P.I.: Missing girl stepmom fails polygraph

PALATKA, Fla., Aug. 28 (UPI) -- A private investigator who administered a lie detector test to the stepmother of a missing girl in northern Florida says she failed it.

Tim Miller of Texas EquuSearch said Misty Croslin-Cummings also failed a voice analysis, WFTV in Orlando reported. Miller said Croslin-Cummings approached his firm because she wanted to be cleared of suspicion.

Haleigh Cummings vanished in February while Croslin-Cummings, who had not yet married the little girl's father, was babysitting. Croslin-Cummings claimed Haleigh, then 5, was abducted as she slept in bed.

While Miller, who has turned over his findings to Putnam County authorities, says Croslin-Cummings failed the test "miserably," investigators have described her answers to questions as inconsistent and deceptive.

"You know, we think that Misty needs to tell us some things, fill in some inconsistencies, but that's about as far as we're willing to go with that statement and we'll stop just short of saying, 'Well, therefore we have probable cause to make an arrest.' We don't. If we had probable cause to make an arrest at this point, I think we probably would have," a deputy said.
