Steve Ebert, 59, superintendent of the Cordova Recreation and Park District, was fatally shot as he arrived for work at the district office in Hagan Community Park early Monday.
Dupree was arrested this morning on suspicion of murder after he flagged down a police officer in West Sacramento and said that police in Rancho Cordova were looking for him, according to Sacramento County sheriff's spokesman Deputy Jason Ramos.
Ramos said Barber had been laid off recently from his park district job and Ebert was "instrumental or at least played a role in" the layoff.
"We pretty much think it's directly attributable to that," Ramos said of the motive for the shooting.
Barber is a Rancho Codova resident.
A fellow district employee found Ebert's body shortly after 6 a.m. Monday when he saw a car idling inside the park with its lights on, Ramos said. The employee went to investigate and found Ebert's body slumped inside.
His weight on the car's brakes likely brought the car to a stop after the shooting, Ramos said.
