Laser-toting archaeologists have discovered an entire new city in the Central American jungle.

National Geographic reported Thursday that researchers have uncovered proof that Mayan civilization was far more advanced than previously thought. Using laser-created scans of the jungles in northern Guatemala, researchers "digitally removed the tree canopy" from images of the area, National Geographic explained. The editing — made possible by a technology called LiDAR, which scans pictures taken at a birds'-eye view — allowed researchers to peer beneath the dense fauna.

The result was the discovery that the jungles were concealing a Mayan "megalopolis" in their shadows. Underneath the leaves, researchers found more than 60,000 structures that were previously unknown, including "houses, palaces, [and] elevated highways," National Geographic reported. The structures likely created a series of connected cities.

The new discovery prompted the researchers to revise up previous calculations of the Mayan population. Scientists have long estimated that Mayan civilization had about 5 million inhabitants, but one archaeologist said the LiDAR findings indicate that number is way too low: "With this new data it's no longer unreasonable to think that there were 10 to 15 million people there," he said.

The LiDAR initiative is being led by the PACUNAM Foundation, a Guatemalan nonprofit that seeks to further research and preservation efforts in the region. And the search for Mayan ruins is far from over: Scientists leading the charge only scanned roughly 800 square miles of jungle in this initial sweep, and apparently still have more than 5,000 square miles to go.

Former Minneapolis police officer Derek Chauvin was found guilty on Tuesday of second-degree murder, third-degree murder, and second-degree manslaughter in the death of George Floyd, but there is still another trial on the horizon — this time for the three other officers who were part of Floyd's arrest last May.

As it stands now, the trial for former Minneapolis police officers J. Alexander Kueng, 27, Thomas Lane, 38, and Tou Thao, 35, is set to start on Aug. 23, with the men facing charges of aiding and abetting in the second-degree murder and second-degree manslaughter of Floyd. If convicted, they could face more than 16 years in prison. A hearing is scheduled for May 20 at the Minnesota Court of Appeals, with the state attorney general's office seeking to add a third-degree murder charge against Kueng, Lane, and Thao.

On May 25, 2020, the officers responded to a call at Cup Foods in Minneapolis, after it was reported that Floyd allegedly tried to pass a fake $20 bill. Footage of Floyd's arrest shows Chauvin with his knee on Floyd's neck for more than nine minutes, and prosecutors say Kueng, who graduated from the police academy in 2019, at one point was between Chauvin and Lane, kneeling on Floyd's back. When Floyd became unresponsive, Kueng checked for a pulse, and reported that he couldn't find one.

Lane, who had been on the police force for just a few days, was the officer who told Floyd to get out of his car, and placed handcuffs on him. Prosecutors say Chauvin, Kueng, and Lane all used their weight to keep Floyd on the ground, after he resisted attempts to get into the back of a police car. Lane asked at one point if they should roll Floyd over, and Chauvin responded, "No, staying put where we got him."

Thao, who rejoined the force in 2012 after being laid off, arrived at Cup Foods with Chauvin, after Floyd had already been handcuffed. Prosecutors say that while Thao did not have any physical contact with Floyd, he could see how Floyd was being restrained, and did not try to intervene.

All of the officers were fired and arrested following Floyd's death. Kueng, Lane, and Thao are now out on $750,000 bail. In January, their trial was split from Chauvin's due to COVID-19 safety precautions. Catherine Garcia

A police officer in Columbus, Ohio, shot a teenage girl Tuesday evening while responding to reports of an attempted stabbing. The girl, identified by family members and Franklin County Children's Services as Ma’Khia Bryant, 16, was taken to the hospital, where she was pronounced dead at 5:21 p.m. The Ohio Bureau of Criminal Investigation is investigating the shooting.

Bryant, who is Black, was shot at about 4:45 p.m., or 15 minutes before a Minneapolis jury returned guilty verdicts in the murder trial of Derek Chauvin, the white former police officer who killed George Floyd, who was Black. Protesters quickly gathered near the home where Bryant was shot. A woman who identified herself as Hazel Bryant, aunt of the victim, told The Columbus Dispatch that Ma’Khia Bryant lived in a foster home and got into an altercation with someone at the home. The aunt said her niece had a knife, but maintained she dropped it before the officer shot her.

Columbus officials Tuesday night released body-camera footage from the officer who shot Bryant. It shows the officer firing four shots as Ma’Khia Bryant as she appeared to swing the knife at another woman. The other people at the scene erupted in angry disbelief.

"We know, based on this footage, the officer took action to protect another young girl in our community, but a family is grieving tonight and this young 15-year-old girl [sic] will never be coming home,” Columbus Mayor Andrew Ginther said at Tuesday night's news conference. "It's a tragic day in the city of Columbus. It's a horrible, heartbreaking situation," he added. "We felt transparency in sharing this footage, as incomplete as it is at this time" was critical.

Interim Columbus Police Chief Michael Woods said BCI will be in charge of the investigation, and "we want to be sure that independent review from them, that we stay out of their way, and we provide the information that they request from us." Peter Weber

After being criticized for her remarks about George Floyd "sacrificing" his life "for justice," House Speaker Nancy Pelosi (D-Calif.) tried again on Twitter.

"George Floyd should be alive today," Pelosi tweeted on Tuesday evening. "His family's calls for justice for his murder were heard around the world. He did not die in vain. We must make sure other families don't suffer the same racism, violence, and pain, and we must enact the George Floyd Justice in Policing Act."

Pelosi appeared at a press conference with the Congressional Black Caucus shortly after former Minneapolis police officer Derek Chauvin was found guilty of murdering Floyd, a 46-year-old unarmed Black man. Floyd's death gained worldwide attention, sparking global protests against police brutality, and during her remarks, Pelosi thanked Floyd "for sacrificing your life for justice." She added that because of him and "millions of people around the world who came out for justice, your name will always be synonymous for justice." Catherine Garcia

Darnella Frazier, the teenager who used her cell phone to record George Floyd's arrest last May outside of Cup Foods in Minneapolis, wrote on Facebook that she "cried so hard" on Tuesday when it was announced that former police officer Derek Chauvin had been found guilty of murdering Floyd, an unarmed Black man.

Frazier, then 17 years old, had gone to the market with her younger cousin to buy a snack. The footage she captured showed Chauvin with his knee on Floyd's neck for more than nine minutes, and has been seen around the world, with many saying without it, Chauvin may have never been prosecuted. Frazier was one of the first witnesses to testify at Chauvin's trial, telling the court there have been "nights I stayed up apologizing and apologized to George Floyd for not doing more."

Per The Washington Post, Frazier wrote on Facebook Tuesday that before the guilty verdict was announced, "my heart was beating so fast, I was so anxious," and she thanked God for Chauvin being convicted on all charges. "George Floyd we did it!" Frazier wrote, adding, "Justice has been served."

After the verdict was announced, President Biden called Frazier "brave," as did Minnesota Attorney General Keith Ellison (D), who said Frazier and the other bystanders who pulled out their phones and started recording Floyd's arrest "performed simple yet profound acts of courage." Catherine Garcia

President Biden said it took "a unique and extraordinary convergence of factors" for former Minneapolis police officer Derek Chauvin to be found guilty of George Floyd's murder — a verdict that is "much too rare" when it comes to police brutality cases.

This was a "murder in the full light of day, and it ripped the blinders off for the whole world to see systemic racism," Biden said during a televised address. He praised the "brave young woman with a smartphone camera" who recorded Chauvin with his knee on Floyd's neck for more than nine minutes, and said the police officers who testified against Chauvin "instead of just closing ranks" should be "commended." It took all of that, plus a "jury who heard the evidence and carried out their civic duty in the midst of an extraordinary moment," to deliver "just basic accountability," Biden said.

Most men and women in law enforcement "serve their communities honorably, but those few who fail to meet that standard must be held accountable, and today, one was," Biden said. The verdict sends the message that "no one should be above the law," yet "it's not enough," and "in order to deliver real change and reform, we must do more to reduce the likelihood that a tragedy like this ever happens again."

Biden called on state and local governments, as well as the federal government, to "step up" and take action to fix the racial disparities in policing and the criminal justice system. He ended his remarks on a hopeful note, saying, "This can be a moment of significant change." Catherine Garcia

Vice President Kamala Harris on Tuesday evening urged the Senate to pass the George Floyd Justice in Policing Act, saying that it would "hold law enforcement accountable and help build trust between law enforcement and our communities."

The legislation should not be viewed as "a panacea to every problem, but as a start," Harris said during a televised address. "This work is long overdue. America has a long history of systemic racism. Black Americans and Black men in particular have been treated throughout the course of our history as less than human. Black men are fathers, and brothers, and sons, and uncles, and grandfathers, and friends, and neighbors. Their lives must be valued."

Racial injustice isn't just an issue for people of color, Harris said, it's "a problem for every American. It is keeping us from fulfilling the promise of liberty and justice for all, and it is holding our nation back from realizing our full potential. We are all a part of George Floyd's legacy and our job now is to honor it and to honor him." Catherine Garcia
