The 22-year-old University of Virginia student suspected of killing three football players and wounding two other people was facing school disciplinary action after UVA officials learned he failed to disclose his conviction last year on a misdemeanor concealed weapons charge, a school spokesperson says.

Christopher Darnell Jones Jr., a former football player, faces three counts of second-degree murder and three counts of using a handgun in the commission of a felony, UVA Police Chief Tim Longo said Monday.

He also faces two counts of malicious wounding, each accompanied by a firearm charge, Albemarle County prosecutor James Hingeley said Tuesday.

Jones and the victims had just returned from a school field trip in Washington, DC, late Sunday when the victims were gunned down on and near a bus on the Charlottesville campus, officials said.

The shooting claimed the lives of UVA football players Devin Chandler, Lavel Davis Jr. and D’Sean Perry, university president Jim Ryan said.

Now, with the suspect in custody, attention has turned to the school’s past dealings with him – including an investigation this fall into comments he made about having a gun.

On Wednesday, a gun shop owner said Jones had twice tried to buy a gun – once failing a background check – before buying a handgun and a rifle in separate purchases this year.

Jones was the subject of a pending case with the university’s judicial council when Sunday’s shooting unfolded, officials said.

“On September 15, in the context of reviewing a potential hazing issue, UVA Student Affairs heard from a student that Mr. Jones made a comment to him about possessing a gun,” university spokesman Brian Coy said.

That person “did not see Mr. Jones in possession of a gun,” and the “comment about owning a gun was not made in conjunction with a threat,” Coy said.

“In the course of their investigation, University officials spoke with Mr. Jones’ roommate, who gave no indication of the presence of any weapons. In the course of their investigation, University officials discovered that Mr. Jones previously had been tried and convicted of a misdemeanor concealed weapons violation in 2021, for which he received a 12-month suspended sentence and a small fine.”

Throughout the investigation, Coy said, “Mr. Jones repeatedly refused to cooperate with University officials who were seeking additional information about the claims that he had a firearm and about his failure to disclose the previous misdemeanor conviction.”

So on October 27, “the Threat Assessment Team escalated his case for disciplinary action,” Coy said.

The school’s judicial council took over the case, and the results are pending, UVA Police Chief Timothy Longo Sr. said.

Jones was also involved in a hazing investigation on campus that was closed because witnesses would not cooperate, Longo said.

The motive behind the killing of three UVA Cavaliers remains a mystery, the university’s president said.

Jones was taken into custody Monday afternoon in Henrico County, about 80 miles east of Charlottesville, authorities said. His arrest ended an hours-long manhunt that prompted an overnight lockdown on UVA’s campus, with about 500 people sheltering in classrooms and libraries, Longo said.

In 2018, Jones was a freshman running back but didn’t play in any games, according to his biography on the athletics department website. A university spokesperson said he joined the team, but an old injury prevented him from practicing, and Jones went through rehabilitation and treatment. It was Jones’ only season as part of the team.
