"I'm very proud of him. He was a hell of a young man," Peter's father Thomas DiSabatino said.
Thomas DiSabatino spoke fondly of his one and only son who had just turned 20 on October 22.
"I think the tragedy of this whole thing is the potential of what he could've become is now gone and will never be repeated," DiSabatino said.
Residents of the apartment complex said last night around 9:15 they heard a loud argument near DiSabatino's car parked outside his first floor apartment at Studio Green West Apartment complex in the 200 block of Thorn Lane.
Moments later, they heard a series of gunshots coming from behind another building across the parking lot.
College students ran outside and saw their friend on the ground in a pool of blood with a gunshot wound to his side.
"I heard the shots and I seen him lying there. I didn't know what to think of the situation. Was he running for his life? I noticed his car was sitting here with a light on," friend Kyle Wilson said.
Dylan Brady and his brother performed CPR until paramedics arrived.
DiSabatino was taken to Christiana Hospital and pronounced dead.
"I did all I could do. It's just so sad," Brady said.
Police brought in a canine unit last night to search for suspects with no success. Friends of Peter DiSabatino came to his apartment earlier in the day after learning of his death.
They said they can't think of any reason anyone would want Pete dead.
"We all know him not to be anyone that would deserve to be shot, deserve to be robbed, deserve to be shot or any ill-will to happen to him. He was a great person and a great friend and everybody should know that," friend Olivia Natalini said.
Some of the friends graduated from Appoquinimink High School in Middletown, Delaware with DiSabatino in 2011.
Recently, he had been taking University of Delaware classes.
His father says he wanted to be a business entrepreneur.
"I just picked him up. We went to see the James Bond movie together. We had dinner afterwards. He told me what his plans were. He told me he wanted to be an entrepreneur. Maybe do a little bit of work in the entertainment business ," Thomas DiSabatino said.
Police say the suspects are described as two black men, one of whom was wearing a gray hooded sweatshirt and the other a black hooded sweatshirt.
DiSabatino's friends and family are hoping there will be answers and arrests soon.
