SPOKANE, Wash. -

"Turn yourself in." That's the message Spokane Police Chief Frank Straub had for Kenan Adams-Kinard Friday, the second of two suspects in the beating death of WWII veteran Delbert Belton, was died Thursday morning.

The first suspect, 16-year-old suspect Demetrius Glenn, turned himself into police just before midnight. Now the focus of the Spokane Police Department is on finding Adams-Kinard, and Straub said its only a matter of time before he's arrested.

Both suspects have juvenile records, including assault convictions. Now the two 16-year-olds will be charged as adults for the murder of Belton. They'll also be facing a robbery charge in connection with his killing.

In court documents released Friday, detectives describe the brutal scene they responded Wednesday night in the parking lot of the Fraternal Order of the Eagles in north Spokane.

Detectives found Belton bleeding profusely from his face and head, lying in the back of his car. Police believe two teens robbed Belton, beat him and ran away. Belton passed away several hours later at Sacred Heart Medical Center.

"We're not going to accept this behavior from 16 years olds or anyone else in this community," Straub said during a media briefing Friday.

The suspects were caught on surveillance video at stores near where Belton was attacked and left for dead.

Hours after those photos were released to the media and the public, Glenn turned himself in.

"It certainly demonstrates we as a community, and we as a nation need to be much more attentive to our young people. To have two juveniles made such a vicious attack to assault someone minding their own business suggests we have some temper issues we need to confront as a community and as a society," Straub said.
