Galleon Group hedge fund founder Raj Rajaratnam and former New Castle Partner executive Danielle Chiesi, indicted together on criminal charges of insider trading in a slew of tech stocks and set to go to trial in October, want separate trials. Their lawyers claim the case, which includes seven distinct conspiracy allegations, against them is so complicated no jury is going to be able to keep track of what evidence applies to which count and which defendant." Twenty-one people were arrested, 10 have pleaded guilty so far.
