KENT, Wash. -

A judge has set bail at $2 million for a man arrested for investigation of homicide in the shooting deaths of two men at a Kent, Washington, gas station. One of those killed was the manager.

In court papers, police say 29-year-old Leland Dean Russell Jr. told them the argument he got into Wednesday at the gas station was about "disrespect."

Witnesses said two men in a black Cadillac with music blaring pulled into the Shell service station in a way that blocked other customers. Witnesses say the two argued with others and one of the men pulled out a gun and shot the two victims.

Kent police Cmdr. Jarod Kasner says detectives believe they have arrested the gunman. He says detectives have identified the second man in the car and are looking for him. Police have also seized the vehicle.

The King County medical examiner identified one victim as 52-year-old David Christianson. The Seattle Times says Ariff Gulamani, who owns the combination gas station and fast-food restaurant, says Christianson was the store manager. The second victim has not been identified.
