Following their discovery of bloody clothes in a skip bin, New South Wales police searched Jesse Baird's home in Paddington.
There, cops found a "large amount of blood" and blood-stained furniture.
The amount of blood has led the officers to believe that at least one had suffered "a significant injury".
Upon entering Baird's property, the officers immediately established a crime scene.
Police believe "there has been some sort of incident" after they found blood-covered clothes belonging to Davies and Baird on a Wednesday morning.
At this stage, it is unknown who the blood belongs to.
But a phone, keys and credit cards were also among belongings discovered in the skip bin - 18 miles away from Baird's residency.
