What we know about the controversy in Sandra Bland's death

Story highlights

  • Sandra Bland, 28, was found dead in a Waller County jail cell in Texas
  • Authorities say Bland hanged herself
  • Bland's family questions the circumstances of her death

(CNN)Newly released video showing the arrest of a woman who later died in police custody has added fuel to the fire over the controversy surrounding her death.

The dashcam video reveals how a Texas state trooper initially pulled Sandra Bland over for allegedly failing to use her turn signal and how the situation then escalated.
    While Bland's jailhouse death is being handled in the manner of a murder investigation, authorities in Texas initially said the 28-year-old woman appeared to have killed herself.
    But why would a young woman who just landed a new job at her alma mater take her own life?
    Here's what we know about Bland's death at the Waller County jail in Hempstead and the events leading up to it:

    Why did the officer stop and later arrest her?

    Bland was arrested on July 10 and accused of assaulting an officer after a traffic stop, police said. A trooper pulled her over for allegedly failing to signal a lane change.
    During the stop, Bland became "argumentative and uncooperative," according to the Texas Department of Public Safety.
    Authorities on Tuesday released dashcam video of the July 10 traffic stop, revealing new details about a case that has captured national attention.
    An attorney for her family, Cannon Lambert, told CNN that the officer asked Bland to get out of her car after she refused to put out her cigarette. The officer opened the driver's side door and asked Bland to get out, he said.
    The video shows the Texas trooper threaten Bland with a Taser and say: "I will light you up!"
    Cell phone video purporting to show part of Bland's arrest was posted online. CNN could not verify the video was of Bland's arrest, but Lambert said there was "little reason to believe that it's not her."
    The video shows an officer using his knee to hold a woman down on the ground. The woman is heard saying that she can't "feel my arm" and that the trooper "slammed my f------ head to the ground."
    "Do you not even care about that?" she asked.
    Sharon Cooper, one of Bland's sisters, told CNN that preliminary autopsy results showed her sibling suffered "deep tissue bruising to her back" consistent with someone pushing a knee into her back.
    Waller County paramedics were called to the scene of her arrest, but Bland refused a medical evaluation before she was booked, according to the Public Safety Department.
    Asked about reports that Bland kicked the trooper before her arrest, Lambert said: "It's not characteristic that she would voluntarily and without any sort of provocation strike out at someone."

    Who was Sandra Bland?

    Bland was taking a new job at Prairie View A&M University in Texas, more than 1,000 miles from her home in the Chicago suburb of Naperville, Illinois.
    She had graduated from the historically black college in 2009 and was returning there as a student ambassador, according to family members.
    In the weeks before her death in police custody, Bland regularly used the #SandySpeaks hashtag to post videos on Facebook in which she denounced police brutality and racism.
    "Being a black person in America is very, very hard," she said in a video posted in April. "At the moment black lives matter. They matter."

    How did Bland end up dead in her cell?

    Bland was found dead in a Waller County jail cell on July 13 after she hanged herself with a plastic trash bag, authorities said.
    There were no cameras inside Bland's cell, but cameras in the hallway outside showed no one entering or leaving before her body was discovered, Waller County District Attorney Elton Mathis said.

    "We cannot find where anyone goes into the cell from the hallway to do her any harm from the last time she was physically viewed alive," the prosecutor said.
    Bland was found "in her cell not breathing from what appears to be self-inflicted asphyxiation," a Sheriff's Office statement said. Bland received CPR, and an ambulance was called, but she was pronounced dead a short time later.
    "Any loss of life is a tragic incident and, while the investigation is being conducted by outside agencies, the Waller County Sheriff's Office will continue to observe the daily operations of the jail to always look for improvements and/or preventions of these incidents," the statement said.
    Bland apparently refused a breakfast tray about 6:30 that Monday morning, according to the Sheriff's Office.
    When a guard checked on the prisoner a half-hour later, Bland reportedly said, "I'm fine," according to the Sheriff's Office.
    At 8 a.m., Bland apparently asked to make a phone call from her cell, the Sheriff's Office said. There is no record of her making a call.
    Bland was found at 9 a.m., hanging in her cell, according to the Sheriff's Office.
    Trash bags have been removed from all cells at the jail, and inmates are being checked on hourly, according to the Sheriff's Office.

    What's the controversy about?

    Those who knew Bland question that she would commit suicide.
    "Based on the Sandy I knew, this is unfathomable to me," Cooper, Bland's sister, said of her hanging. "People who knew her, truly knew her, the depth of her, that's unfathomable right now."
    Another sister, Shante Needham, said her sibling called her from jail the Saturday before the death was reported.
    Needham said her sister told her that a trooper had held her down with his knee on her back before her arrest and that she thought she had fractured her arm.
    "She was very aggravated," Needham said. "She seemed to be in pain."
    Holding back tears, Needham added: "I told her I would work on getting her out."
    Lambert said the family was securing the 10% of Bland's $5,000 bail for her release.
    "We don't understand this," the lawyer said of her death. "It doesn't make sense."
    Cooper said she can't believe her sister took her own life.
    "To know Sandy was to love her," she said. "She was someone who was extremely spontaneous, spunky, outgoing, truly filled with life and joy. So when you think through the circumstances shared with us through this point, this is unimaginable."
    Mathis, the prosecutor, said: "Ms. Bland's family does make valid points that she did have a lot of things going on in her life that were good."
    But investigators were examining online videos posted by Bland in March in which she talked about battling depression and post-traumatic stress disorder, according to Mathis.
    Cooper said that her sister hadn't been diagnosed with either depression or PTSD and that her video message was intended to be inspirational to people feeling the same way.

    Who is investigating her death?

    The investigation is being treated like a murder investigation, according to Mathis.
    "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," he said Monday. "This is being treated like a murder investigation."
    The case will go to a grand jury.
    "There are too many questions that still need to be resolved," he said.
    The Texas Rangers and the FBI are investigating Bland's death.
    "The death of Sandra Bland will not be swept under the rug," Mathis said. "There will be no one who is protected. ... The truth will come out."

    What happened to the police officer who arrested her?

    In a statement, the Texas Department of Public Safety said the officer involved in Bland's arrest was assigned to administrative duties pending an investigation.
    "We have identified violations of the department's procedures regarding traffic stops and the department's courtesy policy," the department said in the statement.
    Texas Department of Public Safety Director Steve McCraw told reporters Tuesday: "A DPS state trooper has an obligation to exhibit professionalism and be courteous throughout the entire contact, and that wasn't the case in this situation."

    Why has Bland's death drawn national attention?

    For many people, Bland is one of the latest victims of what they say is widespread racial bias and police brutality in the country. Since her death, posts with the hashtag #JusticeForSandy and #WhatHappenedToSandyBland have gone up on Facebook and Twitter.
    She was not the only black woman to die in custody last week.
    The day after Bland's death, authorities in Alabama said, 18-year-old Kindra Chapman died after hanging herself in the Homewood City Jail. She had been arrested on a charge of first-degree robbery, accused of robbing a person of a cell phone, al.com reported.
    The close timing of the two deaths under similar circumstances struck a chord with some social media users, who took to Twitter to share directives for what to do "if I die in police custody."
    "We don't want to see Sandy politicized," said Lambert, the attorney for Bland's family. "We don't want to see her life politicized, and we don't want to see her death politicized."
    He added, "A lot of people are saying that there was foul play. We don't know that there was. We don't know that there wasn't."
