David Sloan, 34, of Mount Vernon, Illinois, was killed on July 4, 2018 following a day of heavy drinking and a physical altercation with his brother, Matthew Sloan. The brothers ended up at Matthew’s rural Mount Vernon home; David followed Matthew into his bedroom and Matthew shot him through the bedroom door.

Matthew Sloan was tried on first-degree murder charges. A Jefferson County jury found him guilty in July 2019 after just over two hours of deliberation. At trial Matthew said he believed he acted in self-defense, but the jury rejected that claim. The court sentenced Matthew, then 37 at trial, to 80 years in prison.

The case had a profound effect on both sides of the family: David’s wife, Sarah Sloan, lost her husband, and Matthew’s parents lost one son to death and another to prison. Did anyone in Mount Vernon have information about the events leading up to that July 4 confrontation?
