That carried over into their last conversation, he said. She left their home Sunday morning to help a relative paint, then called him at their home at about 9 p.m. Sunday.
"She seemed snotty," Peterson said, describing the call as "unusual" though he wouldn't disclose details of what was said.
That call at 9 p.m. Sunday was his last communication with his wife -- and even then he said he didn't know where she was calling from.
"I don't know where she was when she called," he said.

Peterson, a 29-year veteran of the Bolingbrook Police Department, said he doesn't know why his wife of four years would leave him and their two children, ages 2 and 4, behind. She also adopted his children from a previous marriage, he said.
"I find that very unusual," he said of her absence. "She's a very good mom. For the last year or so, she's been very short-tempered, snapping on everyone, but still a good mom."

He said he thought their marriage was solid.
"I believed our marriage was good, but maybe she didn't," he said.
He believes the publicity surrounding her disappearance may prompt her to return, but added cryptically," there's other things involved."
Now taking leave from his job -- which he was set to retire from on Dec. 16 -- Peterson said he talked "for a while" on Monday night to state police investigators searching for his wife.
He said he found her purse, cell phone and even some clothing gone after she left their two-story brick home on Sunday.
