Nieves is the mother of Yessenia Suarez. Yessenia and her two children went missing in 2013, and her husband was later convicted of their presumed deaths even though the three bodies were never found.

Jonathan's wife, Jazmine Suarez, believes he left because he was struggling to cope with his sister's loss. 

"I just think it kind of has eaten him up, and now he’s kind of like, ‘I need to find my sister,’" she said.
