Hundreds gathered for a candlelit vigil Friday night in honor of an 88-year-old veteran of World War II who police say was murdered in a random attack outside an Eagles Lodge in Spokane, Wash.

Police in Spokane have arrested one of two teens suspected of fatally beating Delbert Belton, who was found by police with serious head injuries and died in the hospital Thursday.

Police contend that two 16-year-old boys approached Delbert Belton in his car at random Wednesday night. The other suspect remained at large early Saturday.

The crowd at Friday's vigil outside the the Eagles Lodge joined in a chorus of "Amazing Grace" as some attendees lifted American flags into the night sky, The Spokesman-Review reported.

Belton's death has struck a chord nationally and sparked outrage on social media.

"He fought for this country," said Belton's sister, Alberta Tosh, on Friday. "Then he comes home and a couple of creeps kill him in the worst way."

Police Chief Frank Straub said there was no information that the attack was motivated by anything other than robbery. Police were offering no details about the crime itself, including what was taken, if anything.

"I don't really care what their motive was," Straub added. "We are not going to tolerate this." Such random attacks are rare in Spokane, a city of 210,000 people in eastern Washington, Straub said.

Police say the arrested teen was being held on charges of robbery and first degree murder.

Straub identified the suspect still at large as 16-year-old Kenan D. Adams-Kinard. Even though he is a juvenile, his name and photo were released because he remains a danger to the community, Straub said. The Associated Press doesn't usually name juvenile suspects, but is identifying the teen because of the manhunt.

"We are asking the community's assistance to locate him," Straub said. "We are asking Mr. Kinard to surrender immediately."

"He displayed very aggressive and violent conduct with his assault of Mr. Belton," Straub said, adding that he believed the arrest of the second suspect was imminent.

Both of the suspects have juvenile court records and have past convictions for assault, Straub said.

Straub also offered his condolences to Belton's family.

"He is a World War II veteran who suffered injuries in Okinawa," Straub said. "The Spokane Police Department has been working tirelessly to identify and apprehend the suspects."

Belton was born and raised in Spokane and joined the Army during World War II. His sister said he was shot in the leg on Okinawa, site of one of the fiercest battles of the war in 1945.

"He was shell-shocked real bad," Tosh, 78, said. "But it got better."

After the war, he spent 33 years working for Kaiser Aluminum, before retiring in 1982.

"He was a tough old bird, I'll tell you that," Ted Denison, Belton's friend for 23 years told the Spokesman-Review.

The station says he went on to work for Kaiser Aluminum for 30 years. Friends say he was known as “Shorty,” and enjoyed playing pool and working on cars. His wife passed away several years ago.

"He was just such a nice person for God's sake. I don't think Shorty had a mean bone in his body," friend Betty told KXLY-TV.com.

"He didn't deserve this. It's so senseless and unnecessary," she said.

In retirement, Belton loved to dance, play pool and repair old cars, family members said.

"He was very active and everybody liked him," said niece Pam Hansen. "He'd never think about harming another person."

Belton was called Shorty by his friends because he was little more than 5 feet tall, Hansen said.

She believes he was targeted by the assailants because of his age and size.

"He was defenseless," Hansen said.
