A man with ties to the British royal family was among the 15 victims killed in the New Orleans attack on January 1.

Edward Pettifer, the stepson of Tiggy Legge-Bourke—former nanny to Prince William and Prince Harry—succumbed to “blunt force injuries” after a truck driven by Shamsud-Din Jabbar, 42, plowed into a crowd on Bourbon Street. The Metropolitan Police confirmed Pettifer’s death in a statement.

Pettifer, 31, was a Chelsea, West London resident visiting Louisiana with a friend, according to reports by British newspapers.

Tiggy Legge-Bourke, now 59, served as a nanny to William, 41, and Harry, 40, from 1993 to 1999, following King Charles and Princess Diana’s separation. She married Edward’s father, former Coldstream Guards officer Charles Pettifer, in 1999.

Tiggy Legge-Bourke shared a close bond with Prince William and Prince Harry during her time as their nanny, a relationship that has thrived over the years. The brothers attended her wedding in 1999, and she was a guest at theirs—William’s in 2011 and Harry’s in 2018. Legge-Bourke is also the godmother of Harry and Meghan Markle’s son, Prince Archie per PEOPLE.

Prince William took to Instagram stories to express his grief.

“Catherine and I have been shocked and saddened by the tragic death of Ed Pettifer.”

“Our thoughts and prayers remain with the Pettifer family and all those innocent people who have been tragically impacted by this horrific attack.”

Edward’s family provided a statement shared by police, “The entire family is devastated at the tragic news of Edward‘s death in New Orleans. He was a wonderful son, brother, grandson, nephew, and a friend to so many.”

“We will all miss him terribly,” they added. “Our thoughts are with the other families who have lost their family members due to this terrible attack. We request that we can grieve the loss of Ed as a family in private. Thank you.” 

Jabbar, who had an ISIS flag displayed on the back of his truck, bypassed a police blockade on Bourbon Street at approximately 3:15 a.m. He then accelerated into crowds of revelers along the iconic stretch, leaving devastation and casualties in his path.

The attack came to an end when Jabbar collided with a crane positioned in the middle of the famous street.

Jabbar exited the truck and opened fire on police officers, who returned fire and fatally shot him.

The attack on New Orleans left 39 others injured. So far, the reported death toll from the deadly New Orleans attack is 15 dead.
