(CNN) -- Mexican security forces engaged in a prolonged shootout with heavily armed suspected cartel members in Sinaloa state Thursday, in an operation that ensnared a son of imprisoned drug lord Joaquin "El Chapo" Guzman.Mexican federal troops had initially detained Ovidio Guzman Lopez, 28, in the northern city of Culiacan, in what Mexico's State Security Secretary Cristoban Castanillo called a "federally-coordinated operation."But Security Minister Alfonso Durazo has told Reuters that he was later released, saying the decision was taken to protect lives.Suspected members of the powerful Sinaloa drug cartel appeared to overpower the security forces during the shootout, who later suspended operations.According to CNN affiliate ADN40, armored vehicles with military-grade machinery exchanged heavy artillery against federal troops in Culiacan, in the heart of Sinaloa.The shootout forced many residents to flee in panic, others remained locked in their homes while outside, troops engaged in intense gun battles throughout the day. Residents have been asked to stay inside and schools have been closed until further notice, officials said, according to ADN40.Images on social media appeared to show the terror unleashed on the inhabitants of Culiacan. Plumes of black smoke billowed on the horizon while on the ground, mothers coddled their children while searching for cover behind parked cars.Late Thursday Durazo said government operations in Culiacan had been suspended following a violent back and forth between federal entities and criminal groups.Durazo said that law enforcement officers and members of the Mexican National Guard were conducting a routine patrol when they were attacked by people inside a home in the city at around 3:30 p.m. local time (4:30 p.m. ET).The patrol unit fought back and took control of the house, finding four occupants inside. Authorities identified one of the occupants as Ovidio Guzman Lopez.During the confrontation, other members of an organized criminal group arrived on scene, with more firepower than authorities. Violent attacks also erupted in different parts of the city creating "a situation of panic," Durazo said.With the "purpose of safeguarding the security and tranquility of the Culiacan society, the officials of the Cabinet of Security agreed to suspend said actions."Who is Ovidio Guzman Lopez?Ovidio Guzman Lopez is the son of Guzman and his second wife, Griselda Lopez. He is believed to have a large role in the Sinaloa cartel, according to the US Treasury Department.In February, Ovidio Guzman Lopez was charged with conspiracy to distribute drugs to be imported into the US, along with his brother Joaquin Guzman Lopez, 34, by the US Department of Justice.Prosecutors said that from April 2008 through April 2018, the brothers conspired to distribute cocaine, marijuana and methamphetamine from Mexico and other places to be imported into the US.In July, their father -- the once-powerful leader of the Sinaloa cartel -- was sentenced to life in prison plus 30 years in the US.Guzman was convicted in February on 10 federal charges, including murder conspiracies, running a continuing criminal enterprise and other drug-related charges.He was considered the most "powerful drug trafficker in the world" by the Treasury Department and his criminal enterprise spanned continents and triggered bloodshed throughout his native Mexico.In 2015 he dramatically escaped from prison, riding on a motorcycle through a tunnel that had been dug to his cell at the Altiplano maximum security federal prison.Ray Donovan, the DEA special agent who spearheaded the 22-agency effort that led to Guzman's capture, told CNN in February that the Sinaloa cartel still supplies the vast majority of US drug markets."In fact, Chapo's sons are now risen through the ranks of the Sinaloa cartel and taken over Chapo's end of the organization," he said. 3909

  

(CNN) -- Scientists have discovered a "monster black hole" so massive that, in theory, it shouldn't exist.It's a stellar black hole — the type that forms after stars die, collapse, and explode. Researchers had previously believed that the size limit was no more than 20 times the mass of our sun because as these stars die, they lose most of their mass through explosions that expel matter and gas swept away by stellar winds.This theory has now been toppled by LB-1, the newly-discovered black hole. Located about 15,000 light years away, it has a mass 70 times greater than our sun, according to a press release from the Chinese Academy of Sciences.The findings were published by Chinese researchers in the journal Nature on Wednesday."Black holes of such mass should not even exist in our galaxy, according to most of the current models of stellar evolution," said Liu Jifeng, head of the team that made the discovery. "LB-1 is twice as massive as what we thought possible. Now theorists will have to take up the challenge of explaining its formation."Scientists are now scratching their heads at how LB-1 got so huge.The Chinese team has proposed a number of theories. LB-1's sheer size suggests that it "was not formed from the collapse of only one star," the study said -- instead, it could potentially be two smaller black holes orbiting each other.Another possibility is that it formed from a "fallback supernova." This is when a supernova -- the last stage of an exploding star -- ejects material during the explosion, which then falls back into the supernova, creating a black hole.This fallback formation is theoretically possible, but scientists have never been able to prove or observe it. If this is how LB-1 formed, then we may have "direct evidence for this process" for the first time, the study said.LB-1 is not the biggest black hole ever discovered -- but it may be the largest of its kind. There are several types of black holes, and stellar black holes like LB-1 are on the smaller side, according to NASA. Supermassive black holes are much bigger -- they can be billions of times the mass of our sun.Scientists believe supermassive black holes may be connected to the formation of galaxies, as they often exist at the center of the massive star systems -- but it is still not clear exactly how, or which form first.Stellar renaissanceStellar black holes are believed to be commonly scattered across the universe, but they are difficult to detect because they do not normally emit X-rays -- only doing so when they gobble up gas from a star that has ventured close enough. They are so elusive that scientists have only found, identified, and measured about two dozen stellar black holes, the press release said.The researchers at the Chinese Academy of Sciences tried a different approach. Instead of looking for X-rays emitted by black holes, the team looked for stars that were orbiting some invisible object, being pulled in by its gravity.Their efforts paid off -- they soon spotted a giant star eight times heavier than the sun, orbiting around what turned out to be LB-1."This discovery forces us to re-examine our models of how stellar-mass black holes form," said David Reitze, a physicist at the University of Florida. In May, Reitze's team made its own breakthrough discovery -- observing the never-before-seen collision of a neutron star and a black hole, which sent out ripples in space and time.These twin discoveries -- the collision, and now LB-1 -- indicate that scientists are reaching "a renaissance in our understanding of black hole astrophysics," said Reitze in the press release.There have been several other discoveries over the past year that have added to this renaissance. In October, researchers discovered what they believe to be a new type of black hole, smaller than the other kinds. And earlier this week, astronomers discovered a black hole that is actually helping baby stars grow instead of destroying them. 3971

  

(CNN) -- Police in Long Beach, California, are mourning a K9 officer that died apparently of heat-related causes in a department vehicle.The dog, Ozzy, was found by its handler when both were off-duty about 3:40 p.m. on August 14, the Long Beach Police Department said in a statement."This unfortunate incident was not intentional," the statement reads. "Preliminarily, we believe this was an accident and we are taking all the necessary steps to avoid this happening in the future."The department said its K9 vehicles have "fail/safe equipment that is meant to generate an alert," but it might not have been working, the statement said. The department statement said K9 handlers are checking their heat system controllers before every shift.A veterinarian examined Ozzy. "The preliminary results determined the cause of death to be heat related," the police statement said.The high temperature that day in Long Beach was 89 degrees, National Weather Service records show.Police did not identify Ozzy's handler."Our department is mourning Ozzy's loss as we would with any of our employees. Our K9's are an indispensable part of our department, and we will continue to view them as our partners."The Humane Society says it's never safe to leave pets locked in cars."It doesn't have to be that warm outside for a car to become dangerously hot inside," the organization's website says. "When it's 80 degrees Fahrenheit outside, the temperature inside your car can heat up to 99 degrees Fahrenheit within 10 minutes." 1521
