POLICE believe a 72-year-old insurance claims adjuster arrested last month is the most prolific serial killer in the city’s history, having raped and strangled as many as 30 older women over two decades.

POLICE hope a $500,000 (€350,000) reward will help them catch a serial killer who has claimed the lives of at least 10 women and a man in a two-part string of violence spanning more than two decades.
