During President Donald Trump’s meeting with Chinese President Xi Jinping at the G-20 summit last Saturday, the two leaders agreed to curb the flow of the synthetic opioid fentanyl to the United States. 

A White House announcement said Xi agreed to label fentanyl a controlled substance so that sellers of the drug would be “subject to China’s maximum penalty under the law,” which is the death penalty. The Trump administration called the move a “wonderful humanitarian gesture”: Opioid overdoses, often involving fentanyl, led to more than 70,000 American deaths in 2017.

Prosecutors said Wednesday they will seek the death penalty for a U.S. Border Patrol agent who confessed to murdering four prostitutes. A grand jury indicted Juan David Ortiz, 35, on capital murder charges in the string of killings that occurred in September.

A grand jury on Friday indicted a former Dallas police officer for murder in the killing of her unarmed black neighbor in his apartment. Amber Guyger, who is white, was arrested on a manslaughter charge three days after the Sept. 6 shooting of her upstairs neighbor, Botham Jean, a 26-year-old who worked for the accounting and consulting firm PwC. Guyger told investigators that after finishing her shift, she returned home in her uniform and parked on the fourth floor of her apartment complex’s garage, rather than the third floor, where her unit was located.

Four people, including two medical workers, a police officer, and the suspected gunman, were killed after an argument turned into a shooting at a Chicago hospital Monday. Police spokesman Anthony Guglielmi described the shooting as a “domestic-related active shooter incident.” The alleged attacker, Juan Lopez, was arguing with emergency room physician Tamara O’Neal, 38, outside Mercy Hospital on Chicago’s South Side when he pulled out a gun and fatally shot her.

Reports of crimes motivated by racial, religious, sexual, and other prejudices spiked across the United States by 17 percent in 2017, rising for the third straight year, with a 37 percent increase in anti-Semitic crimes, according to an FBI report released Tuesday. Some of the increases might be the result of better reporting by police departments, but law enforcement officials say they don’t doubt hate crimes are on the rise. A little more than two weeks ago, an anti-Semitic, anti-immigrant gunman killed 11 people in a Pittsburgh synagogue as they gathered for Saturday services.

A police officer fatally shot a security guard who had subdued a suspect following a shooting in a bar outside Chicago on Sunday, prompting a lawsuit from the guard’s family. The security guard, Jemel Roberson, was working at Manny’s Blue Room bar in Robbins, Ill., when an alleged assailant opened fire following a dispute. When police arrived on the scene, Roberson was pinning the suspect to the ground outside the bar.

Two high school coaches who worked with Ian David Long, who shot and killed 12 people Wednesday at a bar in Thousand Oaks, Calif., said he was volatile and had behavioral problems that went unaddressed by school administrators. Long, 28, was a Marine machine gunner and Afghanistan war veteran. Police confirmed Sunday that an autopsy determined he died from a self-inflicted gunshot wound.
