In a plot twist right out of a TV Police Science drama, French Cops in the southern city of Marseilles have narrowed the field of suspects in a series of rapes to two men:  Identical Twins.

Six women were attacked between September of last year and January.  And the DNA evidence points to 24-year old twin suspects are identified only Elwin and Yohan.  Both men deny involvement and are being held without bail. 

Testing to tell the difference between the twins' DNA extremely difficult and expensive:  As much as $A1.3 MILLION, which is a might beyond the means of this city for now.  But without those tests, investigators say it will be tough to figure out which man is responsible, or if both men are serial rapists.  The victims can identify the men, but can’t tell them apart.
