceed to the task at hand She is pinned and the killer doesn't feel confident enough to stab her in the heart right between his own legs. He is going to cut her throat to finish her off. He has a plan.
When he grabs her wrists to still contain her so he can reach her throat and get off her he releases some pressure on her arms, she fights anew. He stabs her arm as the only direction they could come is up and he has released his hold on her arms now. That works she quits fighting and he thinks he is home free. He is not a trained killer he doesn't know- it is not that easy to cut the throat of a person laying down. If his patner was holding her mouth shut he may have actually kept her head bent too far forward for a fatal cut to be made.
He cuts her deep he thinks in one quick slash to her neck. He steps back to makes sure he looks for blood and she is bleeding. His partner has deserted him after having to kill a kid, and all this ***** it is time to book. He has taken off.
He starts to leave and Darlie is roused, either by Damon or by the attack being over. She glimpes a figure at the end of the couch. It moves towards the garage. She hears a glass breaking. Even though she has been thru an attack and she really isn't sure of things. The intinct to stay alive and the post trauma makes her doubt she really saw someone. Am I dreaming, was this a nightmare? She gets up and her rollercoaster ride into hell begins when she realizes what happened to her children.
If hired, or targeted, with or without Darins cooperation, I really don't find it too hard to believe. I see two people commiting this crime.
