A DNA sample from a sock cracked a 2013 murder case earlier this month, leading police to the suspected killer of a young man found shot to death in sand dunes outside Ashdod, Lachish region police said Tuesday.The murder of 21-year-old Michael Buskila in November 2013 was originally ruled a suicide, and baffled investigators for nearly two years. Recently, a box was discovered buried in the sand near where Buskila was found, and inside, a pistol that matched the shells that killed Buskila. The pistol was wrapped in a sock inside the box, and on the garment was a DNA sample belonging to Michael Michaelishvili, the 24-year-old cousin of Buskila, who was arrested three weeks ago.Police did not give a motive for the murder.Buskila was found shot to death in the sand dunes outside Ashdod only a few meters from his car. He also had stab wounds on his body. Buskila was found only a few hours after he was reported missing by his parents, and his cousin, the suspected murderer, took part in the search.Lachish region police said Tuesday that on Thursday prosecutors from the southern district will indict Michaelishvili for the murder and will ask he be kept in custody until the end of his trial.
