Texas officials have released a new version of a dashboard camera video of a traffic stop of a black woman later found hanging dead in her jail cell and said a version released earlier had technical issues but had not been edited.

The video, released publicly late on Tuesday, shows how the stop of Sandra Bland for a failure to signal a lane change quickly escalated into an altercation between her and a state trooper. Footage in which a car or a tow truck driver are suddenly seen in different places or gone raised questions about whether the video had been altered.

"Yesterday's video was not edited," Tom Vinger, a spokesman for the Texas Department of Public Safety, said in a statement, adding that the technical issues from the Tuesday release had been resolved in the new version.

Vinger said the department has asked the FBI to examine the dashcam video and jail video to ensure their integrity.

The entire video was uploaded Tuesday to include the audio and video of the conversation the trooper had by telephone with his sergeant after the arrest, Vinger said.

Bland, 28, who was from the Chicago area, was pulled over on July 10 near Prairie View, Texas, northwest of Houston. She was taken into custody and charged with assaulting an officer. She was found hanging in her jail cell on July 13 with a plastic trash bag around her neck.

Her death was originally ruled a suicide, although officials have said they are handling it as a murder probe. But Bland's family, while acknowledging her previous struggles with depression, has dismissed the idea she was suicidal.

The attorney for the woman's family said in an email Wednesday the family had flown home to Chicago, taking her body on the same flight, in preparation for her funeral on Saturday.

The state trooper, Brian Encinia, has been put on desk duty for violating protocol.

Demonstrators have protested outside the jail where Bland died, and her case has been taken up by activists who say it is the latest example of racial bias and excessive force by U.S. law enforcement. The trooper involved in the incident is white.

The 49-minute video uploaded on Wednesday shows Encinia approaching the car and asking if Bland is irritated. Bland says she is upset about being stopped for such a minor issue.

The trooper later asks Bland to put out her cigarette, which she refuses to do, setting off an argument that leads to Encinia pointing a Taser at her and shouting: "I will light you up."

Bland asks at least 10 times about why she is being arrested before Encinia replies she is resisting arrest.
