Read the article. Her mother was an artist and she did reproductions, especially Renoir.
Looks like she needed money and decided to chance it.
A picture of her from 2010 in blackjack school.
Fuqua's mother graduated Goucher College with a degree in fine art, before in 1957 receiving a masters degree from the Maryland Institute College of Art.
Hard to tell if she received her masters in 1957 or fine art degree, but I assume it was the fine art degree.
From her picture she appears to have been born in the laste 40's, but more likely in the 50's. So she was either not born or the youngest art thief in history.
Extremely high probability she did not steal it. Maybe they are trying to determine if mom stole it based on the brother's initial accusation that it has been in the family for 50 to 60 years.
