Just because she was born in New York does not mean she wasn’t from Somali heritage.
Are you kidding me?
When you're in a hole, stop digging.
She was born in NYC in 1979 to a NYC woman - Idella Carey.
That's 1979.
In other words, Miriam Carey was 14 years old when the Battle of Mogadishu happened - the event that resulted in the wave of Somali migration to the US.
Provide a single shred of evidence that she has any Somali background whatever.
You cannot.
You just made something up based on zero evidence and can't admit to your fabrication.
