Willy Joseph Cancel, 22, was killed Monday while working for a military company that sent him to Ukraine, his mother, Rebecca Cabrera, told CNN. Cabrera said her son was working as a penitentiary in Tennessee and had registered to work with a private military contractor shortly before the fighting in Ukraine began in late February. He told CNN he had agreed to go to Ukraine. “He wanted to go because he believed in what Ukraine was fighting for and he wanted to be a part of it to limit it there so that he would not come here, and that maybe our American soldiers should not be involved in that,” he said. Cabrera said her son’s body was not found. “They did not find his body,” he said. “The men who were with him are trying to grab his body or kill him, but we would like him to come back to us.” She said her son flew to Poland on March 12 and shortly afterwards entered Ukraine, where he fought alongside men from various countries. The United States has not confirmed the reports. On Friday, the State Department said it was aware of the reports and was “closely monitoring the situation.” For privacy reasons, we have no further comments.
