SALT LAKE CITY — A Salt Lake physician who was also a husband and father of two daughters was killed over the weekend by a suspected impaired driver who ran a stop sign, according to police.

About 5:20 p.m. Friday, a 26-year-old man ran a stop sign at 1100 E. Bryan Avenue (1565 South) and collided with another vehicle.

Arthur Miller, 55, was killed.

“Honestly, one of the greatest human beings I know. Just a sweet, honest, generous, decent guy all around,” a man who identified himself as Miller’s neighbor told the Deseret News. “Just the greatest neighbor you could ever ask for. He’s a doctor — among other things. A real Renaissance guy.”

The driver of the vehicle that hit him was taken to a local hospital in critical condition. His injuries are not believed to be life-threatening. Police had not released the driver’s name as of Monday.

Salt Lake Police Sgt. Keith Horrocks said investigators were looking at whether the driver was under the influence of drugs and/or alcohol.

The crash was witnessed by a third driver who had also just been involved in a minor hit-and-run accident with the same 26-year-old man, according to police. That driver was following the man to try and get a license plate number when he witnessed the second crash, according to police.

According to his Facebook page, Miller graduated from Bountiful High School and the University of Utah School of Medicine.
