CHARLOTTESVILLE, Va. – The suspect in the University of Virginia shooting that left three people dead and two wounded was part of the class field trip that ended in tragedy Sunday night, a university spokesman said Tuesday.

UVA’s Brian Coy said suspected gunman Christopher Darnell Jones Jr., 22, was a member of a group of about two dozen who traveled 120 miles by bus to watch a play in Washington, then returned to campus.

“Someone amongst them chose to do an act of violence” when the bus got back around 10:30 p.m., university Police Chief Timothy Longo said. Officers responding to a report of shots fired found the bodies on the bus, he said.

Police said Jones, a former player on the school’s football team, opened fire inside the bus and killed three current team members while wounding two other students, at least one of them also a football player.

Juniors D’Sean Perry, Lavel Davis Jr. and Devin Chandler were identified as the victims. Running back Mike Hollins, also a third-year player, was one of two people wounded in the attack, his mother said.

Ryan Lynch, a second-year student on the trip, told Philadelphia TV station KYW the suspect pulled out a gun as they arrived back and pushed one of the now-deceased football players, saying, “You guys are always messing with me.”

“They just kept coming, more and more gunshots – just wouldn’t stop,” Lynch said, adding the gunman then “just sort of walked or skipped off the bus.”

The rampage prompted a 12-hour campus lockdown while police pursued the shooter. Jones was arrested Monday morning in Henrico County, Virginia, near Richmond. He faces three charges of second-degree murder and three charges of use of a firearm in the commission of a felony. Jones is scheduled to be arraigned Wednesday.
