An American citizen and Marine veteran Willy Joseph Cancel has died fighting alongside Ukrainian forces in Ukraine, the man’s widow confirmed to Fox News Digital early Friday morning. “My husband died in Ukraine,” Brittany Cancel, the widow of a 22-year-old veteran marine, told Fox News Digital. “He went there wanting to help people, he always felt that this was his main mission in life.” RUSSIA INVASES UKRAINE: LIVE UPDATES Cancel leaves behind his wife and a 7-month-old son.

All I want is for him to return home and give him the proper burial he deserves.” The Marine veteran enrolled to work for a private military contractor company in addition to his full-time job as a penitentiary shortly before the war broke out in Ukraine in late February, Willy Cancel’s mother Rebecca Cabrera told CNN. After the start of the war, the company asked contractors to fight in Ukraine and Cancel agreed to go, the mother said. Cabrera did not respond to a request for comment from Fox News.

Of course, when he learned about what was happening in Ukraine, he wanted to volunteer.” Willy and Brittany Cancel at their wedding.
