The list of demands specify delivery of four different payments to various people. And the people are named! However, I cannot assume that these are the responsible parties -- they may be red herrings. Fingerprint and DNA analysis are as yet inconclusive.
Until proven guilty, I have blocked out the names from the accompanying photograph and this copy of their list:
1 flower to Mrs. ______
1 Heart record to Ms. ______
1 vegan friendly snack to Mr. _____
1 MP3 to Mr. _____ to his liking
all demands must be met by end of day friday. do not force us to take action by failing to comply
