What happened
Four people, including a young child, were killed in an apartment building in Erba in 2006. A fifth victim survived.
The investigation
Investigators focused on neighbors Olindo Romano and Rosa Bazzi, citing confessions, witness evidence and forensic findings. The defendants later recanted and continued to challenge the case.
What the courts or investigators concluded
Both were convicted and sentenced to life imprisonment. Subsequent requests to reopen or revise the convictions have kept the case in public debate.
Why the case remains significant
The Erba case remains controversial in Italian true-crime culture because supporters of the convicted couple continue to dispute the reliability of parts of the prosecution evidence.
