Colorado mass killing suspect moved to new jail facility over threats to his safety

Authorities have transferred Ahmad Al Aliwi Alissa, the suspected murderer charged with gunning down 10 people at a Boulder, Colorado, supermarket on Monday, to a new facility following threats to his safety.

What are the details?

According to the New York Post, Alissa, 21, remains in custody of the Boulder County Sheriff's Office but is being housed in a correctional facility outside the county after he was reportedly targeted with threats.

The suspect appeared in court Thursday morning. He faces 10 counts of first-degree murder and one count of attempted murder. The outlet reported that Alissa, a Syrian native, will also face additional charges, which are undetermined at the time of this reporting. Prosecutors, according to the Post, will file "additional charges" in the coming weeks.

He did not enter a plea during the Thursday hearing.

"Defense attorneys requested evidence and a witness list from the prosecutors, and asked the judge for a three-month trial delay so they could look into 'Mr. Alissa's mental illness,'" the outlet reported. "Prosecutors said they have not yet received evidence from police, who are still processing the King Soopers grocery store crime scene."

What else?

The Post on Friday revealed that Alissa passed a gun background check ahead of the massacre that took the lives of 10 people.

"A store where the suspect in the Colorado supermarket massacre bought his gun reportedly said the sale was lawful after he passed a background check," the outlet reported.

Alissa purchased a Ruger AR-556 at the Eagles Nest Armory in his hometown of Arvada on March 16.

The store's owner, John Mark Eagleton, said that he is "shocked" by what happened.

"We are absolutely shocked by what happened and our hearts are broken for the victims and families that are left behind," Eagleton said. "Ensuring every sale that occurs at our shop is lawful has always been and will always remain the highest priority for our business."

He added, “We have and will continue to fully cooperate with law enforcement as their investigation continues."
