The Dallas Zoo is now saying this week's death of a zebra was an accident.
The six-year-old Hartmann's Mountain Zebra named Keeya was found dead on Monday in the Giants of the Savannah exhibit.
Keeya was the mother of 1-year-old Malawa, who was the first Hartmann’s mountain zebra born at the zoo.
In a tweet, the Zoo invites people to "send your thoughts and condolences to Keeya’s care team and our entire Zoo family as we grieve this sudden, tragic loss."
No one witnessed the incident but the Zoo believes Keeya was injured by another animal.
