That is a long blood trail. Looks like to me he was shot at the end of the trail, at the edge of the roof, and slid back down it after getting shot.

You are disoriented. He was found by the peak of the roof and the pitch goes down towards the buildings you see here, so he did not slide uphill, but his blood did go downhill.

You're right 🙄 🤦‍♂️. Discussions can get confusing when posted across two threads.
