The man found dead beside State Road 29 in Immokalee has been named as Landin Ahrens, 19, and the Highway Patrol now believes he was struck on Friday night, close to three days before a passing driver spotted his bicycle

The man who was found dead beside State Road 29 near Immokalee on Monday has been named, and the Florida Highway Patrol now believes he was struck days earlier than the day he was discovered.

Gulf Coast News reports, from the Highway Patrol, that the bicyclist killed in the hit-and-run was Landin Ahrens, 19, and that his family is asking for help finding the driver responsible.

The station reports that on Monday a driver traveling along State Road 29 and State Road 82 noticed a bicycle on the grass shoulder and contacted law enforcement.

Lt. Gregory Bueno of the Florida Highway Patrol told the station what troopers found when they got there.

"Florida Highway Patrol responded to the scene, and indeed, we located a deceased young male, and there was a bicycle in the area as well."

Investigators are now working to determine whether Ahrens was struck and killed days before he was found. Bueno put the working window this way to Gulf Coast News.

"What we're able to determine at this point, looking at the totality of everything, is this incident probably occurred several days before in the form of a hit-and-run traffic crash. And we're kind of trying to narrow a window as best we can, and we're looking at this time, Friday evening around 10 or 11 p.m."

That is the agency's estimate rather than a determined time of death, but if it holds it places the crash close to three days before the bicycle was spotted.

A family member told the station there is a reward for any information that leads to an arrest. No amount was given.

Bueno said investigators are searching for a vehicle with a busted headlight, which is the same description the Highway Patrol gave when it first reported the death. No vehicle has been recovered, no driver has been identified, and nobody has been arrested or accused.

Anyone with information is asked to contact the Florida Highway Patrol or SWFL Crime Stoppers, which takes tips anonymously.

There is no document behind this one. The Highway Patrol has issued no written release on the identification or the revised crash window, and its newsroom pages return nothing, so the agency's account here reaches the public through its spokesman in a television interview and is credited that way.

This desk reported the death on August 18, when the man had not been identified publicly and the Highway Patrol said the date and time of the collision were still under investigation.
