The commissioners selected Bexar County Deputy Leticia Vasquez from 29 applicants.
The vacancy was created when Barrientes Vela triggered Texas' resign-to-run law by telling local media she's running for sheriff. The law requires elected officials to give up their position if they declare a run for another office.
Barrientes Vela's statement about seeking higher office came as the FBI and Texas Rangers carried out a 10-hour raid of her Northwest San Antonio offices. The embattled constable also faces allegations that she used taxpayer money to pay for out-of-town training seminars she never showed up for.
Barrientes Vela is expected to remain on the job at least until an October 11, at which time a court is set to hear whether she's able to retain her position. Barrientes Vela's attorney argues that her comment to the media was not a formal announcement of her candidacy.
