One of the perpetrators will likely be brought to justice, according to Australian police.
"Based on his medical condition, it is likely that this person can be brought to justice," said Mal Lanyon of the Australian Police during a press conference on Monday.
On Sunday evening, local time, two men opened fire at a Jewish festival next to the popular tourist spot Bondi Beach. At least 15 people and one of the perpetrators were killed in the attack. Among those killed was a 10-year-old girl.
Several parallel police investigations are ongoing following the incident.
Father and son
The perpetrators, aged 24 and 50 respectively, are father and son. The 50-year-old man was shot dead by police at the scene while the younger man is being treated in hospital with serious injuries under police guard.
"One of these individuals was known to us, but not from an immediate threat perspective, so we need to investigate what happened," said Mike Burgess, director general of Australian Security Intelligence, according to ABC News .
The son was already being investigated six years ago for his links to a Sydney-based IS cell, according to an intelligence source. The investigation was confirmed by Prime Minister Anthony Albanese, but the son was not considered an urgent threat at the time.
The father has had a gun license since 2015 and several of his six guns are believed to have been used in the attack. He first arrived in Australia on a student visa in 1998 and has held several different types of visas since then, according to Home Affairs Minister Tony Burke. The 24-year-old is an Australian citizen and was born in the country.
Celebrated Hanukkah
Another 40 people were injured in the mass shooting. As of 1 p.m. Monday, local time, 27 people were still being treated in hospitals. Of those, six people, including two police officers, have life-threatening injuries and six others are in serious but stable condition.
A family festival was taking place on the beach to celebrate the Jewish holiday of Hanukkah, with over 1,000 people in attendance. The attack is being investigated as a terrorist attack and was, according to the state premier, targeted Sydney's Jewish population. Police will increase their presence at Jewish sites. Jewish schools and synagogues will remain closed following the attack.
