The search for 25-year-old FIFO worker Bill Carter has taken a chilling turn, with new, unsettling details emerging that suggest his disappearance from Perth Airport on December 6, 2025, may be far stranger—and potentially more sinister—than initially believed. As authorities race against time, conflicting witness accounts, mysterious items found in his luggage, and a cryptic note have sparked a wave of emerging theories online, leaving Perth detectives stumped and the public gripped by speculation. What started as a routine missing person case has morphed into a puzzle that could rewrite everything we thought we knew about Bill’s final hours.
Bill, a slim-built Bunbury local with brown hair and blue eyes, was dropped at Terminal 3 by his mother Jenny O’Byrne at 12:40 p.m. for a 2:15 p.m. flight to Karratha and his Fenner Dunlop mine shift. He texted “love you” at 1:02 p.m., his phone pinged once at 1:05 p.m., then went dead at 1:45 p.m. No boarding scan, no gate sighting. Initial searches focused on the airport, but the discovery of Bill’s backpack washed ashore at Trigg Beach on December 10—30 km north—flipped the timeline. Inside: damp clothes, a wallet with $50, and a handwritten note reading “I need to disappear—sorry,” confirmed as Bill’s script by forensics.
Witnesses complicate the picture. A taxi driver reported picking Bill up at 1:20 p.m., driving him to Trigg Beach—arriving 2:10 p.m.—where a jogger saw him “sitting sad, waiting for someone” at 2:40 p.m. before he walked toward the water. Jenny revealed Bill was “off his anxiety meds” post-Zambia trip, struggling with FIFO isolation. “He said he needed space—I thought burnout,” she wept. The note fuels theories: mental health crisis? Planned vanishing? Or coercion?
Experts are baffled. Retired detective Ken Lang: “The beach detour is bizarre—why Trigg? The note suggests intent, but no preparation.” A faint GPS ping on December 8 in remote bushland 40 km southeast adds urgency. Police warn: “Every hour counts.” A GoFundMe has raised $100,000 for private searches.
As Christmas nears, Jenny pleads: “Bill, come home.” The clues multiply, but answers don’t. Perth waits, unsettled.
