Dennis Robert Hall was an 80-year-old Beaverton, Oregon resident who was shot on the morning of Friday, April 6, 2018. A 911 call from his home on Southwest Hoodview Place at about 5:19 a.m. reported that his son, 47-year-old Gregory Dennis Hall, had shot him. Dennis was found with multiple gunshot wounds, taken to a local hospital, and later died of those injuries.

Gregory was arrested at the scene and charged with murder. He told investigators the shooting followed an argument, and court proceedings revealed he suffered from a chronic mental illness. In July 2020 a judge found Gregory guilty except for insanity on one count of murder with a firearm and ordered him committed to the Oregon State Hospital under the Psychiatric Security Review Board.

If anyone knew Dennis, his routine, or the relationship between him and his son, please share information that might help clarify events leading up to that April morning.
