 During the searches and investigations, all the boats in the lake were checked, but one is said to have been forgotten by its owner due to its bad state.That Alvar could not swim suggests he would not have entered a boat, but if he had, his lack of ability to swim could have become fatal.It is said that the fact that Alvar's clogs have not surfaced at the waterside, as opposed to many other clogs, suggests that he did not drown in the lake.
