What happened
Werner Ferrari was convicted of abducting and killing children in Switzerland over a period spanning many years.
The investigation
Investigators linked cases through Ferrari’s contacts with victims, witness evidence and renewed examination of earlier disappearances.
What the courts or investigators concluded
He was convicted of multiple murders and received a life sentence, while at least one historical accusation against him was later reconsidered.
Why the case remains significant
The case remains important both for its serial pattern and for the need to distinguish proven convictions from suspicions attached to an offender after arrest.
Case context
Crime by Region organizes cases geographically so readers can move from one file to other investigations from the same country. For unresolved or contested cases, the wording above reflects the distinction between confirmed events, investigative theories and findings actually established in court.
