My neighbor Karen killed my dog!😭

Keep in mind that these stories are not real.

My neighbor (who we will call Karen) has made several complaints about my dog, Kera, continuously peeing on her flower. I decide to trust her and check out shared fence for any holes. I didn't see any holes so I decided maybe she dug a hole in the ground. I check the whole backyard and didn't see any holes in the ground. I then go into the house and by several cameras to see if Kera found a different way to Karen's backyard. The cameras come in the next day so I set them up. After a few more days , Karen complains to me again the Kera was peeing on her flowers. Because of this I go check the cameras to find nothing. This cycle continues as she gets even more mad after every accident. Eventually I let Kera outside and after 30 minutes, I decide that it is time to bring Kera inside. I call her about 6 or 7 times and nothing. I decided to check to cameras to see Karen deleting Kera.
