TheTriangle of Sadness actress–– whose full name is Charlbi Dean Kriek ––died from an unexpected and sudden illnessin August. She was 32.

At the time, the illness was not revealed.

A spokesperson for the New York City Office of Chief Medical Examiner confirmed to PEOPLE on Wednesday that she died of bacterial sepsis.

The sepsis “was a complication from asplenia (the absence of a spleen) due to “remote blunt trauma to her torso,” the spokesperson tells PEOPLE.

The South African actress' death was ruled an accident.

Her bacterial sepsis was caused after she was infected with a bacteria known as Capnocytophaga. While the infection is rare, there are different species of Capnocytophaga that develop in the mouths of humans and which are also present in the mouths of dogs and cats,according to theCDC. People with autoimmune issues and without spleens are particularly susceptible.

It is not clear if an animal bite or lick was responsible for the model’s infections as the medical examiner has not made her full autopsy public.

Days after she died, Dean’s brother Alex Jacobs toldRolling Stonethather sudden deathin New York City on Monday happened aftershe began experiencing “minor” symptomsand soon asked her fiancé,Luke Volker, to take her to an emergency room. She died just hours later.

“This happened literally within the span of a day: getting a headache, going to sleep, waking up her boyfriend and saying please take me to the hospital,” Jacobs toldRolling Stone.

“We still aren’t entirely sure [what happened],” Jacobs added at the time. “There’s an autopsy being done which we know might take quite a while. But what we have heard [that] there was a viral infection in her lungs.”

Jacobs toldRolling Stonethat Dean was involved in a “very, very bad car accident” around 2009, after which doctors removed her spleen. She also suffered broken ribs and a broken back in the accident, according to her brother.

“[The spleen is] involved in fighting off infections, and that could have had something to do with what happened,” Jacobs said. “Her spleen not being there just added on to the reason why she perhaps couldn’t fight it off.”
