Teen arrested in fatal New Year's Day crash charged as adult

Daniela Benavides San Miguel, 18, killed in Key Biscayne crash

MIAMI – A 17-year-old boy who was arrested in a deadly New Year's Day crash in Key Biscayne was formally charged as an adult Wednesday.

Isaias Medina was arrested last week on multiple charges, including reckless driving causing serious injury, vehicular homicide and driving without a license.

Miami-Dade police said Medina was speeding in a Porsche on Harbor Drive when he lost control of the car near a curve and struck several trees before crashing into the front gate of a home.

Detectives said he was driving 60 mph in a 30 mph road.

Medina's back seat passenger, Daniela Benavides San Miguel, 18, was killed in the crash. Benavides San Miguel had graduated from Gulliver Preparatory last spring and was a freshman at Pepperdine University in California.

A passenger in the front seat, Mathew Saldana, 17, was injured in the crash.

According to detectives, Saldana said he and Medina were party hopping throughout Key Biscayne on New Year's Eve in a golf court.

He said he later took Benavides San Miguel and Medina to his house for a joyride in his family's silver Porsche convertible.

According to court documents, Medina was behind the wheel of the convertible and his blood had traces of marijuana and Xanax in it.

Miami-Dade County Judge Mindy Glazer set Medina's bond Wednesday at $100,000.

"He has shown a tremendous amount of remorse," Medina's attorney, David Kubilian, told reporters outside of the courtroom. "It's been a very very difficult time for the victim's family, and I also think it's been a very difficult time for my client's family as well."

If Medina bonds out of jail he will be placed under house arrest and fitted with an ankle monitor. He will also be required to undergo regular drug tests and is not allowed to drive.
