The probe into the jail cell death of Sandra Bland will be treated as thoroughly "as it would be in a murder investigation," a Texas district attorney said Monday. "There are many questions being raised about this case," Waller County District Attorney Elton Mathis said during an evening news conference. "It needs a thorough and exhaustive review."

Yet, Waller County Sheriff's Office Captain of Patrol Brian Cantrell said at the same press conference that Bland's July 12 death inside a Waller County Jail was already ruled a suicide.
