May 14 (UPI) -- Buffalo Bills super fan Pancho Billa died on Tuesday. He was 39.
Pancho Billa, also known as Ezra Castro, died following a battle with cancer.
"Our hearts broken as we have lost our dear brother Ezra 'Pancho Billa' this morning," Castro's family tweeted. "We are thankful and forever grateful for all the love and support during this journey. Ezra was surrounded by family and loved ones. At this time we ask for privacy as we mourn our loss."
Bills co-owner Kim Pegula also issued a statement on Castro's death.
"Pancho was a pillar of positive strength and energy for me and all of Bills Mafia," Pegula tweeted. "He's been a tremendous inspiration for our team. I was fortunate enough to spend time with him and get to know his story. My heart goes out to his children, friends and family. Viva Los Bills!"
The Texas native was diagnosed with Metastatic Adenocarcinoma of Biliary-Pancreatic 16 months ago. He continued to attend the previous two NFL Drafts and Bills games after his diagnosis.
