One of the neighbors in the apartment complex where Botham Shem Jean was shot and killed by a Dallas police officer revealed that she recorded a video of what happened right after the incident. She posted the footage on her Instagram, where it went viral. The video shows a female police officer crying as she talks to someone on the phone in the hallway of the South Side Flats, at 1210 S. Lamar Street.

In the next footage, 26-year-old Jean can allegedly be seen being wheeled on a gurney through the hallway, with an EMT on top of him giving CPR. The video shows police officers and paramedics walking up and down the corridor. Till Saturday, law enforcement in Dallas had not provided any confirmation on the released footage.

The Dallas Police Department identified the female officer as Amber Guyger in a tweet on Saturday night. Her identity was kept a secret for legal reasons before Lee Merritt, the attorney representing the Jean family, identified her publicly. Having said that, Guyger's name had already started making rounds on social media since Friday.

26-year-old Jean was shot to death by an off-duty, uniformed Dallas Police officer Thursday night at around 10 pm after she mistook his apartment for her own. But it is still unclear how the cop got into the apartment, why she thought it was hers, or if they had a history.

Dallas Mayor Mike Rawlings and state Sen. Royce West held a press conference on Saturday afternoon, asking for Dallas residents to be patient and let authorities complete their investigation. “Is this a white on black crime? Yes,” West said. “It was a white, female Dallas police officer who shot and killed a person from St. Lucia of African descent. Is this a race-related crime? Don’t know. I would hold any type of decision you make on what happened until all of the facts come in.” According to him, the door was ajar and the officer was easily able to get inside Jean's residence, the Star-Telegram reports.

“We need to find out whether there was a personal relationship,” West said. “There are so many facts that need to be looked at before determining what kind of homicide this is.”

Dallas Police Chief Renee Hall said on Friday that they were working on a warrant to charge the officer with manslaughter. The following day, Merritt said the family was still waiting for the warrant to be issued. “The warrant that seemed to be looming was withdrawn,” Merritt said. “From everything we’ve heard, we’re not sure exactly what happened. Everyone we’ve spoken to today provides enough evidence for a charge of manslaughter ... there is likely evidence for an even stiffer penalty.”

According to Sara Mokuria, a co-founder of Mothers Against Police Brutality, Dallas police should not be perceived in such a way. “We want full transparency,” she said. “We would like the name of the officer to be released publicly and we would like the district attorney to act swiftly and give us immediate charges ... We know that there have been calls for peace, but peace does not come without justice, and so in this moment we are calling for justice.”

Jean did not know Officer Guyger, Merritt said, denying rumors related to the same floating on the internet. “We have nothing to substantiate those claims,” he said. “Certainly no one that has been attached to the family or any of the law enforcement officers we’ve spoken to can confirm that, in fact, they say just the opposite.”

On Sunday, Guyger was arrested in Kaufman County and booked into the Kaufman County Jail, the Texas Rangers said in a statement. Guyger was released Sunday night on $300,000 bail, NBC Dallas-Fort Worth reported.
