LEE COUNTY, Fla. - Two deputies have been demoted for botching a burglary investigation that lead to a deadly high speed crash.

In July of last year deputies took off after two burglary suspects. As they flew down Palm Beach Boulevard, a car made a U-turn and slammed into an unmarked deputy cruiser. The driver was killed.

Sergeant Kevin Karlsen and Detective William Lucas both lost rank for messing up the original burglary investigation.

An internal affairs report said the two didn't pass along correct information from witnesses to that burglary.
