(AP) — Almost two years have passed since a 10-month-old baby was reported missing from her Kansas City home.

Family and supporters of Lisa Irwin’s parents will hold a vigil Saturday night.

Deborah Bradley and Jeremy Irwin have said they believe someone kidnapped the baby from her crib. Jeremy Irwin said that when he returned home from a late shift on Oct. 4, 2011, the front door was open and the baby was missing.

Police and the FBI conducted extensive searches, but no one has been charged. A $100,000 reward is being offered to anyone with information that brings the child home.

Police say their investigation continues, but the calls and tips have dwindled. A family attorney says a private detective continues to investigate.
