Authorities continued to search through wooded areas, an industrial park and sewers in search of missing 10-month-old Lisa Irwin today.
Irwin's parents, Deborah Bradley and Jeremy Irwin, made an emotional plea for their daughter's safe return in a news conference recently.
"We just want our baby back," said Deborah. "Please bring her home. Our two other boys are waiting for her. Please just drop her off anywhere. We don't care. Just somewhere safe where she can come home."
Lisa was discovered to be missing when her father, Jeremy, reportedly returned home at 4 a.m. after an overnight shift early Tuesday. Jeremy discovered an open window in front of the house, and quickly went to check on his sons, 6 and 8, and Lisa, who was discovered to be missing.
"We just urge anyone that has any kind of information as to where she is or who she is with or anything to please call the TIPS Hotline or police," Jeremy said.
Since Lisa Irwin went missing late Monday night, early Tuesday morning, authorities have followed up on upwards of 50 leads, police say. Unfortunately, the investigation continues to move slowly.
"We really haven't - still at this point - developed any hard information that we can go forward with," said Captain Steve Young, a spokesman for Kansas City police.
"The only thing we know absolutely is that there should have been a 10-month-old in that house and there wasn't. We are doing everything we can to find that child."
