Unsolved Mysteries Episode 2 of Vol. 4: A weekend away, a life forever changed

Let's rewind to October 26, 2015. Lee Antoni returns home to Calgary after a weekend in Saskatchewan helping his mom. Totally normal. What's not normal? He found his wife, Amanda Antoni, dead in their basement. Lee tells Unsolved Mysteries:

“Amanda never really liked the basement that much...She just had a creepy kind of feeling about the basement.”

The scene was straight-up horrifying. Sgt. Trent Petersen, who responded to the 922 call, says:

“This was the bloodiest scene I’d ever walked in on.”

According to Lee, their last conversation was Saturday, evening. Amanda mentioned her migraines were finally easing up, and then, in a chilling twist, their dog Ruby began barking. Amanda tried to calm her, Lee heard a strange crunching sound...and the phone line cut out. No callbacks. No texts. Radio silence.

Amanda stayed behind that weekend due to her migraines. But something about her final moments fell off. Even neighbors heard yelling and a loud bang around the same time Lee was on the phone with her.

One person even claimed to see someone sprinting from the area. Now, this episode of Netflix's Unsolved Mysteries gets even weirder. There were no signs of forced entry. So, if someone was inside, they either had a key or knew how to slip in without a trace.

Accidental fall… or foul play?

So, what does Unsolved Mysteries think happened? Depends on who you ask, really. The autopsy revealed Amanda died from blunt force trauma, something that is not uncommon in falls, but suspicious when combined with the broken piggy bank fragments embedded in her...forehead?

And get this — her bloody footprints were found at the base of the stairs, suggesting she got up and moved after falling. Yet she never climbed back up. Why?

One family member insists in the episode, saying:

“There was more to it...The dog was barking. There was a chair overturned in the room. I just don’t believe it was an accident. Somebody pushed her down the stairs.”

The dog angle really throws things into Unsolved Mysteries mode. Ruby, their black Lab, didn't go down into the basement to check on Amanda for nearly two whole days. That's odd for a dog known to comfort its humans when something feels off.

One investigator even wonders out loud by thinking:

“Was there somebody in the house to prevent the dog from going downstairs?”

And about that ceramic piggy bank? It had been smashed near the body. It could have been the murder weapon. Or maybe Amanda fell and hit her head on it. Experts could not even agree, and ultimately, the medical examiner ruled the cause of death "undetermined." No suspects, no arrests. Just one very big, messy jigsaw puzzle.

The haunting aftermath and lingering questions

Despite being cleared early on, Lee Antoni knew suspicion would land on him. that's just standard operating procedure when a spouse dies under mysterious circumstances. But he had a hard-rock-solid alibi.

Surveillance footage, receipts, you name it. All confirming his whereabouts, hundreds of miles away. So, if not Lee...then who?

As Unsolved Mysteries lays out, Amanda's death is officially still "undetermined":

“There are still unanswered questions in this case. Factors that I can’t explain. Things that just don’t make any sense at all,” Calgary police admit.

It is basically Unsolved Mysteries' mission statement at this point.

Amanda's family hasn't given up hope. They believe someone out there knows something. And with the case featured on a show known for stirring up long-buried secrets, maybe, just maybe, new answers will emerge.
