Two years have passed since a 10-month-old baby was reported missing from her Kansas City home and the case is growing cold.

Deborah Bradley and Jeremy Irwin have said they believe someone kidnapped their daughter, Lisa Irwin, 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, even sifting through a Kansas landfill. No one has been charged. There is a $100,000 reward offered to anyone with information that will bring the child home.

The family and their supporters will hold a prayer vigil Saturday night at their home, the Kansas City Star reported. In an effort to show what Lisa would look like today, an age-progression photo of her from the National Center for Missing and Exploited Children has been released.

"I cannot force the people who know where Lisa is and who might have her into telling us. I have no control over that," Bradley said. "You do what you can for your baby, because it is your job as a parent to protect your child, and I wasn't able to protect her from the bad guys."

Police and a private detective are still investigating, but Kansas City Police Capt. Tye Grant said the tips and leads have slowed considerably, down to about one a week. During the first year, detectives worked more than 1,600 leads and countless baby sightings.

Bradley and Irwin have repeatedly said they did not harm Lisa and had nothing to do with her disappearance. Bradley said she and Irwin think someone took Lisa and is raising the child as his or her own.

"When she comes home and (with) all of the hateful things that certain people have said, they have to answer to their maker for judgment," she said. "I will have my daughter back, and I will be vindicated, and those people that spent all of that time judging me will be miserable, but we won't.

"We will be happy again."
