(AP Photo, Kansas City Police Department) (Newser) – Missouri police have launched a massive manhunt for a baby girl who vanished from her crib in the middle of the night. "We've exhausted everything we can at the original scene," said a police spokesman. "We've opened up the crime scene and are doing everything we can." A neighbor reported seeing someone walking down the street at night with a baby in a diaper about the time 10-month-old Lisa Irwin vanished. Lisa's mom put her to bed about 10:30pm, and when her father returned home from work before dawn she was gone, the parents told police. "The window and the screen appeared to have been tampered with," Officer Darin Snapp told ABC News. "We are conducting an area canvas, knocking on doors and talking to anyone that was in the area that night." The police spokesman said the parents' account does not appear "hinky" in any way, and they're cooperating with cops. "We are interviewing family and friends just to eliminate everyone's that close to the family as suspects," Snapp said. Police currently have no solid leads or suspects.
