The family of Sandra Bland, the Illinois woman found dead in a Texas jail cell last month, filed a lawsuit Tuesday in Houston seeking to hold people involved in her death accountable. “We are looking for Waller County and the individuals involved to take accountability,” said attorney Cannon Lambert Sr., who is representing the family.

The lawsuit is filed against Trooper Brian Encinia, the sheriff of Waller County, Texas, two of the jailers and the Texas Department of Public Safety, Lambert said.
