A suspect in the mass shootings at two New Zealand mosques on Friday appeared in court on Saturday and was charged with murder. He was identified as Brenton Harrison Tarrant, a 28-year-old Australian, reported CNN. Tarrant, charged with one count of murder, will remain in custody until his next court appearance on April 5. There will likely be additional charges, reported CBC News, but the police have yet to release details of what they may be. At least 49 people were killed in Friday’s attack. The suspect appeared to be a white supremacist motivated by U.S.-based extremism, having posted a manifesto online declaring his hatred for Muslims and idolizing U.S. extremist movements. Christchurch Hospital continued to care for 36 wounded in the shootings, including 11 critically injured. Patients ranged in age from 2 years old to nearly 70, according to David Meates, chief executive of the Canterbury District Health Board. The first victim identified was Daoud Nabi, a 71-year-old grandfather who died trying to save someone else from a bullet, according to his son. At a news conference on Saturday afternoon local time, New Zealand Police Commissioner Mike Bush said authorities would release more information on the victims soon. Of the four people police apprehended on Friday, one was released ― an innocent bystander who “was just trying to get their kids home,” Bush said. Another two individuals are still in custody as the police continue to determine if they were involved in any way.
