MIAMI (CBSMiami) – The family of a 16-year old Miami boy who died after he was shot over the weekend is asking for help in finding the person responsible.

“We are just looking for some answers on our son this Christmas,” said William Herrera of his son Bryan.

Bryan Herrera was riding his bike near 11th Avenue and 39th Street in Allapattah just after 11 a.m. on Saturday when he was shot in the head. He was rushed to the Ryder Trauma Center where he died.

His family said he was heading to a friend’s home and planning to work on a school project.

“That’s he said. That’s what he told us,” said the victim’s sister, Katherine Herrera. “He just wanted to finish up his school work.”

“We came out here for the community’s help,” William said. “We are trying to pick up the pieces. Our hearts are broken, our lives.”

Police say they have very little information on the gunman.

Herrera’s family said they want Bryan’s killer brought to justice.

“He has a soul. He was a great person. We loved him every day,” William said.

Miami Police said they have no description of the shooter, don’t know why William was shot and described the victim as a good kid who loved computer games and who was a straight A student with no criminal history.

Police searched Bryan’s belongings to fins some clues as to why someone might want to hurt him, but they found no such clues, just some game cards and sketches of comic book figures.

“He was a young kid full of life. He loved the family and now he’s gone,” Bryan’s brother said. “I just don’t want this to happen to anyone else. This was a bad dream.”

A police detective told CBS4′s Peter D’Oench, “This is innocence in the truest sense of the word. Unfortunately for the family, Christmas may never be the same again.

“Please, if you know anything, someone must know something, please call. Please help,” Bryan’s sister pleaded.

They urge anyone who knows something about the shooting to call Crime Stoppers at (305) 471-TIPS (8477).
