Wagoner Police are investigating the city's first homicide in several years.
Detectives said 69-year-old Jimmy Arthur was shot twice in the head around 10 p.m. Thursday at a house he recently moved into, as his wife and nephew were in the home.
Lt. Benjamin Blair, the lead detective on this case, told News On 6 it's complicated since the only witnesses so far are the victim's wife and nephew, who are not ruled out as persons of interest.
"We don't a motive or a reason as to why what happened happened," said Blair.
Blair said the woman called 911 about her husband being shot while she was sleeping. Officers found Arthur dead on the floor of the front room of the home that used to be an art gallery.
"There was no physical signs of there being a fight or an altercation inside the residence," Blair said.
Blair said the victim's wife and nephew told officers they heard two gunshots.
Officers said they found shell casings and some guns at the home but not the one they believe was used in the crime.
Police do have a person of interest they're not naming yet.
"We believe it would have been more of a domestic incident or some of the stories that were given was that people had kicked in the front door, shots were fired from the front door and they fled the scene,” said Blair. “There's evidence to indicate any of that would have took place."
Blair said the victim and his wife recently moved into the house from Okay and that the nephew does not live at the home.
Police also said they went door-to-door to talk to neighbors, and no one had surveillance video or heard anything.
