The Texas Rangers are conducting a death investigation after a female inmate who was found unresponsive at the Cameron County jail Wednesday morning was later pronounced dead at a Brownsville hospital, according to the Cameron County Sheriff's Office. 

The woman, identified as Lidia Grover, was taken to Valley Regional Center in Brownsville after she was found unresponsive at the Carrizales-Rucker Detention Center.
