QUINCY - A suspect in a lengthy police chase Monday night in Grant County died at Quincy Valley Medical Center following his arrest.
Quincy police had attempted to stop a vehicle for a traffic violation just after 9 p.m.. The driver, identified as 29-year-old Quincy resident Marcos Avalos-Barrera, failed to stop and led officers on a chase around Quincy for more than an hour, according to Wenatchee police Capt. Edgar Reinfeld.
At about 10:15 p.m., Avalos-Barrera voluntarily stopped and was taken into custody after Grant County deputies, Moses Lake police and state troopers had joined the pursuit.
Shortly after being placed into custody, Avalos-Barrera told police he was not feeling well. He was taken to the Quincy hospital just before 10:30 p.m. Officers were granted a search warrant for the suspect’s blood as it was believed he was impaired. While at the hospital, Avalos-Barrera’s condition declined rapidly and he died despite life-saving efforts by medical staff, according to Reinfeld.
The in-custody death portion of the incident is being investigated by the North Central Washington Special Investigation Unit, a multi-jurisdictional team. The investigation unit was requested by Quincy police as all large agencies in Grant County were directly involved.
