While the man pointed his gun at fellow students, Gross and two others ran toward him from different directions.
One of the others was Tracy Bridges, a Buncombe County sheriff’s deputy from Asheville, who also had his gun, Gross said.
When the gunman saw them, Gross said, he put his weapon down and his hands up.
The third man, Ted Besen, who has worked as a police officer in Wilmington, was not armed and ordered the gunman onto the ground. Instead, the gunman lunged at Besen, punching him in the face.
That’s when a fourth student ran up and tackled the gunman. Gross and Bridges jumped on the gunman, pulled his hands behind his back and held him as he tried to fight them off.
When the gunman was under control, Gross ran back to his car for his handcuffs
Contrast that with the story you linked above
Third-year student Ted Besen crept along the side of the building toward Odighizuwa, who had just come outside from the lounge. Gross sprinted for his car, about 100 yards away, and retrieved a bulletproof vest and a 9 mm handgun. Back home in North Carolina, he’s an officer with the Grifton Police Department.
He ran back, gun in hand.
By then, Odighizuwa had placed his gun and a clip on a light fixture about four feet off the ground and put his hands in the air. He was yelling something unintelligible to the students, Besen said. Besen, a former Marine and Wilmington, N.C., police officer, told him to get onto the ground.
