A cash reward is being offered to anyone who can provide information that leads to the whereabouts of Elaina Steinfurth.
The 18-month-old girl has been missing from an East Toledo home since June 2.

Police and federal agents have done extensive searches, primarily in East Toledo, looking for the girl. She was reported missing after her father, Terry Steinfurth II, went to pick up his daughters from his estranged wife, who was staying on Federal Street.
The 4-year-old was there, but the girls' mother, Angela Steinfurth, said the younger girl was missing.
No charges have been filed.
