A Florida zookeeper who was fatally attacked by a tiger in April had screamed for help into her radio before she was killed, according to an autopsy report released on Friday.

Stacey Konwiser, 38, died of a fractured spine and lacerated jugular when she was attacked by a 350-pound Malayan tiger before her co-workers could reach her, the Associated Press reported, citing the report from a medical examiner.

Konwiser had entered the “night house,” where the tigers eat and sleep, and her view of the animal might have been limited, the AP reported. The tiger’s cage was open, though it was supposed to be locked.

Konwiser was the lead tiger keeper at the Palm Beach Zoo, where she had worked for three years.

Investigations into the incident by the Florida Fish and Wildlife Conservation Commission and the Occupational Safety and Health Administration are still ongoing.
