Crump, who is representing the Grier family, said Grier had a history of mental health crises and the family had called the police several times in the past. “When they came home, they called an ambulance,” said Grier’s father, Marvin Grier. “The ambulance service was coming out and taking her to the hospital for help.” “But this time they only called the police and the police didn’t bring the ambulance with her, even though Mrs. Mary (Brianna’s mom) clearly stated that she was having an episode,” Crump explained. Crump said Hancock County sheriff’s deputies entered the home, handcuffed Grier and placed her in the back of a patrol car to take her into custody for allegedly resisting arrest. In the body camera video released by the Georgia Bureau of Investigation, Grier asks deputies to breathalyze her and repeatedly tells officers she is not intoxicated. According to a timestamp on the video, Grier was placed in the patrol car shortly before 1 a.m. on July 15. Grier then yells at the officers that she will hang herself if they put her in the car. They proceed to handcuff her and attempt to place her in a squad car, but when she resists further, an officer appears to unfurl his taser.
When Grier sees this, she yells at the cops that they can see her and that she doesn’t care. The officer responds, saying he’s not going to test her. The video shows the officer dropping the Taser and then walking away from the rear driver’s side door. When the officer returns, he is seen picking Grier up off the ground and putting her in the back seat of the patrol car. The body camera video does not show whether the officers opened, closed or had any interaction with the rear passenger door, but one officer can be heard asking another officer if the door is closed. GBI investigators concluded Wednesday that “the rear passenger door of the patrol car, near where Grier was sitting, was never closed,” according to a news release. Less than a minute later, after officers pulled away from the Grier family’s home, the video shows an officer suddenly stop his vehicle and get out. Once out of the car, the officer spots Grier lying face down on the side of the road. Grier doesn’t answer the officer, who taps her side and says her name. The officer then radios a patrol car behind him that they will need an ambulance. The video does not show the moment Grier falls from the vehicle, but it does show her face first on the ground and the rear passenger car door open. The second officer says Grier is still breathing. Grier never responded to the officers calling her name after she fell out of the patrol car. The video ends with Grier on the ground as police wait for paramedics. Crump alleges that police did not secure Grier in a seat belt while she was handcuffed in the back of the police car and as a result, when the vehicle began to move, she somehow fell out of the car, landing on her head, fracturing her skull her. and then fell into a coma for six days before dying of her injuries. Investigators reviewed multiple body camera videos, conducted numerous interviews and performed “mechanical tests on the patrol car” to determine “if there were any possible mechanical malfunctions” in the vehicle, the GBI statement said. The GBI press release notes that two deputies were trying to put her in the back of the patrol car after she was arrested and handcuffed. Grier told deputies she was going to hurt herself and was on the ground refusing to get into the patrol car, according to the release. The GBI release said the two deputies and Grier, who was on the ground, “were in the rear driver’s side door of the patrol car” when “one of the deputies walked up and opened the rear passenger door.” The same deputy quickly returned to the passenger door, the GBI statement says, and both deputies put Grier in the back of the patrol car. The deputies closed the rear driver’s side door and, according to the GBI release, “Investigation indicates the deputy thought he closed the rear passenger door.” In the video, an officer can be seen picking up Grier and placing her in the car from the rear driver’s side door. Off camera, one of the officers is heard asking if the door on the other side is closed, to which the other officer says yes. Deputies left the scene and drove a short distance before Grier fell out of the moving car, according to the release. CNN reached out to the Hancock County Sheriff’s Department for comment, but did not immediately hear back. “I just don’t understand why they couldn’t put a seat belt on her because they violated so many policies to prevent this from happening,” Crump said. “We loved her regardless, unconditionally. Now we have to raise these kids and tell them a story, and I’m not going to tell any lies,” Marvin Greer told reporters Friday. “I want to tell the truth so it won’t happen to anyone else.” CNN’s Zenebou Syllaand and Camila Moreno-Lizarazo contributed to this report.
