Two weeks ago, Brianna Grier was arrested for public drunkenness. According to GBI investigators, she fell out the rear passenger side door of Hancock County deputy cruiser. The GBI says the deputy thought he shut the door before he drove off. Officers found Grier laying face down in the grass on the side of the road with critical head injuries. At the news conference, Brianna Grier's father, Marvin Grier says he wants the full truth.
"We ain't trying to start no problem, but we're going to start a problem because we want to know what happened," Marvin Grier said.
Brianna Grier had a history of mental illness and drug abuse. During the news conference, her father said that doesn't matter.
"We loved her regardless, unconditionally. Now, we got to raise these kids and tell them a story, and I don't plan on telling them no lie," Marvin Grier said.
Brianna Grier was first injured on July 15, early in the morning. Her father told 13WMAZ her birthday was the day before. She died six days later on July 21 at Grady Memorial Hospital in Atlanta.
Friday night, the Georgia Bureau of Investigation tweeted that they will be releasing the bodycam video of the incident after agents review it along with Grier's family.
