Man began affair before his wife was murdered

SCOTT PETERSON’S one-time mistress Amber Frey testified yesterday that her first blind date with him culminated in a hotel room tryst, revealing the first details of an affair the government says led Peterson to murder his pregnant wife.

Frey, the government’s star witness, held a black bag in front of her face to block the cameras as she was driven to the courthouse, and then spoke so softly on the witness stand that the judge had to ask her to get closer to the microphone.

With short, clipped answers to questions from prosecutor Dave Harris, Frey said she didn’t know Peterson was married that night, November 20, 2002, a little more than a month before Laci Peterson vanished.
