Going back over my traffic analysis of FBI cell phone calls, I noticed that McGuire was making a lot of calls to 213 894-0336. I already knew that 213 894 was the area code and exchange for the phones at the U.S. Attorney’s Office in Los Angeles. I called the number and found it was the phone for one David Schindler, the Assistant U.S. Attorney who had been the prosecutor on the Poulsen case. He’d be just the guy, I thought, who would get assigned to take on the next big Los Angeles hacker case.
