(10/23/2017) - Five teenagers from Clio are facing murder charges for allegedly throwing large rocks off an overpass onto I-75 last Wednesday.

Genesee County Sheriff Robert Pickell and Prosecutor David Leyton announced the charges Monday in a press conference.

The teens all have been charged as adults with second degree murder, conspiracy to commit murder, six counts malicious destruction of property and other crimes.

"It's not a prank, it's second degree murder," Pickell said. "I don't think anybody is laughing and I think that if there's any warning that both david and can give, is telling young people, you make a bad decision, you could be spending the rest of your life in prison."

One of the suspects is 17, while the other four are younger. Police say all five teens involved, who were arrested on Friday, attend Clio High School.

They will be arraigned Tuesday in 67th District Court before Judge Nathaniel Perry. If convicted of the most serious charges, they all face up to life in prison.

Police say they threw more than a dozen large rocks off the Dodge Street overpass onto southbound I-75 on Wednesday evening. A six pound rock crashed through the windshield of a van 32-year-old Kenneth White was riding in, killing him.

"To propel the size of boulder down from the Dodge Road overpass to a 70 mph vehicle that's headed southbound, you ought to know -- a reasonable person would know -- that that is creating a high risk of great bodily harm or in this case, death," Leyton said.
