LAFAYETTE - State police are investigating a fatal crash in which a Lafayette Parish sheriff's patrol car hit and killed a man who was standing in a road late at night.

Master Trooper Brooks David said Saturday that the crash killed 34-year-old Grant Hamilton of Lafayette.

He says Hamilton was standing in the eastbound lane of Louisiana Highway 98 when Deputy John Malveaux was driving his fully marked car down the highway for a non-emergency call about 11:45 p.m. Friday.

David says Hamilton died shortly after arrival at a hospital.

He says Malveaux submitted to a breath test, which did not show any sign of alcohol. David says Hamilton's blood will be tested at the state police crime lab.
