The Latest on the ongoing investigation of the Las Vegas shooting

The Las Vegas shooter has pleaded not guilty to murder and other charges in connection with the deaths of 58 people at the Route 91 Harvest Festival, a popular music festival in the United States that was the nation’s biggest gathering of music fans for years.

The Associated Press is not naming the victims, citing their families’ requests.

A federal judge is expected to rule on Monday whether to release the first person charged in the killings, including one who was found guilty of first-degree murder.

It could take weeks before the judge will make his decision.

The judge is scheduled to make his ruling Tuesday.

The trial of the second man charged with first-and-third-degree killing will begin Monday in Las Vegas federal court, where his lawyer is seeking to delay the trial to allow for more time to prepare his client for trial.

Authorities say the gunman killed himself during the massacre, which occurred at a crowded music festival known for its live music and socializing.

Authorities said the gunman fired more than 200 rounds at a crowd of about 1,000 people at a Route 91 music festival that is near the state’s main tourist attraction, the Las Cruces Strip.

He was killed by law enforcement and the gunman himself.

He killed himself at the end of the concert, which began about 10:30 p.m. local time, the day of the attack, and then turned his weapon on himself.

He killed himself in his hotel room, police said.
