A Viennese archaeologist  claims to have found the murdered sister of Cleopatra. The  will speak about how she claims to identify her bones at a lecture in North Carolina.

Cleopatra VII Philopator was the last pharaoh of Ancient Egypt.  It is believed the ruler had her sister, Arsinoe IV killed.

Archaeologist Hike Thur from the Austrian Academy of Sciences explained that a DNA test linked the bones, discovered in an ancient Greek city, but results were inconclusive.

"It didn't bring the results we hoped to find," Thur told the Charlotte News-Observer.

The archaeologist still firmly believes these bones belong to Arsinoe, but the 2,000-year-old bones have been moved around a lot over time.

Arsinoe was Cleopatra's younger half-sister or sister, both of them fathered by Ptolemy XII. When he died, he made Cleopatra and her brother Ptolemy XIII joint rulers.

Ptolemy eventually ousted Cleopatra. Julius Caesar stepped in and took the side of Cleopatra in the fight for power.

During this time, Arsinoe joined the Egyptian army resisting Caesar and the Roman forces.

Arsinoe was held captive as a result of Rome defeating the Egyptians. She was allowed to live in exile in Ephesus, an ancient Greek city in what is now Turkey.

Cleopatra wasn't happy because she saw her sister as a threat to her. Cleopatra would have her murdered in 41 B.C.

In 1904, the bones of a young woman were discovered in Ephesus. Thur believes those bones indeed belonged to Arsinoe.

The bones disappeared during World War II and not found again until 1985 by Thur.

Critics argued that these bones matched someone the age of 15 or 16, which doesn't match Arsinoe.

"This academic questioning is normal," Thur told the News-Observer. "It happens. It's a kind of jealousy."

One other controversy is because the skull had to be reconstructed. This allows this identification to never be certain, even though in 2009, a BBC documentary, "Cleopatra: Portrait of a Killer" backed up Thur's beliefs.

Others disagreed. Candian classicist and teacher David Meadows was one of them.

"We get this skull business and having Arsinoe's ethnicity actually being determined from a reconstructed skull based on measurements taken in the 1920s?" Meadows wrote on his blog rogueclassicism.

Thur will talk more about his theory on March 1 in North Carolina.
