"Pickell said that about 20 rocks were found strewn on the highway and that the teens allegedly went to eat at a McDonald's after throwing the rocks".
The suspects face up to life in prison, but White Sr. - the victim's father - says that's not enough.
White was pronounced dead at a nearby hospital.
White, who lived in Mount Morris Township, enjoyed sports, video games and the outdoors, according to an obituary, which said he was born in nearby Flint but lived in SC for most of his life.
Anger, who is accused of dropping the rock that struck White, is being held in the Genesee County Jail.
Kyle Anger, 17, Mark Sekelsky, 16, Mikadyn Payne, 16, Alexzander Miller, 15, and Trevor Gray, 15, have been charged with second-degree murder.
Police said the group threw a tire and about 20 rocks, one weighing 20 pounds, off two overpasses that night, damaging several vehicles. The driver said he saw a large rock crash into the windshield of the passenger side and hit White in the face, then richocheted from his face to his chest, according to Genesee County Sheriff Robert Pickell. They pleaded not guilty to the charges on Tuesday. Arraignments are expected Tuesday morning.
Investigators believe the suspects also threw tires and auto engine parts over another overpass nearby and damaged several other vehicles. The other four are 15-years-old.
Amy Cagle had to tell her 5-year-old son that his father was killed coming home from work. "I don't think anybody is laughing and I think that if there's any warning that both David and I can give, is telling young people, you make a bad decision, you could be spending the rest of your life in prison".
After the arrests, White's fiancee Cagle told ABC12 that she hoped the teenagers realize what they had done, "how many lives they torn apart, and know that what they did was wrong". But the incident that took White's life was no accident, authorities said.
