A 32-year-old inmate was found dead at the Bexar County Jail.
Antonio Obregon, 32, was found bleeding and unresponsive on the sixth floor of the jail Saturday night, said Bexar County Sheriff's Office spokesman Paul Berry.
Obregon was taken to San Antonio Military Medical Center, where he was pronounced dead.
Berry said it doesn't appear other inmates were involved in Obregon's death, which doesn't not appear to be a suicide.
Obregon has been jailed in October on aggravated robbery charges.
