The only episode that comes to mind is the one in SVU where a girl "tricked" a family into saying she was their runaway daughter because thy looked the same. Only to find out the family knew that the original daughter was dead but just went along with it to cover up the murder.
Not even a picture to see if they look the same. >

That might've worked 100 years ago. Not so much today. >

I swear this was a law and order episode I saw as a kid.
