Bryan Kohberger trial: Is the knife sheath a smoking gun?
In the upcoming Bryan Kohberger trial, the so-called 'smoking gun' may be DNA found on a knife sheath next to one victim's body. Though the defense is trying to discredit it, prosecutors say it's key. Kohberger's homes in Washington and Pennsylvania were searched, revealing items including black clothes, gloves and criminology books — none definitive alone, but telling when combined. NewsNation's Brian Entin spoke with top experts about what it all means.

Supreme Court to hear case on IQ tests and death penalty next term
The Supreme Court will hear a case next term centered on the role of multiple IQ scores in determining an Alabama murderer's eligibility for the death penalty, according to a list issued by the court late Friday. In Hamm v. Smith, the state of Alabama is arguing that Joseph Smith — who was sentenced to death for a murder in 1997 — should be executed because he has not proved that his IQ is 70 or below, as required by state law. However, the U.S. District Court for the Southern District of Alabama vacated Smith's death sentence after ruling he is intellectually disabled because the score on one of his IQ tests could fall below 70 when accounting for margin of error. Smith had obtained five IQ scores that ranged from 72 to 78. The Supreme Court justices agreed to hear Hamm v. Smith to determine a limited question: 'Whether and how courts may consider the cumulative effect of multiple IQ scores in assessing an Atkins claim,' referring to the 2002 landmark decision Atkins v. Virginia, which ruled that executing those with intellectual disabilities violates the Eighth Amendment's ban on cruel and unusual punishment. In November, the Supreme Court issued a per curiam decision to remand the case for further consideration. In it, the justices said that the U.S. Court of Appeals for the Eleventh Circuit — which had affirmed the lower court's decision to vacate Smith's death sentence — had been unclear in why it had issued that decision. In February, the state of Alabama again asked the Supreme Court to intervene, saying the Eleventh Circuit 'watered down the most objective prong of the test, overrode Alabama's definition of intellectual disability, and shattered Atkins's promise to leave meaningful discretion to the States.' 'This case was not close: Smith scored 75, 74, 72, 78, and 74 on five full-scale IQ tests. There is no way to conclude from these five numbers that Smith's true IQ is likely to be 70 or below,' the state of Alabama argued, also adding that evaluating multiple IQ scores is 'complicated' and that the Supreme Court has not specified how to do it. 'Smith could take hundreds of IQ tests, score 75 on all of them, yet his IQ still 'could be' 70, according to the panel [the Eleventh Circuit], because every test could have erred by 5 points. The panel failed to appreciate that multiple tests together can provide a more accurate estimate than each test alone,' the state argued. The Supreme Court's next term is scheduled to begin in October. The list of new cases was not expected until Monday morning, but email notifications about the list were inadvertently sent Friday evening because of a technical glitch, so the court chose to release the list of cases earlier than scheduled. In a statement that accompanied the early release, court spokeswoman Patricia McCabe said the notifications were sent prematurely because of an 'apparent software malfunction.' Justin Jouvenal contributed to this report.

After Chicago police officer accidentally killed by fellow officer, top cop urges against rush to judgment
Chicago Police Supt. Larry Snelling on Saturday cautioned against a rush to judgment, after police confirmed Officer Krystal Rivera was accidentally shot and killed by a fellow officer Thursday night during a chase in the Chatham neighborhood. "There may be things that an officer sees that no one else knows at the time," he said. Rivera was part of a CPD tactical team on patrol just before 10 p.m. near 82nd and Drexel, when they tried to conduct an investigatory stop, and as officers approached, the suspect ran into a nearby apartment building. Police chased the suspect inside, and sources said Rivera and her partner followed the suspect to an apartment on the second floor. Snelling has said, when officers got to that apartment, they were confronted by a second person armed with a rifle. "As released in yesterday's preliminary statement, an officer discharged his weapon during the encounter with an armed offender," the department said in a statement Friday night. "Further investigation revealed the only weapon discharged during this incident was the weapon of the officer, whose gunfire unintentionally struck Officer Rivera." Rivera, 36, was shot in the back, and was rushed to University of Chicago Medical Center, where she was pronounced dead. Police have not released any information about the other officer's name, age, or time with department, but sources said the officer is Rivera's partner, and Snelling has given some insight into his situation. At an outreach event to build bridges between police officers and Chicago youth on Saturday morning, there was no avoiding the trauma and tragedy of the past 48 hours. "That officer is in a very, very tough place; unimaginable what that officer has to be feeling right now," Snelling said. Although police have confirmed another officer accidentally shot and killed Rivera, Snelling urged Chicagoans not to jump to any premature conclusions about exactly what happened. "There may be things that an officer sees that no one else knows at the time," he said. Dr. Carrie Steiner, a former Chicago police officer turned police and public service psychologist, said the human brain works differently under extreme stress. "We're trying to do the best job we can, but sometimes it's maybe not the best, right?" she said. "When you're faced with deadly force, your limbic system starts to go, and you are just like more of an animal, and you're just reacting to things. … You're not using the frontal lobe, which is what we're using right now. You're using the limbic system, which is basically fight, flight, freeze." These situations are rare but not unprecedented. Two Chicago Police officers were wounded in 2021 when another officer's gun discharged during a struggle with a suspect. Snelling said the investigation will likely result in changes at the department. "This is how we create training and anything else that we need to do around these situations," he said. Purple and black bunting hung across the entrance of CPD headquarters on Saturday in honor of Rivera, a four-year veteran of the force, and a mother. No funeral services or other memorial arrangements for Rivera have yet been announced. No charges have been filed against either of the people in custody. Former Chicago Police Supt. Garry McCarthy, now chief of police in Willow Springs, said this investigation could take longer than others, because of the complicating factors involving multiple officers. Chicago police and the Civilian Office of Police Accountability were investigating the shooting.

Colorado man who used pill presses to make, sell fentanyl sentenced to 145 years
A Colorado man was sentenced to 145.5 years in state prison Friday after police discovered six pill presses, two 3D-printed semi-automatic guns, and baggies of fentanyl pills and cocaine powder scattered throughout his Aurora residence last year. The jail term for 33-year-old Tashon Roberts was ordered four months after a Denver jury convicted him on four counts related to the manufacture, possession and distribution of fentanyl. The jury also found Roberts guilty of child abuse for each of the three children who were living in the home at the time of his arrest. One of the children tested positive at a local hospital for fentanyl through a urine sample, according to the arrest affidavit in Roberts's case. The home was one of two in Aurora which Denver prosecutors believed Roberts and his team produced millions of fentanyl pills -- as many as six-hundred thousand per month -- between January and August of 2024. The pills were distributed throughout the Denver metro area, as stated by the Denver District Attorney's Office in a press release. The home in the 1800 block of Olathe Street in Aurora that was raided in May 2024 by local and federal agents as part of a fentanyl pill manufacturing operation. A 33-year-old man, Tashon Roberts, was sentenced Friday to 145.5 years in the Colorado Department of Corrections. CBS Denver police officers, the Aurora SWAT team, and agents from both the U.S. Drug Enforcement Administration Homeland Security Investigations donned protective suits and raided Roberts's home and drug "laboratory" in the 1800 block of Olathe Street on May 1, 2024. Aside from three pill presses found in a room dedicated to that process, others were found in a closet and in the unfinished garage. Some of the presses had white powder loaded in the hoppers. Plastic baggies of fentanyl pills were found throughout the home. Once was floating in the toilet tank, according to the affidavit. Roberts and three other adults were taken into custody. The three children were turned over to Arapahoe County Department of Human Services. That raid occurred two months after a woman was questioned by Denver officers after she left the home. Officers began conducting surveillance on the home after receiving tips from other drug case defendants. The woman arrived in an Uber, according to the affidavit. When she left, an unknown black man walked to curb and looked both ways along the street, presumably looking for any law enforcement vehicles following the Uber. The surveilling officers avoided detection and managed to pull over the Uber driver for not using a turn signal. The woman in the rear passenger seat was arrested for drug possession and also named Roberts and others in the Olathe home as her suppliers of several years. Tashon Roberts following his arrest last year on drug charges. Denver District Attorney's Office One of Roberts's companions in the Olathe drug-making operation was 35-year-old Coleman Phillips. All but one felony drug distribution charge against Phillips was dropped in October of last year. He was release on a $500 cash bond. He has not been sentenced yet. Another adult arrested as a result of the Olathe raid was Imani Hale. The 29-year-old pleaded not guilty to felony drug and child abuse charges in April. She is scheduled for jury trial in September. The fourth adult from the Olathe raid was not identified in the affidavit. An HSI agent in El Paso, Texas, provided Denver investigators with information about Roberts's purchase of at least one pill press from a China-based website in 2021 and 2022. The website, was sanctioned in 2023 by the U.S. Department of Treasury's Office of Foreign Assets Control and shut down. The die molds or stamps from the pill presses in the Olathe home were removed by a Denver detective. They showed an imprint of "M30," reflecting the crew was producing counterfeit oxycodone pills. The presses were destroyed by the Aurora Fire Department and disposed of, per the affidavit. The second Aurora home used as part of the team's pill production was not referenced in the original affidavit, suggesting investigators did not discover it until after Roberts was arrested. "We are pleased to hear that Mr. Roberts, who knew that what he was doing greatly endangered lives in our city, will be off the streets for many years," stated Denver Police Chief Ron Thomas after Roberts was found guilty. "The warning 'One Pill Can Kill' is absolutely true, and the dismantling of this fentanyl pill-making operation has potentially saved lives by ending a significant supply of fentanyl pills into our community. Our investigators did an incredible job uncovering the operation and those behind it, and we will continue aggressively pursuing anyone manufacturing or dealing illicit narcotics in Denver."
