Grimaldi Group is pointing to a Jeep Wrangler as the possible cause of a fire that erupted on a ro-ro vessel in early July off New Jersey that led to the death of two Newark firefighters.

The Grimaldi Deep Sea-operated, 3,950-lane-metre Grande Costa d’Avorio (built 2011) sustained an extensive fire on its upper levels on 5 July while stevedores were finishing loading 1,200 used cars and 157 containers.
