First Coast News spoke with Casey Gibson about Delapaz's arrest.  He was a wrestling coach to Bell, Delapaz and Raulerson at Sandalwood High School. 

He considered them all 'great students' and says, "I know it hasn't gotten easier for us because I think about them all the time. I was very honored to be their coach. I was honored to know them."

FHP also revealed that the four who died weren't wearing a seatbelt.

He was arrested in Jacksonville and booked into the Duval County Jail with a bond of $950,000, Jacksonville Sheriff's Office records state.

Delapaz was charged with two felonies -- DUI manslaughter and DUI serious bodily injury -- and two misdemeanors -- DUI and DUI property damage/personal injury. He was also charged with vehicular manslaughter. His first court appearance is Saturday at 1 p.m.

Elly Littlejohn, the mother of Alysia Littlejohn, released the following statement following the news of Delapaz's arrest:

"Today, we were notified of the arrest of Blake Delapaz in connection with the tragic crash that killed my baby Alysia Littlejohn and 3 of her friends last June. It has been a long and difficult wait for the family to learn of the results of the Florida Highway Patrol’s investigation. Although the next couple of months will be difficult, we stand with the other families in seeking justice for the senseless deaths of loved ones. In the Blink of an Eye tragedy can happen and it’s important for those responsible to be held accountable. We hope that this will serve as a cautionary tale for other young people to avoid driving wrecklessly and drinking and driving. As well as getting into a car with anyone under the influence. We ask to keep all of our families in your prayers as we travel down this journey for justice. "
