The 4-year-old sister of missing toddler Caleigh Harrison may hold clues about her disappearance and is slowly remembering more about what happened on April 19 when her sister vanished.
Lizzie, 4, wasn't talking in the beginning, but her parents said she is now sharing more details of the day she said her 2-year-old sister was abducted.
"At first it was the mean guy and then she got into detail about black shorts, he was smoking a cigarette, he had facial hair," Anthony Harrison, the girls' father, told Nancy Grace.
Lizzie even drew a picture of the man she said took her little sister.
The toddler disappeared on April 19. Caleigh's mother, Allison Hammond, said she was playing ball with her two daughters on the beach in Rockport, Mass. When Hammond returned from chasing after a ball, Caleigh had vanished.
"I looked down and Lizzie had her arms outstretched and she said, 'Caleigh is gone.' She didn't say anything more than that," Hammond said.
State police have searched the beach and said there are no signs of an abduction. Experts also cast doubt on Lizzie's account, which came weeks after frantic searches.
"What happens in children that young is they incorporate comments by people into their own psyche like they're real and so in her mind it may be real. In reality it may not be real at all," said Brad Garrett, a former FBI agent and ABC News consultant.
Lizzie did not mention anything about an abductor during a meeting with a state psychologist, authorities said.
Still, her father is holding out hope Lizzie's memory will help bring Caleigh home.
"This came from her. This came from the heart and I believer her," Anthony Harrison said.
