LAPLACE — A LaPlace motorcyclist was killed Sunday afternoon, authorities said, the result of a two-vehicle crash along Airline Highway in St. John the Baptist Parish.

The crash took the life of 47-year-old Clifton Campbell of LaPlace, according to Louisiana State Police.

The initial investigation indicates Campbell was riding a 2014 Yamaha motorcycle northbound on Airline Highway shortly before 4:30 p.m.

At the same time, 58-year-old Rodney Keller of Reserve was traveling southbound in a 2002 Ford F-150.

For reasons still under investigation, State Police said, Keller turned left at the intersection of Cambridge Drive into the path of Campbell’s motorcycle. As a result, the motorcycle struck the pickup, ejecting Campbell.

Despite the fact that he was wearing a DOT-approved helmet, Campbell was pronounced deceased on scene by the St. John Parish Coroner’s Office.

Impairment on his part is unknown at this time, but a toxicology sample will be submitted to the Louisiana State Police Crime Lab for analysis.

Impairment on the part of Keller is not suspected.

Louisiana State Police said the crash remains under investigation.
