She adds, "I will never forget this story, it was a real thriller."

As for the Dateline: Secrets Uncovered season 10 premiere, the new episode follows the death of Frank Rodriguez. Per Oxygen, Rodriguez "was a Navy vet who dedicated his life to helping needy children, not a guy with many enemies. Figuring out who would want him dead was a challenge. How he died was also a mystery investigators needed to solve to catch his killer."

Watch the new trailer below.

Dateline: Unforgettable kicks off Monday, Mar. 8 at 8 p.m. on Oxygen.

Dateline: Secrets Uncovered season 10 premieres Thursday, Mar. 11 at 8 p.m. on Oxygen.
