It depends.  According to pro-cooked and pro-raw diet claims,  it seems that toxins can accumulate both in the organs and in the fat, depending on the type of toxin:-

The rawist claim is usually that raw  animal fat can somehow "bind" with the toxins thus neutralising them to some extent, and lessening any impact  on health. I have yet to see any evidence for that, and am highly sceptical of such a notion, given my own negative experience with raw, grainfed fats. 

Judging from the various raw and cooked palaeo forums, rawpalaeos seem to be usually  more interested in whether their meats come from a high-quality source(ie grassfed/wild etc.) or not, than cooked-dieters. While there is a concern for health involved, a large part of the reason is also that most Rawpalaeos find the taste of  raw, grainfed  meats and similiar raw meats from intensively-farmed animals to taste absolutely disgusting. By contrast, the taste of raw, grassfed meats and raw wild game is considerably easier for them to get used to and, ultimately,  enjoy.

Is it not true that most of the toxins of feed or environment are stored in an animal's fat, and that we have to be rather choosy about the sources of our dietary sources of animal fat, whether cooked or raw?  

It seems a lot of primal diet aficionados use meat from a huge variety of modern sources and to me that's questionable.
