"It just doesn't make sense for us not to have Quani. What did he do to deserve this?" asked Bruce.
Police said 26-year-old Lonnie Haynes was driving at a high rate of speed and lost control of his car while exiting the California Avenue off-ramp at Highway 99. The car rolled, killing Quani and 23-year-old Robert Jared.
The crash also severally injured Pulley's 5-year-old brother. All three were passengers in Haynes' vehicle.
Haynes pleaded not guilty to a pair of counts of vehicular manslaughter while intoxicated and causing great bodily injury.
Right after Wednesday's arraignment, a heated confrontation between families erupted in the hallway outside the courtroom. Startled spectators caught in the middle tried to remain out of harm's way as Kern County Sheriff's deputies quickly moved in to separate the two sides.
"I want justice for my nephew," said Mixon. "He did not deserve to die like that. My other nephew is fighting for his life."
The 5-year-old remains at Children's Hospital Central California in Madera.
Haynes is being held on bail of $915,000.
