Antonio Romanucci says the medical examiner who conducted an independent autopsy said Tyre's injuries are consistent with severe beatings.

He has called on people to look at the charges themselves and they will see that there is consistency and they were the maximum charges.

Crump has said the video has audio, and is very compelling as people will be able to see and hear for themselves what the officers did on 7 January.

Responding to questions, Crump says the district attorney watched the video of Tyre's arrest "blow by blow".

When you see the video, ask yourself what the correct charges are, he says.

Crump says those who see the clip - due to be released by Memphis police at 18:00 local time on Friday night - should ask themselves if the actions were intentional.

Asked about how to clean up the police department, Antonio Romanucci says it has to start with swift activity.

He says trust could be restored with real community policing, rather than suppression and racist policing - "that's where you can start", Romannuci adds.

He says the community wants this reform but the police unions don't want it.

"Call out the lawmakers in Washington," Romanucci adds, as he calls for federal change.

RowVaughn Wells is telling reporters more about her son.

She says Tyre Nichols like to go and watch sunsets, photography and skateboarding.

Those were his passions, she says adding that Tyre was a "beautiful son".

"No-one is perfect but he was close," she adds.

A lawyer for the family, Ben Crump, takes to the podium again as RowVaughn Wells breaks down in tears.

He says the officers charged have the right to bail and the family doesn't want to change the standards because they are black.

Crump adds that they want to see equal justice and the presumption of innocence applies to the officers.

Turning now to some questions someone asks RowVaughn Wells how she has been feeling.

She explains she was feeling a really bad pain in her stomach and when she found out what happened she felt that was the pain for her son.

RowVaughn says she has no clue how she feels right now.

No mother should go through what I'm going through right now, RowVaughn Wells says.

She says the pain of losing her child in such a violent way like Tyre's life was taken away is a pain many don't know.

"This was not supposed to happen, my son was supposed to be here today," Well continues.

"I'll always be with him," she says, as her son had a tattoo of her name.

"My son loved me to death and I loved him to death," Wells says, adding that the situation is "very difficult" for her.

Tyre Nichols' mother says her son always said he would be famous one day, "I did not know that this is what he meant"...

Holding her tears, she says the acts committed against her son were horrific.

RowVaughn Wells says she wants to ask for prayer, even for the five police officers.

She says the officers disgraced their own families, and she now prays for their families amid this tragedy.

RowVaughn thanks everyone for coming as people chant "justice for Tyre".

"I have a lot of words I wanna say but they're not coming out the right way," she says.

"I am still grieving and dealing with the death of my son.

"This was not supposed to happen."

RowVaughn Wells, Tyre's mother, now addresses those gathered in the Memphis church.

She reiterates that she has never seen the video showing her son's arrest, but adds that she's heard it's "horrific".

She urges people to not let their children see it.

Rodney Wells says he is happy Memphis Police Department Chief CJ Davis acted swiftly.

"We had a special case and a special son," he says.

He urges to protest but emphasise to protest safely.

Tyre Nichols' stepfather says he wants peace and for people to protest safely.

"Please protest, but protest safely," Rodney Wells says.

We're now hearing from Tyre's stepfather Rodney Wells, who says his main goal was initially to push for a Murder One charge against the officers.

However, he says he's now satisfied with the charges.

We are now hearing from the executive director of the Tennessee Women's Political Caucus who says her heart broke this morning when listening to Tyre's mother this morning.

"I was in tears all morning because of what happened," Vickie Terry says.

"Thank you for birthing Tyre.

"He is the individual who is going to turn this city around.

"Memphis is the blueprint for what is going to happen."

"We're going to make sure he did not die in vain," Van Turner says.

He adds that tonight will be one of the toughest nights for Memphis.

Turner says that the NAACP will stand with Tyre's family. We will stand united and peacefully protest, he adds.

"We will fight to the end...we will fight with all those who seek justice for Tyre," he says.

"We want to make sure that Tyre Nichols didn't die in vain."

We are now hearing from Van Turner who is the president of the Memphis branch of the National Association for the Advancement of Colored People (NAACP)

He starts by saying he is here for justice for Tyre and acknowledges this video will be "horrific".

We're now hearing again from Ben Crump, Nichols' lawyer.

"We don't hear about these things with our white brothers and sisters," Crump says.

"We don't see the videos of the police doing the most with white citizens," he adds.

Crump says we need to continue to speak about the police culture in the US.

As much as these five officers killed Tyre Nichols, Crump says, it was the police culture in America that killed Tyre Nichols.

Tyre just wanted to go home, Crump continues, referencing the kidnap charge against the officers.

"It's a traffic stop for God's sake...he was kidnapped for a simple traffic stop," he says.

Crump adds that this is "such an important case", adding that he continues to think about other black men who "ended up dead" after simple encounters with the police.

Back to Crump who points to the kidnap charge and Tyre's last known words before he died.

"His last words on this earth are 'mom, mom, mom', screaming for her," Crump says.
