What happened
Hamdi Kayapınar was linked to a series of murders and robberies in and around Kayseri over many years.
The investigation
His criminal history included an early family killing followed by later attacks on people he encountered or selected for robbery. Renewed offending after imprisonment brought him back into police custody.
What the courts or investigators concluded
Courts convicted him of multiple murders and imposed aggravated life sentences.
Why the case remains significant
The case is particularly troubling because serious violence recurred over a long period, creating questions about risk assessment and the supervision of offenders released after earlier crimes.
