MIAMI (WSVN) - New video released, Tuesday, shows a Porsche speeding through a Key Biscayne neighborhood seconds before crashing into a light pole, claiming the life of a college freshman.

Seventeen-year-old Isaias Medina was arrested on New Year’s Day, after crashing the Porsche into trees, a lightpole and a gate on Harbor Drive, killing his backseat passenger, 18-year-old Pepperdine University student, Daniela San Miguel.

She died at the scene.

Witnesses on the scene of the crash, along the 700 block of Harbor Drive on Key Biscayne, described what they heard, which coincided with the audio on the surveillance video released Tuesday by the State Attorney’s Office.

“I heard a car speeding so fast that it sounded like a race track,” said a neighbor who heard the crash, “and then I heard, ‘Bang, bang, bang, crash.'”

“Speed was definitely a factor,” said Key Biscayne Police Chief Charles Press back in January. “Such a horrific impact that there was very little to protect the passengers that were inside the car.”

Medina, who was then a high school student, did not have a driver’s license at the time of the crash. He was charged with vehicular homicide following the fatal crash and was then placed on house arrest.

He was on house arrest until Nov. 2, when he was arrested a second time for tampering with his GPS ankle monitor. He was then placed behind bars.

On Tuesday, the State Attorney’s Office released footage from that day, recorded from a home near the crash site, which captured the silver Porsche speeding down the street. The video does not depict the crash.

This may just be the evidence prosecutors need to prosecute the then 17-year-old teen, who was driving.

His attorney hopes otherwise. “From day one, Isaias has expressed his remorse and the tremendous guilt he feels,” said attorney David Oscar Markus. “We are actively trying to resolve the case where he can accept responsibility for this tragedy.”

Medina will remain behind bars as he awaits trial. Medina has been charged as an adult and is expected in court on Wednesday for a status hearing.
