The driver of the vehicle rammed into a patrol car and left the scene, striking and killing Apple, according to Lisenbee. No other injuries were reported.
Lisenbee declined to say why the vehicle was being sought, citing the ongoing investigation.
Police later found the vehicle in Bella Vista, about 9 miles (14 kilometers) west of Pea Ridge, and arrested Shawna Cash, 22, of Pine Bluff, and Elijah Andazola, 18, of Bella Vista, on warrants including capital murder or attempted capital murder and fleeing.
Police did not say which suspect is believed to have been the driver, although preliminary charges against Cash include driving with a suspended or revoked license and reckless driving.
Both are jailed without bond and jail records do not list attorneys who could speak on their behalf.
Gov. Asa Hutchinson ordered flags in the state to fly at half-staff until Apple’s burial.
“My prayers are with Officer Apple’s family and the entire Pea Ridge community during this time,” Hutchinson said in a written statement.
