Four years ago, 18-year-old Jose Rosario Jr. was shot and killed in his own home. The case is still unsolved.

Those close with Rosario met to honor his memory.

"It's just kind of shocking what happened to him, y'know?" said his father, Jose Rosario Sr. "It's a tragedy."

The memorial service was held in Burton Park, his favorite park, where Rosario Jr. played basketball as a child.
