Oklahoma City police say a 25-year-old veteran was killed selling a gold chain outside a bank; an 18-year-old is jailed

OKLAHOMA CITY (Oct. 28) — A 25-year-old man who had just finished serving in the U.S. military was shot and killed Monday afternoon outside a bank in northwest Oklahoma City, where police say he had gone to sell a gold chain.

Officers were called to the First Citizens Bank near North Pennsylvania Avenue and Northwest 122nd Street just after 3 p.m., Fox 25 reported. They found Andres Navarrette Guerrero inside the bank with multiple gunshot wounds. He was pronounced dead at the scene.

Police first got reports of a bank robbery, but Master Sgt. Gary Knight said the shooting "did not have anything to do with the bank," KOCO 5 reported. Investigators say it was one person robbing another.

According to a probable cause affidavit cited by News 9 and KOCO 5, Guerrero had agreed to meet the buyer at the bank to sell a $2,000 gold chain. Police say the suspect, 18-year-old Keyalynn Gray, first went inside the bank so Guerrero would think he had money, then pulled a small AK-style rifle from a backpack. Gray told police he fired when he saw that Guerrero was also armed, the reports said. Guerrero shot Gray in the hand, police said, then stumbled into the bank, where he collapsed.

A witness parked nearby told News 9 that a security camera on his company's building caught a red car driving away, and that an officer later thanked him for video that was key to finding the suspect. Police found Gray at a home in southeast Oklahoma City. His car was abandoned a few blocks away, and investigators found clothing in a creek, News 9 reported.

Gray was treated at a hospital and booked into the Oklahoma County Detention Center on complaints of first-degree murder and first-degree robbery. Formal charges had not been announced as of Tuesday, KOCO 5 reported.
