FORT LAUDERDALE, Fla. -- A Miami-Dade police officer who was relieved of duty amid allegations that he covered up his role in a fatal hit-and-run crash last year surrendered to authorities Monday afternoon.

Detective Michael Alayon is charged with leaving the scene of a crash involving death.

According to the Florida Highway Patrol, Ryland Nye, of Pompano Beach, was rear-ended as he drove west on Interstate 595 near Flamingo Road on Oct. 10. Nye's vehicle hit a guardrail and flipped over, ejecting Nye. He was killed instantly when two other vehicles ran over him.

The driver of the Lexus that hit Nye's sport utility vehicle took off on foot, the FHP said, but the car was registered to Alayon.

Police went to Alayon's house hours after the wreck and found him there. The officers said Alayon told them he had been at his girlfriend's house earlier and that his house had been burglarized and his car stolen. But, according to court records, the 28-year-old had several bruises and cuts consistent with the crash.

Alayon, a four-year veteran of the Miami-Dade Police Department, had no comment as he turned himself in to police. He was charged following a two-month joint investigation by the state attorney's office, FHP and Miami-Dade police.

Nye's family has filed a civil lawsuit against the detective, hoping to find out what really happened that night.

"It's sad because the charges that the state attorney can bring against him are limited because he left (the scene)," attorney Walter Campbell Jr. said. "Could we have had a vehicular manslaughter?"

Alayon has been relieved of duty pending the outcome of the investigation.

Nye was buried Oct. 15 at Forest Lawn North Cemetery. His wife, three daughters and five grandchildren survive him.

"I am going to make sure that justice is done," Nye's daughter, Tandie Jones, said.
