Ohio ? A newborn girl was found in a basket on a doorstep 45 miles from where a pregnant woman vanished, authorities said Tuesday.

A DNA sample was taken from the infant and given to authorities investigating the disappearance.

Thomas Maurer, sheriff in neighboring Wayne County, said a doctor determined that the baby was less than 24 hours old. He said he didn’t believe the baby was related to the missing woman, Jessie Davis, of North Canton, but that officials were using “every caution we can” to eliminate that possibility.

Davis, 26, who is due July 3 with a baby she planned to name Chloe, has not been heard from since Wednesday evening when she spoke to her mother by phone.

A couple discovered the newborn on the porch of their rural home south of Wooster on Monday night, Maurer said. The baby was dressed in a sleeper. The wicker basket contained a blanket and a bottle of formula, but there was no note, he said.

Don Redman speculated the baby was left by someone who knew his wife’s background as a nurse at a local free clinic.
