by Robert Riggs This isn’t the kind of story I usually tell. The police didn’t converge on the scene with sirens blaring and guns drawn. But what happened inside a Dallas apartment complex was just as devastating and just as unforgivable as a cold-blooded murder. In 2015, a silent killer slipped into the home of two young children. Not through malice, but through neglect, greed, and a rusted furnace exhaust pipe no one wanted to fix.  The carbon monoxide gas that leaked out of it took their minds, leaving them permanently brain-damaged, trapped in silence. For nine years, their mother fought a legal battle against apartment owners and their insurance company, which denied everything.  What followed was a story of delay, deception, and courtroom drama that will outrage even the most hardened true crime listener. This episode is a departure from my usual reporting, but it’s one I had to tell.  Because sometimes, the deadliest crimes aren’t committed with a weapon.  They’re committed with indifference.
