It could have been a multi-person murder. Each would have their own motive (The diamond necklace) but not many family members would go as far as murdering their own, so I would personally take Edgar out of the equation. Vince was the one with the crowbar, and he called the police, as not to sound suspicious when he reported the murder. Vince claimed Edgar was on the floor, awake.

Vince would seem like the guilty one to me. He's only an elevator repairman, which isnt that great of a job. He could have sold the necklace to get lots of money and get a better job. He could have hit Chase with the crowbar while he killed Alice, explaining his blunt item injury.

Since Brain/Brian has no relation to Alice at all, he might not know who Edgar is. However, this wouldnt explain why he said Edgar needed money from her. Brian's punch injuries could have been from a mistaken Chase, or somebody else.

I can say one thing: It wasnt Edgar. Theres too much evidence pointing against him. I believe it's Vince because he seems to be the savior of this murder and he was the one who had access to the crowbar, the only object with a blunt side mentioned.

Please tell me I'm at least on the right track. I put lots of thinking into this.
