ROME (AP) — It started out as way for grief-struck families to mourn their coronavirus dead online: a Facebook group where relatives who were denied a funeral because of Italy’s stringent lockdowns could share photos, memories and sorrow that their loved ones had died all alone.

But this spontaneous virtual forum for eulogies, anguish and condolences has now turned into an influential activist group that is providing a steady stream of testimony and evidence to prosecutors investigating whether any crimes contributed to Italy’s COVID-19 toll.

Members of the Noi Denunceremo (We Will Denounce) Facebook group and an affiliated non-profit committee filed some 100 new cases Monday with Bergamo prosecutors investigating the outbreak, on top of 50 complaints lodged last month.

Wearing a face mask with the group’s logo outside the tribunal Monday, We Will Denounce co-founder Stefano Fusco said the complaints don’t accuse anyone specifically of wrongdoing.

“We simply tell our stories and ask the prosecutors to investigate about what happened here and why … there was such a huge massacre,” he said.

The case files and Facebook posts paint a visceral portrait of the lives swept up in Italy’s devastating coronavirus outbreak, the first in the West: of mothers and fathers taken away by ambulance and never seen alive again by their children; of frantic efforts to locate vacant intensive care beds and impossible-to-find oxygen tanks; of hospitals so overwhelmed trying to save the living that relatives of the dead were often just an afterthought.

“It’s a system that didn’t hold up, a system that had to choose who to save and who not,” said Diego Federici, 35, who lost his otherwise healthy mother and father to COVID-19 in just four days in March.

Federici believes that neither of his parents was treated adequately. He says his mother was essentially sedated until she died and then her body was transported to Bologna, 250 kilometers (155 miles) away, to be cremated because Bergamo’s crematoriums and cemeteries were full.

“There are too many doubts, too many things that were done badly,” he said in a telephone interview.

Compiled by sons and daughters, widows and widowers, the majority of cases that We Will Denounce has filed with prosecutors concern deaths in northern Lombardy’s provinces of Bergamo and Brescia, where the outbreak erupted in late February. The two provinces fast became ground zero of the European epidemic and together account for around a quarter of Italy’s 35,000 official COVID-19 deaths.

Experts believe the true number of coronavirus deaths is much higher, in Italy and elsewhere, due to testing limitations.

“We are certain that with 35,000 dead, they can’t go and cover up everything as has unfortunately occurred with other Italian tragedies,” said Fusco, who co-founded We Will Denounce with his father after the March 11 death of the family patriarch, Antonio.
