MIAMI -- The family of a man killed Oct. 10 in a hit-and-run wreck is looking for answers about how he died -- and how a Miami police officer's car was involved in the crash.

According to the Florida Highway Patrol, Ryland Nye, of Pompano Beach, was rear-ended as he drove west on Interstate 595 near Flamingo Road. Nye's vehicle hit a guardrail and flipped over, ejecting Nye. He was killed instantly when two other vehicles ran over him. Several other vehicles were involved in the wreck, but no one else was seriously injured.

The driver of the Lexus that hit Nye's vehicle took off on foot, FHP said. Court records show that the Lexus is registered to Miami-Dade 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. The investigating officers said that they noted that Alayon smelled of alcohol and that he had bruises and cuts on his knee.

Police said because there were no witnesses who could identify the driver of the Lexus, they are continuing to investigate. Alayon provided investigators with a DNA sample. Detectives said that they are checking to see if the DNA matches blood left in the Lexus by the injured driver.

Nye was buried Oct. 15 at Forest Lawn North Cemetery.

Miami-Dade police have launched an internal investigation into the incident.
