Updated 8:15 p.m. Saturday: Revised to include officer's name.

Dallas police identified the officer who killed 26-year-old Botham Jean in his own home late Thursday as Amber Guyger, but they had yet to charge her late Saturday.

Mayor Mike Rawlings said earlier in the day that he supported Police Chief U. Renee Hall's handling of the shooting's aftermath and her decision to call in state investigators.

"It's important that the citizens know that I believe what Chief Hall has done has been exactly the right thing. This is a tough situation," Rawlings said at a news conference at Paul Quinn College. "For anyone that questions whether we're going to get to the truth of this, there should be no doubters. We will find out exactly what happened."

The unusual police shooting has prompted international interest and led to an outpouring of support for the Saint Lucia native's heartbroken friends and family, some of whom came to Dallas on Saturday and met with officials and attorneys.

Botham Jean, 26, was a graduate of Harding University in Arkansas, where he had been a beloved worship leader.

The Police Department withheld the officer's name until after 8 p.m. Saturday — hours after The Dallas Morning News identified her as Guyger. Guyger's attorney declined to comment.

Guyger was off duty but still in uniform after working a shift when she arrived Thursday night at the South Side Flats, police said. She told police she mistakenly thought Jean's apartment was her own and fatally shot the PricewaterhouseCoopers employee.

Guyger, a Dallas officer since November 2013, wasn't injured. Authorities said more police arrived within four minutes after the shooting was reported. Jean was pronounced dead at Baylor University Medical Center.

Police had said Friday that they were seeking an arrest warrant for manslaughter in Jean's death.

But the chief said Saturday that a judge had not signed a warrant because the Texas Rangers, who were interviewing the officer, had learned new information and wanted to investigate further before any warrant was issued.

The chief declined to disclose the new information.

Jean family attorney S. Lee Merritt called for a swift arrest and the filing of charges. He said the officer was receiving preferential treatment.

Merritt, flanked by Jean family members and representatives from Mothers Against Police Brutality, said Saturday that they were "not asking for anyone to jump to any conclusions or asking for law enforcement to convict this person or to deny them their right to due process."

Instead, he said, the family wanted the officer "to be treated like every other citizen, and where there is evidence that they've committed a crime, that there's a warrant to be issued and an arrest to be made."

Investigation continues

Despite the ongoing investigation, no law enforcement presence was visible Saturday at the apartment complex.

Apartments in the sprawling complex have identical gray paint, silver peepholes and electric locks. Each apartment is identified by its number in lights on the wall beside the unit's tan door. Jean's had a distinctive red doormat in front of it Saturday.

Typically, Dallas police investigate a shooting by one of their own. But Hall said Saturday that she and her department would no longer have roles in the criminal investigation. She declined to say whether the department was conducting a parallel inquiry.

The chief said there should be "no secrets" about what happened.

"There is no blue line; those things cannot exist," she said. "I want you to hold me and my organization accountable for what we're supposed to be doing."

Rawlings called Hall "foresighted" for asking the Texas Rangers to investigate.

Dallas Police Association President Mike Mata also called Saturday for "an open, transparent, full investigation of the event" and said that "if the grand jury deems necessary, this officer should have to answer for her actions in a court of law in Dallas County."

'A potential leader'

Mata had kind words for Jean, a native of Saint Lucia in the Caribbean.

"Mr. Jean was an amazing individual, and he is what us as parents hope our children turn out to be," he said.

The mayor said he had met with the slain man's relatives Saturday morning. Calling them remarkable, he said Jean's mother had told him that her son "loved everybody" and "didn't really see color in what he was doing."

Rawlings called the slain man "exactly the sort of citizen we want to have in the city of Dallas."

When the Trump administration imposed a travel ban that stranded many immigrants at airports across the United States, Jean delivered water to protesters at DFW International Airport.

"Not only has he lost his life, but we've lost a potential leader for this city for decades to come," the mayor said.

He called Jean's mother "amazingly graceful" in the face of grief.

"She wasn't wagging her finger at anybody. She was saying, 'What happened?'" Rawlings said.

He said she told him: "I'm not angry. I'm heartbroken. And I just want to make sure all the truth is told."

Rawlings said he had also offered his condolences to Saint Lucia's prime minister, who planned to visit Dallas this week to meet with him.

"I do know that I can choose what attitude I take about things going forward, and we can hopefully, hopefully turn that positive spirit that Botham had into a thing that makes us a better city," the mayor said. "It doesn't look like we can right now because it's so painful and it looks problematic, but that's what his mother wants."

Black-and-white questions

State Sen. Royce West, D-Dallas, asked people to keep Jean's family in their prayers while authorities search for answers.

"Is this a race-related crime? Don't know. There's a lot of questions that are still out there," said West, who also spoke at Saturday's news conference. "So I would hold any type of decision that you make concerning what transpired until all of the facts come in."

Jean was black, and Guyger is white.

West said he wanted the officer to face appropriate charges and expressed confidence in the Rangers as he called on them to "leave no stone unturned."

The Dallas County district attorney's office is also conducting an independent investigation, as it always does with shootings by officers.

In less than a year, juries in the county have convicted two police officers of murder.

Last month, a jury convicted Roy Oliver for the on-duty shooting of 15-year-old Jordan Edwards. Jordan was a passenger in a car Oliver fired into with a rifle as it drove away in Balch Springs. The same jury sentenced Oliver to 15 years in prison. Oliver is white and Jordan was black.

In December, another jury convicted Ken Johnson for a shooting committed while he was off duty and out of uniform. Johnson, who was a Farmers Branch police officer, chased down and shot two teens he caught breaking into his SUV at his Addison apartment complex. Johnson fired 16 times into the car, killing 16-year-old Jose Cruz and seriously wounding Edgar Rodriguez, who was also 16. Johnson was sentenced in January to 10 years.

Staff writers Loyd Brumfield, Tristan Hallman and Sara Coello contributed to this report.

Correction: This story has been updated to say that Ken Johnson was a Farmers Branch police officer. It originally said he was an officer in Addison. That is where the shooting occurred.
