French police investigating the death of a pregnant woman attacked by dogs while hiking in the forest carried out DNA tests on 67 dogs to try to determine which of the animals bitten, investigators said Thursday.
Elisa Pillarski, 29, was found dead on Saturday in the Rits forest, about 150 kilometers (60 miles) from the Belgian border.
There were dogs on a hunting trip in the forest when she was picnicking.
An autopsy showed that the cause of death was due to bleeding from dog bites in the upper and lower limbs as well as the head.
Soason prosecutor Frederic Tran said the victim was pregnant and contacted her husband, who was at work, to inform him of "dangerous dogs" when she was walking her dog.
According to local newspaper Le Courrier Picard, hunting dogs were hunting deer, but hunting associations denied that their dogs were behind the killing of the young woman.
"There is nothing to suggest that hounds were involved in the death of this woman," the Paris-based French hunting association said in a statement.
