Mileydis Aldana, whom the internet dubbed “Owl Killer” after she posted the gruesome clip, was killed Sunday when a pair of men on motorcycles opened fire outside her home in Corozal.
Aldana was leaving her home when the incident occurred.
She was rushed to a local hospital by family members who heard the shots but was pronounced dead on arrival.
She was questioned by police in June after they were made aware of a video showing Aldana decapitating a white barn owl, but she was not charged, the outlet reported.
Police have released no motive for the slaying, though Aldana had reportedly received several death threats on social media relating to the incident.
