CHARLOTTE -- The brother of murdered UNC Charlotte student Irina Yarmolenko says someone has recently vandalized her gravesite. Pavel Yarmolenko says flowers planted at his sister’s grave in Chapel Hill were dug up.

The UNCC student was found dead along the banks of the Catawba River around the first of May. Her death is still being investigated as a homicide, after the cause of death was determined to be asphyxiation.

No arrests have been made, and a $15,000 reward is being offered for any information which leads to the arrest and the conviction of the person or persons responsible.
