Old man Skyler was a solitary but friendly old man who lived in Lander, Wyoming. As a hobbyist, he loved nothing more than making model planes and selling them cheaply to kids at local events. He wasn't a rich man, but lived humbly and generously. Unfortunately, old man Skyler passed away this March from a heart attack.
The people of the community were sad, but as they began to organise his affairs it was discovered that he had arranged for his life insurance to form a trust to help the area. However, the insurance company claims that his insurance has run out, and that they cannot confirm that he died while the policy was still active.
Old man Skyler was last seen alive on Thursday the 5th of March, by the postman who was delivering a package. He'd talked to the postman about the package, which was a new model plane that he was very excited about. He was discovered dead on Friday the 13th. Everything was covered in flock, which he must have knocked over in his last moments. His insurance policy was valid up to and including Monday the 9th.
As an expert puzzler, the Lander community brought you in to help sort things out. His house has been sealed and preserved since the old man was found dead. You go inside and have a brief look around the place, and then settle at the desk, stirring up flock as you sit down. On the desk is the new model plane:
Can you prove (as much as possible), one way or the other, whether or not old man Skyler died before his insurance ran out?
There's more to the image than just the glue label, but nothing you won't have the tools to find.
