Authorities say the girlfriend of a man charged in the fatal shooting of a Texas sheriff's deputy during a traffic stop has also been charged in the officer's death. An arrest affidavit alleges that 20-year-old Arlene Pina can be heard on police video saying "beat that expletive" in Spanish after her boyfriend, Facundo Chavez, started striking El Paso County Sheriff's Deputy Peter Herrera following the gunshots. Pina was charged with capital murder on Saturday and is jailed on $1 million bond. Online jail records don't list an attorney for her. Chavez was charged with capital murder after being accused of firing 15 shots at Herrera in March after the deputy asked Chavez to exit a car in San Elizario, about 25 miles (40 kilometers) southeast of El Paso. Herrera died two days later.
