SATSUMA, FL -- Family members, friends and others who know Haleigh Cummings (special report) have been interviewed by investigators, and in many cases, offered lie detector tests.
That includes Haleigh's father, Ronald Cummings and his girlfriend, Misty Croslin, who said she woke up early Tuesday morning and discovered the 5-year-old girl missing.
Cummings said he believes he and Croslin passed the tests. Croslin has been in the spotlight as she was the last person to see Haleigh. "I don't care what people are saying about me because I didn't do it," she told Jacksonville.com.
At a news conference Thursday, Putnam County Sheriff Jeff Hardy confirmed that Croslin had taken a polygraph test, but he wouldn't discuss the results. He did say that all family members have been "extremely cooperative."
Croslin said she woke up at 3 a.m. Tuesday and discovered Haleigh missing and the back door of the home propped open with a brick. Moments later, Ronald Cummings arrived home from work and they both called 911.
The search for Haleigh entered into its third day with the arrival of the Texas-based group Equusearch, which was recently involved in the Caylee Anthony case. Sherriff Hardy said search efforts are being expanded to include aircraft and horseback searches of rough terrain.
Investigators are also looking closely at 44 registered sex offenders who live within a five mile radius of Haleigh's home.
“We’ll expand this investigation as far as it needs to go,” Hardy said.
