Live from NPR News in Washington, I'm Windsor Johnston. Detectives are turning over the double homicide case against Nick Reiner to the Los Angeles County District Attorney's office at the sour he's accused of killing his parents, Hollywood director Rob Reiner and his wife Michelle. Steve Futterman reports. The 32 year old remains in jail after his arrest on Sunday.

[Steve Futterman]

The Los Angeles County District attorney is expected to get the case today. It's possible Rob Reiner's 32 year old son Nick may be formally charged with murder today. Yesterday, Louisiana Police Chief Jim McDonnell announced the arrest by robbery and homicide officers.

[Jim McDonnell / Scott Horsley]

They worked on this case and were able to take into custody Nick Reiner. He was subsequently booked for murder.

[Steve Futterman]

Right now, he is being held without bail. In the past, Nick Reiner has acknowledged struggles with numerous mental health challenges and substance abuse. For NPR News, I'm Steve Futterman in Los Angeles.

[Windsor Johnston]

The manhunt continues for the suspect who carried out a mass shooting at Brown University on Saturday, killing two students and injuring nine others. Zoe Weissman is a pre med student at Brown. In 2018, she attended a middle school next to Martin Marjory Stoneman Douglas High School in Parkland, Florida, where a former student shot and killed 17 people.

[Zoe Weissman]

I was honestly, I think that my reaction could have gone either of two ways because I've already been this through this before. I think I could have either reacted significantly worse than everyone else or reacted better. And I thankfully with the latter, I was surprised at the fact that my brain kind of knew what to do already. And I think that's because this is a situation that kind of plays in my head every single day.

[Windsor Johnston]

Authorities in Rhode island have released three new videos of a man they believe is responsible for the deadly shooting. Hiring slowed last month as U.S. employers added just 64,000 jobs. NPR's Scott Horsley reports. The unemployment rate rose to its highest level in four years.

[Jim McDonnell / Scott Horsley]

Health care and construction were some of the only industries to add jobs in November. Factories cut jobs and so did delivery services. The pace of hiring has slowed sharply since the beginning of the year. Concern over a weakening job market led the Federal Reserve to lower its benchmark interest rate last week for the third time since September. The Labor Department's ability to monitor the job market was hampered this fall by the six week government shutdown. Both the October and November jobs numbers were delayed, and the survey used to track unemployment was not conducted in October. The unemployment rate for November was 4.6%. That's up from 4.4% in September and the highest jobless rate since the fall of 2021. Scott Horsley, NPR News, Washington.

The lawsuit claims the BBC misrepresented Trump's remarks by combining separate portions of the speech, calling the broadcast false and misleading. Teachers across the country are turn turning to detection software to figure out whether students have done their own schoolwork or used artificial intelligence to do it for them. Reporter Lee Gaines explains there's just one problem. The software doesn't always work.

[Carvana Announcer / Lee Gaines]

Numerous studies show several of the most popular AI detectors flagged some things as AI generated that weren't, and vice versa. Nonetheless, NPR found that some school districts from Utah to Florida to Ohio are spending thousands of dollars on these tool. John Grady teaches English at Shaker Heights High School outside Cleveland. He knows AI detectors aren't perfect, but one thing he likes about the software.
