THE CRIME SCENE
Why was the ejected shell of the shotgun found to the left and not the right of the body? This one is extremely important. More important than the heroin in my opinion. Why were standard tests not performed such as a GSR kit, analysis of the contents of the root beer can, (read the reports the can was found with liquid in it but logged into evidence as empty) fingerprinting of the greenhouse, etc.
Were any trajectory tests done to show what the position of the shotgun was when it was fired? If not why weren't they done?
Were any measurements taken to see if it was even possible for him to shoot the gun? If not why weren't the done? The picture of him with the toy gun is just that a toy gun this shot gun was much longer and Kurt wasn't a big guy.
Why did Sgt. Cameron lie to Tom Grant about Kurt being barricaded in the greenhouse and that the little 'stool was wedged up against the door'?
Why were items logged into evidence in the case turned back over to Courtney before the case was even 30 days old?
STRANGE BEHAVIOUR
Why did Courtney pretend to be Kurt's mother when calling in the missing person's report to the SPD on April 4th?
Why didn't Courtney tell Grant and the SPD that Kurt had been seen at their home on April 2nd?
Why was Grant told to watch a drug dealers house and check hotels for Kurt, but not told that Dewitt had seen him at the house?
Why did Dylan not show Grant the greenhouse when Rosemary Carroll is recorded as telling Grant that she heard Courtney tell Dylan to look in the Greenhouse.
Why did Rosemary Carroll think Kurt's death was suspicious? Why did she tell Grant about the divorce and the will? Why is she now silent?
Why did Courtney release that cropped image of Kurt with the toy gun, shortly after his death?
Why didn't Eldon Hoke (El Duce) come forward sooner?
"Frances and Courtney, I'll be at your altar." - Why doesn't anyone ever question this part of the note?
Why did it take 2 years for Sgt. Cameron to say that a rookie must have made a mistake in the police reports about "the marks on Kurt's hands" ?
Why hasn't Courtney sued Tom Grant for his claims, but yet sues everyone else on a spin of a dime?
Where was Pat Smear during the week of April 1st - April 8th?
Why didn't Nikolas Hartshorne the coroner, disclaim and deny the 1.52 mgs of heroin that was found in Kurt's body at the time of death after he has done numerous interviews (VH1 Confidential)?
Why did Rosemary Carroll, Kurt and Courtney's entertainment attorney, tell Tom Grant that "Kurt was not suicidal"?
Why did Rosemary Carroll tell Tom Grant that the note left by Michael "Cali" DeWitt sounded phony?
Why did Rosemary Carroll tell Tom Grant that Courtney had "no business in Los Angeles"?
If all of Kurt and Courtney's friends knew that he was suicidal, why didn't they keep an eye on him?
If Dylan Carlson knew Kurt was suicidal, why did he buy the gun for Kurt?
When Courtney found out that Kurt fled rehab, why did she contact a PRIVATE INVESTIGATOR and not the POLICE first?
Why didn't Courtney go back to Seattle to help locate and maybe save her "suicidal husband"?
Why didn't Courtney call all their friends and family up in Seattle and organize a massive search party the minute Kurt fled the rehab and headed back to Seattle?
Why did Rosemary Carroll back off Grant after he replied to the letter he received from her firm threatening to sue him? Did he strike a chord or something?
Why did Courtney want to keep Grant on the pay roll and get him to sign a confidentiality agreement if he had openly admitted to her what his feelings of Kurt's "suicide" were?
What happened to Cali, and why was he always around - in Rome, at the house, whenever there was a problem? Why wasn't he ever really interviewed/questioned?

Who else did the confidentiality agreement effect besides Rosemary Carroll? i.e. other friends/associates of Kurt and Courtney who can not speak about this, even if they wanted to?
GRANT QUESTIONS
If Kurt was in fear for his life, as Grant claims, why would he go home after fleeing rehab? Wouldn't he hide somewhere less obvious?
Seeing as Tom Grant is a private investigator. Why didn't he search the entire place, instead of just sitting in the car waiting for Dylan the first time, and only looking inside the house the second time, which was just a short time after the first time early Thursday morning of April 7th? You'd think him being hired to specifically search for a suicidal person, he'd have a look around everywhere on the property, not just the house, especially when the greenhouse isn't that inconspicuous. Anyone could see the window right above the garage. He used the excuse "it was dark and raining", why didn't he go back there at first light to have a thorough look at the entire property?
Why don't any of Kurt's close friends publicly support Tom Grant or the murder theory?
If Tom Grant has some more information on the murder theory then why won't he release it to the public? He says he's saving it for when the case gets reopened and goes to court, but it's been eight years.
