US authorities have charged the 87-year-old driver who allegedly ran a red light at an intersection in Nashville, killing Australian broking leader Tim Wedlock and injuring three others.

Mr Wedlock, who was AEI executive chairman and a former National Insurance Brokers Association president, was on holiday when the incident occurred at 12.30pm, August 1, Nashville time.

Police say Thomas Cahill, of Bowling Green, Kentucky, has been charged with one count of failure to yield resulting in death, and three counts of failure to yield resulting in serious injury.

“The investigation shows that Cahill was travelling south on 4th Avenue North in his Ford Fusion sedan when he came to a stop short of the Broadway intersection,” police said.

“The traffic signal was red for 4th Avenue and pedestrians had the walk signal to cross the street.

“For an unknown reason, Cahill pressed the accelerator, went through the intersection against the red light, and struck the pedestrians.

“Cahill brought the car to a controlled stop on 4th Avenue South and got out of the vehicle under his own power. He was transported to Vanderbilt University Medical Center and was discharged a few days later.

“Cahill has told officers that he has no recollection of what occurred.”

Two of the three injured pedestrians remain in hospital. Nashville media have reported that Cahill’s 90-year-old wife, who was also in the vehicle at the time of the incident, has since died from unrelated causes.

Hundreds of tributes were paid to Mr Wedlock, and about 2000 attended a Sydney service to celebrate his life last month. The Australian and New Zealand Institute of Insurance and Finance also gave him a posthumous lifetime achievement award.
