Dash cam video was released Tuesday of the arrest of a Waller County, TX inmate found dead in her jail cell.
Sandra Bland was arrested July 10 during a traffic stop.
The DPS trooper who arrested her says she was combative.
Bland was found hanging by a plastic bag in her jail cell last week.
Her death was ruled a suicide, but her family disputes that.
DPS released video from the traffic stop Tuesday after a meeting between Bland’s family and state leaders.
Waller County District Attorney Elton Mathis said at a news conference Monday that a Texas Rangers investigation into her death is being supervised by the FBI.
“It is very much too early to make any kind of determination that this was a suicide or a murder because the investigations are not complete,” Mathis said.
He said he’s asked the Texas Rangers to do extensive scientific testing for fingerprints, touch DNA and use any other valid investigative techniques “so we can figure out and say with certainty what happened in that cell.”
“This investigation is still being treated just as it would be in a murder investigation. There are many questions being raised in Waller County, across the country and the world about this case. It needs a thorough review,” Mathis said, noting, “It will go to a grand jury.”
