No. But the ridiculously implausible story of seeing one child sprawled out blue (on a black and white monitor), and the other child being strangled by a suddenly distraught wife, causing a man to coincidentally also react by murdering said wife, and to also coincidentally do it via strangling, (not gun, beating with an object, etc.), instead of throwing her off the child and a) Calling 911, b) Checking pulses, c) Immediately attempting to resuscitate one or both children, d) Running out of the house, screaming and wailing for help...that should allow one to make that leap.
Let's add in a couple things that should enable anyone with critical thinking skills to conclude this man's story is nonsensical garbage and he murdered his whole family:
1. After the laughable story of two parents separately and coincidentally reacting with homicide -and not only homicide but coincidentally, the the exact same method - and dad defying all parental instinct and not even trying to rescue the very precious children who he adored so much that he went out of his mind at the sight of someone harming them, after all that, he again fails to call 911 after killing his wife and again fails to scream in agony at what happened and beg, as ALL distraught parents who love their children do, for help that will never come.
In fact, no screaming in anguish is heard from that house at all that morning, despite the incredible proximity of the houses. Wow. That was one quiet event, seeing your precious kids being killed and reacting with unhinged fury. So silent.
He goes from out of his mind with fury and pain to utterly calm, apparently, in an instant.
2. Not only that, he takes those precious children who he loved so much that he killed at the sight of someone harming him, and he loads them up in his truck, calmly drives away from his house and dumps their precious little bodies in vats of dirty, black oil. No burial for them. Not one damn thing about the way their bodies were discarded to indicate they were loved.
3. He goes to work. He killed his "insane" wife because she destroyed the two people who mattered the most to him, right? And he just goes to work. Where he calmly watched the ring video that shows if anyone is coming to the house.
4. This man who simply snapped at the sight of his precious kids being harmed (remember, there is no way he could've known that they were dead or beyond resuscitation from a glimpse in a monitor), he calmly texts his dead wife and leaves voicemails he knows she will never hear, "Where are you, babe?"
5. The man who knows his entire life is floating in dirty vats of black oil, he then calmly calls his wife's friend when he sees her on the ring video at the house. "What's going on?"
6. The same man who after losing his mind from insane anguish, (anguish that was not vocalized at all) quietly loaded his dead loved ones bodies into his truck, dumped their bodies and then calmly went to work, now, NOW, he suddenly shows emotion and with a "racing heart", he runs several stop lights to get home. So scared of getting caught but able to quietly murder your wife, calmly load up your family's bodies, and drive away, dump them and go to work as if nothing happened? Hmm. Does that makes sense?
7. For the next several hours, the father who loved his babies so much that he went out of his mind at the sight of them being harmed and killed for them (instead of trying to do one thing to save them), he calmly goes through all the friend's lists with police, tries every number available and steadily tries to track down his dead wife and rotting children. "I have no inclination as to where they are."
8. Then, this same, passionately adoring father who lost his mind in grief, two days later he grins and giggles and stares clear eyed at several reporters, not one tiny hint of exhaustion, crying, grief, nope. He stands there looking well rested, casually discussing the where abouts of his precious babies who are rotting in oil, and proudly shows of his shirt. A damn shirt. While his kids corpses float in oil.
So a man so passionate he erupts in homicidal fury, and anguish, he can calmly stand on a porch and discuss his dead children two days later? Is that remotely believable folks?
So while we may not be able to make the leap from an affair (which is present in half the family annihilator cases), to murder, it would seem that any rationally-minded human with critical thinking skills and the ability to use basic logic, could make the leap after hearing his ridiculous story and looking at the facts now.
Finally, lying about your murdered family is not the same as giving a job interview at which you're slightly nervous. A person so passionately in love with his kids that he erupts in homicidal fury when they're harmed is not the same man who two days later smirks and giggles with slight "nerves" as he lies about them.
No that kind of man is the kind who wails and screams like women at a Bangladesh funeral, demands that he be put out of his misery, needs to be hospitalized and never, ever tries to hide what happened.
