Michael Otto was 8 when he disappeared from Deltona, Florida, on October 22, 2013, alongside his 9-year-old sister Thalia Otto and their mother, Yessenia Suarez. The family vanished after a night in which Yessenia had returned from her mother’s house to her own home with the children; she had earlier been involved in escalating conflict with her husband and the children’s stepfather, Luis Toledo, including a confrontation at her workplace the same day.

When Yessenia did not check in the next morning, her mother alerted authorities. Officers found the family home empty and one of Yessenia’s vehicles abandoned in a nearby parking lot. Investigators later reported traces of the children’s blood in the home and in the vehicle. No bodies have been recovered and the family’s whereabouts remain unknown; investigators say foul play is involved.

Does anyone have information about Michael, Thalia or Yessenia’s last known movements or saw the vehicle after October 22, 2013?
