SPOKANE, Wash. -

Spokane Police Chief Frank Straub said Monday morning, following the arrest of the suspect in the beating death of WWII veteran Delbert Belton, that robbery, not race, was the primary factor in the attack last week.

Straub made his comments six hours after the Spokane Police Patrol Anti-Crime Team arrested Kenan Adams-Kinard, 16, at an apartment in the 500 block of W. Montgomery. Adams-Kinard was taken into custody without incident and booked on charges of first-degree murder and first-degree robbery.

The other suspect in Delbert Belton's killing, Demetrius Glenn, 16, was arrested last week.

"Today I would like to assure our community that the two individuals we believe were responsible for the robbery and murder of Mr. Belton have been taken into custody," Straub said.

Throughout the weekend, Spokane Major Crimes detectives received numerous tips and worked with the faith-based community and the Adams-Kinard family to encourage Kenan Adams-Kinard to turn himself in. Early Monday morning, PACT members received information on Adams-Kinard's whereabouts and responded to an apartment in the 500 block of W. Montgomery, where he was arrested.

Three other people, all juveniles, were arrested for rendering criminal assistance to evade police apprehension, a Class B Felony, for helping hide Adams-Kinard from police.

"I would like to make it very clear: The motive for this attack was robbery. Race was not a factor. Additionally there was no gang activity that was associated with this incident," Straub said.

Belton's wallet was found in the vicinity of the crime scene. It's not known how much money was taken or whether there were any credit cards taken from his wallet that the suspects attempted to use.

Straub added that Delbert Belton, or Shorty, as his friends called him, didn't go quietly, but instead fought back against the suspects who attacked him.

"It was a robbery that, two young people -- committed on a victim. A ready victim. Our information is that the individual fought back and that may have made this a worse situation, and I'm not being critical of Mr. Belton, I would certainly encourage individuals to fight back and he should have, but it shouldn't have happened to begin with," Straub said.
