Authorities found remnants of a wetsuit and a surfboard with “one bite in the middle” after locals reported a shark attack
A school teacher is believed dead after being attacked by a shark in South Australia.
Simon Baccanello, 46, is "presumed dead" after going missing at remote Walkers Rock Beach, around 450 miles west of Adelaide.
A witness at the scene, Jaiden Millar, was surfing near Baccanello when the attack happened, reported CBS News.
"I saw his board tombstoning, which means he's underwater and his board's getting dragged under ... trying to fight his way back to the surface," Millar said, per CBS News.
On Monday, South Australian police said that emergency services located "two items of interest" in relation to Baccanello's disappearance on Sunday.
They added that Baccanello was "presumed dead after a shark attack."
"One item appears to be a piece of wetsuit material, and the other items appear to be small pieces of white polystyrene (possible surfboard material). No other items have been located to date," the release continued. "Police will send the found items to be forensically analysed."
"In consultation with the family, Police will continue to search Walkers Rock and surrounding beaches in the coming days after high tide," the police continued.
Local State Emergency Service manager Trevlyn Smith told News Corp that the surfboard remnants had "one bite in the middle," reported CBS News.
Speaking to CNN, the principal at Baccanello's school described the teacher as having "a real keenness with his students to make them feel good."
The attack comes just two months after a teenage girl was killed in a rare shark attack in Western Australia.

"There was possibly a pod of dolphins seen nearby and the young female jumped in the water to swim nearby the dolphins," Police Acting Inspector Paul Robinson said per the AP.
Authorities were called to the scene just before 4 p.m. near a traffic bridge, where Berry was pulled from the water with critical injuries, including massive blood loss, 7 News Australia reported.
Tragically, the girl died at the scene, according to The Sydney Morning Herald. It was the first fatal shark attack on the river in 100 years.
"The family weren't there when this took place, however, her friends were and as you can imagine this is an extremely traumatic incident for anyone to witness," Police Acting Inspector Paul Robinson said, per CBS News. "So obviously we're offering counseling services to anyone who did witness it or is affected by the incident."
