Identification of a Red-Brown Residue from an Excised Cow Discovered 2-21-2001


Analyze red-brown particles retrieved from the hide near the anal excision of a mutilated cow. It was purported that the event happened “overnight”, i.e. the cow was found in a grove of trees within 24 hours of the event1. Other information indicated there was some rain before the animal was found. The carcass apparently fell through trees because limbs were down and a 6” tree broken. The body contained no blood, an udder was removed, and there was a “hole” in the belly. Scuffed up areas on the hide indicated that the cow was possibly strapped.


The residue found on the excised cow is bovine hemoglobin, a component of blood. This is the second event where hemoglobin has been found2. (The first concerned an excised bull found in Red Bluff, California on 1-17-97.) The presence of hemoglobin would indicate a processing of the whole blood has occurred.

As stated in the report of the first event: “The usual procedure for isolating hemoglobin from whole blood is rather complex. It involves separating red blood corpuscles from the lighter plasma components by centrifugation. The plasma is siphoned off and ether is added to the corpuscle paste, causing the cells to burst. Another centrifugation removes the ruptured cell envelopes, and leaves a clear red solution of hemoglobin.  It is unlikely that a procedure such as this would be done on site. It is unknown how or why this occurred.”
