A coroner's inquiry into the death of 51 Muslim worshippers in 2019 in New Zealand’s deadliest shooting will start on Tuesday, hoping to establish what happened after the attack started and make recommendations to prevent deaths in the future. Armed with high-capacity semi-automatic weapons, Australian Brenton Tarrant, 32, killed 51 people and injured dozens when he opened fire on Muslim worshippers on March 15, 2019, in Christchurch. Tarrant released a racist manifesto shortly before the attack and streamed the shootings live on Facebook.
