Peterson's Friends: Puzzled and Sad

M O D E S T O, Calif., April 23 -- Kristen and Greg Reed looked forward to sharing play dates and birthday parties with the Petersons, but now they're struggling with grief and confusion over the friends they thought they knew.

Greg Reed met Scott Peterson about a year ago through the Rotary Club. The two men became friends, and would talk a few times a week and periodically meet for drinks. Kristen Reed and Laci Peterson, who were both pregnant, developed a friendship through their husbands.

Reed said he never saw anything that would indicate the Petersons were having any kind of marital trouble, and he said Scott never mentioned his affair with Amber Frey, a single mom from Fresno.

"They were fun to be around," Greg Reed said on ABCNEWS' Good Morning America.

"They both seemed extremely excited, as we were. We were both having our first babies at the same time or quite close to the same time. We were both planning on basically raising them together since we both lived here in Modesto and in the same neighborhood," Reed said.

Now Kristen, whose due date was a few weeks ahead of Laci's, is the mother of a son named Connor, the same name Laci had chosen for her unborn son.

The Reeds say they're not sure what to think of Scott Peterson's arrest last week. Greg Reed said he last spoke to Scott on Christmas Eve, hours before Laci was reported missing. Reed said Scott called him from his cell phone to firm up New Year's Eve plans they had.

"On the afternoon he called from his mobile phone to mine, and we had spoke probably once or twice a week, so it wasn't a phone call that I would see as unordinary. He sounded chipper and looking forward to getting together," Reed said.

Reed said Scott never mentioned that he had been fishing that day, but he said he didn't find it unusual since it was a short conversation.

Later that day, the Reeds heard from Scott again, but his demeanor had changed.

"It went from a wonderful celebration of Christmas to a frantic voice mail message from Scott that evening looking for Laci, wondering if I had talked to her that morning," Kristen said.
