OLPE, Germany - A 44-year-old woman was arrested on suspicion of killing her own babies after her grown children found the bodies of three infants stashed in the family's freezer while looking for a frozen pizza, police said Monday.

Police confirmed the grisly find Sunday night in the town of Wenden, near Olpe, in the western state of North Rhine-Westphalia after the woman turned herself in, officials said.

The three infants are believed to have been born alive, but authorities were awaiting autopsy results to determine how they died, said Johannes Daheim, a spokesman for prosecutors investigating the case.

The woman, her 47-year-old husband and three adult children - two sons, aged 18 and 22, and a 24-year-old daughter - have lived in the town in a single-family home since 1984.

The children discovered the frozen babies on Saturday afternoon while their parents were away for the weekend, investigator Martin Feldmann said.

The 18-year-old and his sister had been looking for a frozen pizza and came across a lot of expired food so decided to clean out the freezer.

The teenager then found three identical packets on the bottom of the freezer and opened one and saw the head and arm of an infant that was wrapped in a hand towel, police said.
