JACKSONVILLE, Fla. -- The friends and families of four young people came together Monday evening to mourn their loved ones.
More than 100 people gathered in front of the Murray Hill home where Derek Williams, his best friend Gontrell Hagans, and two sisters Keshell and Keyonna Brown were shot Thursday night.
Their killer is still unknown four days later.
"Whoever did this, please turn yourself in," said Sabrina Johnson, Williams' aunt.
Johnson said Williams was more than generous to strangers and that he cared deeply for his three young children.
"His daughter is in pain," Johnson said as she clutched Williams' 11-year-old daughter. "His family is in pain. You have destroyed us."
Family of Gontrell Hagans said he was also a loving father to four kids.
"He loved them so much. That was his pride and joy, and he didn't deserve to get killed like that," said Avea Myers, mother of Hagan's eldest son.
Myers says Hagans called her around 9 p.m. Thursday to finalize plans for their son's 8th birthday party that Saturday. He planned to take all four of his children to the fair to celebrate.
"That's something he did with all of them every year and they loved it."
Instead of having a party, Myers says his family is now heartbroken an planning a father's funeral.
"I'm so sorry for all four victims. These parents have to bury their children instead of children burying their parents and that's hard."
Detectives continued to gather clues from the scene Monday. Not long after opening the property again, more than 100 people stopped by to pay their respects to Williams, Hagans and the Brown sisters.
"I cant imagine my nephew knew someone capable of doing something like this," said Johnson. "I just pray someone who knows something will come forward."
