Gun Violence

Twenty-one shots were fired at the scene. Police say the victim was shot about 10 times.

Detectives traced a vehicle one suspect drove to the scene to a Philadelphia home where they found the jewelry box, they said.

Luigi Mangione already was charged with murder in the Dec. 4 killing of Brian Thompson, but the indictment could help move along procedural steps toward extraditing him.

In a statement, the U.S. Marshals Service said security officers moved to stop the man after he entered the courthouse, brandishing a knife.

Philadelphia police said they plan to increase law enforcement’s presence outside City Hall in the wake of a triple shooting in Dilworth Park.

Deputy Commissioner Frank Vanore said police believe there was a fight near the ice rink prior to the shooting.

The U.S. Supreme Court is expected to weigh in on regulations on 3D-printed firearms after several states have filed lawsuits regarding their regulation.

Investigators have uncovered evidence that Luigi Mangione had prior knowledge UnitedHealthcare was holding its annual investor conference in New York City.

Social media posts from Luigi Mangione show the man suspected of killing Brian Thompson underwent successful back surgery last year that alleviated debilitating chronic pain.

It's an early pushback by mostly Democratic-led states against President-elect Donald Trump’s 2nd administration, which Platkin said “routinely sides with the gun industry."

Up to $60,000 in rewards from the FBI and the Crime Stoppers program had been offered to anyone calling in a tip leading to a break in the case.

Luigi Mangione is being held without bail in western Pennsylvania in the killing of Brian Thompson.

Suspect Luigi Mangione’s fingerprints also matched a water bottle and a snack bar wrapper that police found near the scene in Manhattan, Commissioner Jessica Tisch said.

Investigators are working to piece together why Luigi Mangione may have diverged from this path to make the violent and radical decision to gun down UnitedHealthcare's CEO.

The survey found that only 48 percent of city residents believe Philly police are doing a good job.
