Authorities in Argentina say DNA evidence has linked a 24-year-old Argentine tour guide to the recent murder of two French tourists.

A spokesman from the prosecutor's office in the province of Salta Tuesday said DNA taken from the body of 24-year-old Moumni Houria matches that of suspect Gustavo Lasi. He is one of eight suspects arrested in the case.

Separately, one suspect, Maria Canizares, was found to be in possession of a cell phone and a camera belonging to one of the victims, but Canizares said the items had been given to her by Lasi, her boyfriend.

The remains of Houria and her traveling companion, 29-year-old Cassandra Bouvier, were discovered last month in a tourist area in northern Argentina's Salta province. Both tourists had been shot and authorities say one of the women was sexually assaulted. The two were last seen alive at an area hostel July 16.
