A community is left mourning, wondering, how did an 18-year-old high school student ended up shot dead on a baseball field.

"I looked down, then I seen a body," said Eliezer Perez. "Then I ran to the bus stop and I told them. Then we all came back and looked at it. We thought it was fake at first, but then we noticed it was real, so we called the cops."

Schoolchildren found the body of David Arango on a baseball field in the 1000 block of Scott Street in Reading's Oakbrook neighborhood Thursday morning.

Police said an autopsy determined he suffered a gunshot wound to the head. The coroner has ruled his death a homicide.

Thursday night, Arango's family spoke out exclusively with 69 News. Understandably, they want answers.

"It's unexplained," said his sister, Diana Arango. "I don't see why him. He was social, very loving."

It was also a shock for the children who found his body.

"[I] was walking down," said Perez. "I looked over and he was wearing a jacket. He was like face down with his arm out. I don't know why his pants were down."

When loved ones visited the site, all that was left was the indentation in the damp ground left by Arango's body, now filled with rain water.

Fabio Munoz, Arango's uncle, splashed the water on his face, saying, "I love you. I love you."

He told 69 News he knows, sooner or later, whoever did this will pay.

Investigators said Arango lived nearby.

Detectives are not sure sure if he was killed at the scene or if his body was dumped there, although police said there was a blood trail leading from the sidewalk down the adjacent embankment where the body was found.

Authorities said there were no reports of gunshots.

Friends said Arango, a junior at Reading High, always dressed nicely and that may have made him a target.

The family said Arango's sudden death makes no sense. David's sister had a plea for the police.

"I want them to find who it was who did this to him because it's terrible," said Diana Arango.

Police said Arango suffered a head wound.
