(CBS/AP) WATERVILLE, Maine - The father of missing Maine toddler Ayla Reynolds took a polygraph test after she disappeared from his home last month, police say.
According to CNN, police would not reveal when the test was given to Justin DiPetro or what questions he was asked, and neither DiPietro nor police revealed the results of the test.
DiPietro, who reported his daughter missing from his Waterville home Dec. 17., told the Portland Press Herald he doesn't know how he did on the test. Police say they told him the results.
"He knows how he did, because we told him," Steve McCausland, spokesman for the state Department of Public Safety, told the Herald. "To say that he didn't know is just not true."
Earlier this week, divers searched a half-mile stretch of an icy river without finding any sign of the toddler, who was wearing pajamas with the words " Daddy's Princess" on them and had a cast on her broken left arm before she vanished.
Authorities say they're continuing to investigate hundreds of leads from around the country.
Ayla was 20-months-old at the time of her disappearance.
