The son of former HarperCollins executive Greg Giangrande died in a horrible motorcycle accident in Thailand this week, the Daily Mail reported. A family spokesperson said Elias Giangrande, 28, and his friend Jack Niehaus, 25, were killed while “on the side of the road attempting to repair the motorcycle.” The two men had attended a Full Moon Party and were reportedly headed back to their hotel when the tragedy struck around 4:30 a.m. on April 24. Both of them were pronounced dead at the scene. The taxi driver was not injured. Koh Phangan Police Lieutenant Suteep Chadakan said that blood alcohol test results were still pending from the hospital. “Officials have coordinated for the family to come pick up the bodies,” he added.
