50-year-old Joachim Vogel, a German professor, was crushed by a reversing waterbus which bumped into the gondola he was riding with his family on August 17th, near the city's famous Rialto Bridge. His wife, three children and the gondolier were also thrown into the water, with his three-year-old daughter suffering head injuries.
Roberto Terzo, the crown prosecutor leading the investigation, made the video public as authorities continue to examine the causes of the collision. In the video, the crash can be seen in the upper portion of the screen, followed by rescue attempts.
Five people are currently being investigated: three waterbus drivers and two gondoliers, including the driver of the family's gondola, who tested positive for drugs after the incident.
Following the tragedy, new rules were imposed on water traffic, restricting the number of ferries allowed on the Canal and requiring gondolas to improve visibility by fitting number plates and reflectors, as well as tougher drug and alcohol regulation for gondoliers.
