Waller County Sheriff officials said they believe Bland died in her cell the morning of July 13, from asphyxiation with a trash bag, three days after she was pulled over for not using her turn signal and then arrested for allegedly assaulting an officer.

The Harris County medical examiner ruled her death a suicide. But Waller County District Attorney Elton Mathis said the 28-year-old’s death would be treated “just as it would be a murder investigation.”

“There are many questions that are being raised here in Waller County,” Mathis said. “It needs to be a thorough and exhaustive review.”

Most of those questions and conspiracy theories were dispelled on July 28, when prosecutors released video of Bland walking through the jail and posing for her mugshot during the booking process:

Before the video was released, the strongest evidence was Bland’s voicemail to a Texas friend, LeVaughn Mosley, from her cell. In the voicemail posted by WLS-TV, Bland said, “how did switching lanes with no signal turn into all of this?”
