KANSAS CITY, Mo. -- Three years ago this weekend baby Lisa Irwin disappeared from her Kansas City northland home in the middle of the night.
Her parents, Deborah Bradley and Jeremy Irwin, believe their daughter was kidnapped.
Detectives are still following leads in the investigation, and her parents hope people will continue to use the TIPS Hotline with any information that might be helpful.
"She's got to be somewhere," Irwin said. "She's been to the doctor or been to a daycare or been around other people or to the grocery store, so she's got to be out there somewhere."
During a one-on-one, Bradley and Irwin showed FOX 4's Kathy Quinn an age-enhanced picture of the little girl who turns four next month.
Bradley mother says she knows her daughter will come home some day. She says it helps that they now have a working relationship with the Kansas City Police Department. Initially, that relationship had been troubled.
"Lisa's kidnapping surely rocked the Kansas City Police Department and the FBI, and I think it hit close to home for all of them too," Bradley said. "None of this comes with instructions, you just have to do what you think is right."
In this third year of waiting, the emotional strain for the family has been the worst.
“As far as Lisa, there’s not really a moment that goes by during the day that she's not on my mind,” Bradley said. “But I try to stay focused on the here and now so that I can function and take care of my responsibilities.
The family is holding a vigil on Saturday, the anniversary of Lisa’s disappearance. It’s set to begin at 7 p.m. at the family’s home.
