ROYAL OAK, Mich. – A 49-year-old man has been charged with murder in connection with the death of his girlfriend in their Royal Oak home earlier this week.
David Douglas Davis was arraigned Thursday morning on a first-degree murder charge and three gun charges.
He is being held in the Oakland County Jail without bond.
Theresa Diamos, 50, was found shot to death early Monday morning on Altadena.

"The suspect initially told neighbors and responding officers that there was an intruder, however, investigators found no evidence to support the suspect's initial claim," Royal Oak police said in a statement. "The suspect has not cooperated with the investigation."
Davis has convictions for assault, according to his criminal record with the Michigan Department of Corrections.
Royal Oak Police Chief Corrigan O'Donohue said Diamos' death is the first homicide investigation in the city this year.
Neighbors awake to sound of gunshot
Officers went to the home in the 800 block of Altadena Avenue just before 3 a.m. after neighbors awoke to the sound of a gunshot and called 911.
"At around three o'clock my dog started going crazy, which he don't do," said neighbor Bruce Simon. "So he come outside and he goes right over to the street and I got hit by flashlights from the Royal Oak police."
Neighbor Sarmad Awdish said he heard police giving an order.
"Just heard them say everybody get out of the house," he said.
Investigators spent hours at the scene collecting evidence and trying to figure out who shot and killed the woman.
Gary Andrus said the neighborhood is normally "pretty quiet."
"I walk my dog around here all the time, me and my wife enjoy walking through here," he said.
