Conspiracy in Looking for Life on Mars?

NASA has identified Martian meteorites for a long time (note 1), but no scientist in the whole world has tried to look for animal fossil cells and tissues in Martian/non-Martian meteorites. Why? No conspiracy?

In 1996, David McKay found “bacteria” fossil in Martian meteorite ALH84001 (note 2). Since then no scientists tried to find animal cellular fossils in Martian meteorites, although cyanobacteria and diatom fossils have been found in “non-Martian” meteorites (note 3). In 1970 scientists found amino acids in Murchison meteorite (notes 4, 5). Since then no scientists found amino acids in Martian meteorites until two months ago (6). Why did it take scientists over 40 years to find amino acids in Martian meteorites? 

One year ago scientists found macromolecular carbons in 10 out of 11 Martian meteorites (note 7). However, up to this date no scientist has tried to find animal fossil cells or tissues in Martian meteorites. If they had tried, they (animal biologists) should have had no problem in identifying past animal cells and tissues in Martian meteorites, as such fossils are all over Martian meteorites (note 8).

So, is there no conspiracy in Moon Landing (note 9), Mars Sample Return Mission (note 10) and trying not to find life on Mars (note 11)?
