EL PASO, Texas - The second person arrested in the murder of El Paso County Sheriff's Deputy Peter Herrera pleaded "not guilty" on Wednesday afternoon.
20-year-old Arlene Piña entered the plea during an arraignment hearing at the El Paso County Courthouse. She's charged with capital murder of a police officer.
According to investigators, Piña was the passenger in a car when 27-year-old Facundo Chavez shot Deputy Herrera after he was pulled over in San Elizario back in March.
Piña and Chavez were arrested the same morning however, Piña was released because officials said there was not enough evidence. After investigators were able to review the video footage from the patrol vehicle and body camera, they said they were able to gather enough evidence to arrest her again.
