"What's the average cost for a lawyer to SUCCESSFULLY try a high-profile murder case?"?

[Morgan R]

well success is relative and dependant on many factors, of course.

but generally, any effort is likely to be MORE successful if more time and effort and resouces are used. That would be generally applicable to all efforts.

But to answer your question, a first rate defense in a homicide SHOULD run over 100K; maybe up to a million depending on how complex the trial is (number of witnesses, forensic evidence and of course that hourly rate)

and that would apply to each side and which is why some jurisdiction decline to ask for the DP or are eager to plea bargain some cases. A couple of homcide trial can bankrupt a small county
