An attorney for Waller County says it will have a vigorous defense to a wrongful death lawsuit filed by the mother of Sandra Bland, the black woman authorities say hanged herself last month in the Texas county's jail.

Lawyer Larry Simmons says the county, while expressing sympathy to Sandra Bland's family, will be filing a response to the lawsuit Tuesday from Geneva Reed-Veal, and "will clearly articulate the county's legal position."

The lawsuit seeks unspecified punitive damages "for egregious acts and omissions" by the trooper who pulled Bland over for a traffic violation July 10 and then arrested her, as well as the Texas Department of Public Safety, Waller County, the sheriff's office and two jail employees.

The Department of Public Safety said it does not discuss potential or pending litigation.

An autopsy determined Bland hanged herself. Her family has disputed the findings, but acknowledged on Tuesday the possibility she killed herself.

10:30 a.m.

The attorney for the family of a black motorist who died while in custody in Texas says they need additional information from authorities in Waller County before they can complete their independent medical examination.

Cannon Lambert, the attorney for the family of Sandra Bland, spoke Tuesday at a news conference in Houston to announce the filing of a lawsuit against the Waller County sheriff's office and others. He said they are still waiting on many items from authorities regarding Bland's July 13 death in her jail cell, which authorities have said was a suicide by hanging.

He said, "We don't have the gastric content information. We don't have the ligature. We don't have the police reports. Candidly, we don't really know the time of death."

He said they also need to know what was done to try to help her.

Lambert added, "We don't even know all of the players involved. We don't know what the police reports reflect. We are getting bits and pieces of the toxicology report. We don't get the full toxicology report."

Since her death, authorities have released the findings of Bland's autopsy, her arrest affidavit, an initial toxicology report, surveillance video showing her in the jail, her jail intake records and the dash camera video of her traffic stop, which resulted in her arrest.
