Were Colorado girls strangled? Father’s lawyers requested DNA swabs from children’s necks.

The two young Colorado girls who, along with their mother, were killed this past week may have been strangled before their bodies were dumped in an oil well, according to a court document.
A motion filed Friday by attorneys defending Christopher Watts, who investigators believe killed his pregnant wife and daughters, asks that DNA samples be taken from the children’s necks. The document cites an expert who argued that DNA would still be present on the bodies — even though they had been submerged in crude oil for four days before they were found — but that evidence would be lost once the autopsies were performed.
