What are the items on the list?
Synonyms of the words on the list can be anagrammed to a tag on Puzzling SE plus one letter. For example: "Scarlet covers" are "red lids", which is an anagram of "riddle" plus "s". The complete list is:
Scarlet covers: red lids — riddle + s
Swindler's imprecation: con discheat's dammit — coinsmathematics + d (found by JS1)
Sour disordered equipment: acidic unglued tool — logical deduction + u
Smash journal: plow diary — wordplay + i
Sinful America: evil USA — visual + e
Surgeon oath: Dr vow — word + v
Storms carport: typhoons garage — steganography + o
Who is the victim?
If we assume that the third item is correct and that the second item yields an extra d, we can anagram the extra letters to Deusovi. (Thanks, jafe, for spotting that. I had a rather less convincing guess first.)
