I sent a lightly armed team to investigate the sightings of this strange creature. Unfortunately, another team had to be deployed to retrieve the corpses of the first team, which had been dismembered by something extremely sharp. There were also multiple stab wounds that appeared to be made by a giant spear.
Trace amounts of a peculiar chemical substance were detected on the eyes of some of the corpses. What kind of mutant organism we are dealing with is still unknown at this time.

According to the initial investigation, we could be dealing with a new type of B.O.W. Based on the creature's style of attack, I have codenamed it "Reaper" for the time being.
Of course, more data on this creature is still required before a thorough analysis can be submitted.
