By CHAD GARLAND | STARS AND STRIPES Published: January 6, 2021 A 20-year-old Marine who was shot and killed while on leave in his Idaho hometown last week was a member of the service’s high profile silent drill platoon. Lance Cpl. Davis Mosqueda was with a group of friends at an apartment in Boise on Dec. 30 when Devon Arnold, the suspect in the fatal shooting, showed up just after 1 a.m., the Boise police said in a statement. Mosqueda left the apartment to check on a friend when he was shot near the parking lot, the police said. The young Marine was taken to a hospital with multiple gunshot wounds, Ada County coroner Dotti Owens said in a statement last Thursday, but efforts to save him failed and he was pronounced dead in the emergency department.
