The Watchtower Victims Memorial is dedicated to the memory of Jehovah's Witnesses and their minor children who died as a result of the Brooklyn-based Watchtower Bible and Tract Society's decrees banning blood transfusions, organ transplants, skin grafts, and vaccinations -- as well as other individuals whose deaths due to suicide, abandonment, etc., are attributable to the Watchtower Society in the view of surviving loved ones.
More about Marcos Alegre Vallés
from "Jehovah's Witnesses and Blood Transfusions in Spain" by Dennis Swick:
"1994 Zaragoza, Spain: 13-year-old Marcos Alegre Vallés had leukemia and needed a blood transfusion. His parents were Jehovah's Witnesses and refused to allow the doctors to give him the necessary treatments. A court order had to be acquired to give the needed blood but by the time it was administered it was too late. He died shortly after it was given. (El Mundo, Sept. 17, 1994)"
