Washington (CNN) Former President Barack Obama penned a handwritten note to a former inmate to whom he granted clemency, praising her for making the dean's list at Southern University, where she enrolled after she left prison.

Danielle Metz's story was first reported on by The Hechinger Report, a nonprofit news organization that reports on education. In 1993 at the age of 26, she was sentenced to serve three life sentences, plus another 20 years, for drug-related offenses related to her husband's cocaine trafficking ring, according to the report.

She told The Hechinger Report that she wishes she was able to thank Obama, who granted clemency to hundreds of individuals during his time in office. A majority of the commutations involved drug related charges.

"You don't know what you did for me. I'm finally coming into my own. I made the honor roll," Metz said.

USA Today also published The Hechinger Report's story, and a few days later, Obama responded to her in a letter.
