Events of Criminal Case
Walter became a suspect after he was seen at the crime scene, after he identified the victim as one Will Wyoming. He explained the victim was born and grew up in Devil's Ridge, but he had been away for some time. A few days ago Will returned, Walter remembered he stopped by the post office for some stamps and whatnot. As for why Devil's Ridge was abandoned, Walter said it happened weeks ago; he was delivering mail around Coyote Gorge, but when he returned to Devil's Ridge the whole town was empty. Considering the victim was recently there, Isaac and the player decided to look around the post office for more evidence.
Walter was spoken to again regarding an envelope full of cash the victim had his hands on. He explained that the victim had been going through other people's mail, like the one Isaac and the player found, he caught Will in the act doing so. It made him mad that he was going through other people's mail like that when they are not there to protect themselves, so he felt it was no surprised Will ended up getting himself killed.
Walter was found to be innocent after the team incarcerated Lucy Liang for Will's murder. But Maddie and the player needed a word with him in regards to deciphering an atlas to help Ennis Sparhawk and his group get to El Gordado. Walter was already having trouble as he got word his post office was being closed down, but when he heard about the situation he said he would be happy to. However, he lost his compass on the main street and he could not leave without it. They decided to search the main street and after finding it they went to see Ennis and informed him that Walter would come along and lead them to El Gordado.
- It is heavily implied but not confirmed during the events of Like a Pig to the Slaughter that Wilbur Abernathy, a post office worker in modern day Grimsborough, is Walter's descendant.
