Forgetting to pick up the casings he left behind, which helped police narrow it down to a fellow police officer.

That, and his ex said he was being stalked by said police officer. Idk how he thought he’d get away with it.

I’m also going to assume he won’t spill where he dumped their bodies, as an extra ‘fuck you’ to their families.

Also doesn’t surprise me that it’s a NSW police officer. They haven’t exactly got a good name for themselves
