One of Dunn's roommates finally answered. The roommate didn't believe his story until he saw the blood, Dunn recalls. Rather than call 911 and wait for an ambulance, the friend loaded him into a car and drove to the hospital.
At the hospital
Steve Delice took Dunn under his wing at Coppin, where they were both members of the track team. After graduating early from high school in Jamaica at age 15, Dunn had become listless, a "highly educated bum," as he puts it. He played basketball and computer games for two years before being pulled by his father to Staten Island.
There, he struggled to find purpose, working in construction until an uncle pushed him to resume running. At the Empire State Games in 2007, he beat an All-American. Delice took notice and worked to get him to Coppin, where they developed a friendly rivalry.
"I'm going to surpass you in every way, Steve," Dunn would say with a grin. Athletically gifted, exceedingly smart and blessed with a tremendous work ethic, Dunn was making good on the promise.
Now Delice was in the hospital awaiting word on whether Dunn would survive a shooting. It made no sense.
"He's not the type who would go looking for trouble," Delice said. "I couldn't rationalize it in any way, at all."
Ramsey, the athletic director, rushed to the hospital after getting a phone call. He reached out to Dunn's parents and started working with the Jamaican Embassy on arrangements to get his mother to Baltimore.
Ramsey had only read about Shock Trauma, which he regarded as a "place where miraculous things happen."
There, doctors learned that the bullet had traveled through the side of Dunn's chest and under his right arm. It hit his collarbone, bouncing off an artery to his brain and landing close to his spinal cord. Both of his lungs collapsed. His nerves were damaged.
"Three times they had to open me, to jump-start me," Dunn said. "They said I would never walk again."
Delice said it was sobering to see Dunn in the hospital, so weak and helpless. But Delice was also hopeful. That the sprinter had been able to get back to his apartment seemed to bode well.
Dunn, who wasn't supposed to regain consciousness for a month, was alert within a week. While still being fed through a tube, he requested a laptop so that he could keep up with classwork, Ramsey recalled.
He was walking in two weeks. Within three, he was out of the hospital.
Nobody was convicted in the case. Michael Anthony Jones III, 20, was arrested that December in connection with the shooting and, other than a gun violation, later found not guilty of all charges. He has no other criminal record, and his lawyer said the verdict in the Dunn shooting was fair.
Dunn just wanted to put the incident behind him. In January 2011, he started running and lifting weights again.
"In the back of my mind, I wasn't injured," Dunn said. "I do not know how not to run. That's my anger relief, my stress relief."
At the end of the spring semester, Dunn walked the stage and graduated summa cum laude with a degree in management sciences.
Photos from that day show him smiling with friends, his braids peeking out from his graduation cap. Around his neck, he wore the customary blue Coppin State kente stoles and two medallions denoting his academic achievements.
