LONGMONT, Colo. — A woman advertising baby clothes on Craigslist lured a pregnant stranger to her Colorado home and then stabbed her in the belly and took out her unborn child, police say.

Dynel Lane, 34, told her husband when he returned home Wednesday that she had suffered a miscarriage, and he rushed her to a hospital with the baby, police said. The child did not survive.

The 26-year-old expectant mother, who was seven months pregnant, was found beaten and stabbed at the suspect's home, Longmont police Cmdr. Jeff Satur said. She had undergone surgery, and on Thursday was alert and answering questions, police said.

The mother went to the house in response to the online ad and "when she got into the house, she was attacked, she was beaten, and her baby was removed or cut out of her," Satur said. Lane had already left the house when police arrived.

Lane, a mother of two, and the pregnant woman, who was not identified, did not know each other, investigators said. Police are looking for any other mothers who may have responded to Lane's ad for baby clothes.

Lane was arrested at the hospital on suspicion of attempted first-degree murder, first-degree assault and child abuse knowingly and recklessly resulting in death.

Boulder County District Attorney Stan Garnett said his office will consider what formal charges to file.

"The issues involving an unborn child are complicated under Colorado law," he told the Longmont Times-Call. "In most circumstances, if a child was not actually born alive, then homicide charges are not possible."
