The mother of missing Maine toddler Ayla Reynolds said she will take a polygraph test and make the results public.

"I have been offering to take a polygraph test since day one," Trista Reynolds, 23, told the Bangor Daily News on Monday, almost a month after the 21-month-old girl's disappearance.

"When I go, you best believe I'm going to tell everyone out there the results."

The announcement comes just days after Ayla's father, 24-year-old Justin DiPietro, said he had taken a polygraph test. The results have not been released publicly.

Though DiPietro told the Morning Sentinel on Jan. 13 he was "never allowed to see" the results of the test, Maine Department of Public Safety spokesman Steve McCausland said DiPietro "knows how he did, because we told him."

In the interview at her home in Portland, Maine, Reynolds said she has become increasingly suspicious of DiPietro, especially as he has not communicated with her over the past week.

DiPietro maintains he had nothing to do with his daughter's disappearance.

He reported Ayla missing from his home in Waterville, Maine, on Dec. 17. She was last seen asleep at the home the night before.

Reynolds said that she filed for full custody of Ayla just a day before her daughter went missing.
Waterville Police announced in late December the case had "evolved from the search for a missing child to a criminal investigation."

A $30,000 reward is being offered for information leading to the safe return of the girl.
