FORT LAUDERDALE, Fla. -- A Miami-Dade police officer has been relieved of duty and could face criminal charges for allegedly covering up his role in a fatal hit-and-run crash last year, Local 10 learned Wednesday.

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.

"He would do anything for anybody," Nye's daughter, Candi Jones, said. "He always sacrificed to make sure everybody else was happy."

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 Miami-Dade police Detective Michael 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.

Local 10 has learned that the state attorney's office is considering criminal charges against Alayon and he was recently relieved of duty pending the outcome of the investigation.

"I just want him to be truthful and come forward," Jones said.

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

"I would be willing to wager that he'd been out drinking with his buddies and that what's caused the accident," attorney Walter Campbell Jr. said.

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

"I just want justice to be done," Jones said.

Alayon has hired an attorney who said the officer is cooperating with the investigation. In addition to charges related to the accident, Local 10 has also learned Alayon could face charges of filing a false police report if his car wasn't stolen.
