I'm on blood thinners and get nose bleeds all the time. I've left a trail of large drops from the front door through the house to the kitchen. Often my nose starts bleeding and I don't know it. I may realize it when it drips on my shirt, but I don't want to get it on my shirt, so I lean forward to keep my shirt clean. It makes tear drop shapes on my shirt, and when I lean forward, it makes big, round drops on the floor until I can grab a tissue or paper towel. When I go back to clean it up, I've sometimes stepped in it, too. I think she was carried, probably over the perp's shoulder leaving blood drops with nothing to staunch the flow. Also, no footprints in the blood, so again, they (perp and maybe NG) walked there before she bled there. If she was walking, she would have stepped in it, too. He may not have known she was bleeding behind him. Now, if he hit her on the head, I think she would have bled more. Head wounds do generally bleed a lot, and the blood thinners could have increased that flow. OR, if she was already deceased, the blood wouldn't have flowed, but what was there could have dripped. I don't think that's the case because it wouldn't have been a steady drip, drip, drip, with similar sized drops all through the house. Whatever they found inside hasn't been revealed by LE so everything is speculation. Even if she had the nosebleed earlier, t was already dark, so she probably wasn't going outside to clean it then. If she had realized it, she would probably ask the gardener or someone to clean it the next day or two.
