The American tourist who was fatally mauled by a lion in Johannesburg, South Africa this week has been identified as Katherine Chappell, a 29-year-old visual effects editor who worked on Game of Thronesand Captain America: The Winter Soldier.

According to CNN, Chappell had traveled to South Africa on a volunteer mission aimed at protecting wildlife.

She was taking photos of a pride of lions while on safari Monday at Lion Park in Gauteng province and had rolled her window down to get a better shot, against the park's rules. As drivers in other vehicles nearby honked their horns to no avail, a lion approached Chappell's vehicle from the side, unseen by her and her driver, and leapt up to bite her through the window, CNN reports.

Chappell's driver attempted to fight the lion off unsuccessfully, and may have suffered a heart attack while doing so, according to CNN. Chappell died at the scene from wounds to her neck.

Authorities are investigating the incident, but representatives from Lion Park have said that the lion will not be euthanized.
