On a recording of the second call obtained by ABC News, Adam Baker said that the last time he saw his daughter was at 2:30 that Saturday morning. But two days later on "Good Morning America," Adam Baker said that because of his work schedule, he hadn't seen the girl since Thursday. The girl's stepmother, Elisa Baker, was the last one to see her alive at 2:30 a.m. on Saturday, Adam Baker said.
Adam Baker has said that it is possible Elisa Baker was involved in his daughter's disappearance.
Baker can be heard on the call describing how the police had been out to his house the night before on a seemingly different case.
"The police were out here last night after finding a ransom note for my boss's daughter. I got up a little while ago and it appears they took my daughter instead of my boss's daughter," he told the 911 operator, saying that he last saw his daughter around 2:30 a.m. that night.

"I don't know if they set a fire in the yard to distract us to go out and then they snuck in the door, or, I don't know," he continued. "Somebody had put gas in my company's truck that I drive for work. They left the ransom note on the company vehicle to my boss saying they had his daughter and his son was next."
It was that ransom note that Elisa Baker admitted to writing, in order to throw off the investigation, police said.
Later in the call, Baker chuckles with the dispatcher after he described his daughter's disappearance.
"My daughter's coming into puberty so she's in that brooding stage, so we only see her when she comes out, when she wants something," he said.
Through her court-appointed attorney, Baker continues to deny she had anything to do with Zahra's disappearance.
Authorities confirmed over the weekend that the missing girl was last seen alive on Sept. 25. On that day, the girl and her stepmother visited a Hickory furniture store, said the store's manager, Pat Adams. The Associated Press reported Adams said she went to police after seeing the girl's picture on the news and recalling the visit.
A MySpace page apparently run by Elisa Baker under the username "gothicfairy6668" was covered in gothic images including a skull and crossbones background, before it was taken down. The page, first reported last week by WBTV, features a slideshow of what appear to be personal photographs, including several pictures of the missing girl. The caption of one image of Zahra reads, "The Dark Child!!!lol"
Much of the biographical information on the page coincides with that of Elisa Baker, from the user's age of 42, her husband's name Adam, as well as photos of her husband and Zahra.
The last time the user logged on was Oct. 8, the day before Zahra was reported missing. In the "Details" section of the page, the user wrote that she's a "proud parent." Under "Mood," she wrote "crazy."
While executing search warrants for the Bakers' two cars and home, police recovered possible blood samples, samples of the materials burned in the fire as well as drug paraphernalia.
Police are looking into claims by a relative and former neighbors that Zahra was physically abused by her stepmother before she vanished.
A photograph of missing 10-year-old Zahra Baker with a bruise under her eye surfaced last week in which the girl has what family friend Brandy Stapleton called a visible bruise under her eye.
