By: Meredith McCown TULSA, Oklahoma - Oklahoma Game wardens say they now know what caused the deaths of seven geese on Tulsa's 11th Street bridge. Game wardens said at first it looked suspicious, since the geese were lined up along the road and looked like they could have been killed on purpose. But after posting to social media, people who were there called and said the birds were run over. A warning, some of the images in the video may be disturbing. Game wardens found out 25 geese were trying to cross the road Sunday night at the Route 66 Bridge. Police and firefighters were even blocking the road to help them, but seven were hit. That's why they moved them to the side of the road.
