I suspect the article I copied from and pasted was from 1988. My point was that there are poisons that can mimic a heart attack. That may be the case here as well.
A teenage girl killed off her father with a fake heart attack in Dallas.
She’d have gotten away with it too, if it weren’t for those darn kids, errr, her opening her big mouth.
I won’t mention what it was online but they do test for it now.
Here’s some happy news - Texas let her go. She’s out there under another name; having been released.
sigh
Got it thanks for the explanation.
