BERLIN (AP) — British investigators are excavating a riverbank in western Germany more than three decades after a soldier's 2-year-old daughter vanished, in a renewed push to try and find out what happened to her. Royal Military Police are taking the lead on the investigation and are being assisted by German authorities with police dogs in their forensic search of the banks of the Alme river, in the western city of Paderborn, senior investigating officer Warrant Officer Class 1 Richard O'Leary told reporters on Thursday. Katrice Lee vanished on her second birthday on Nov. 28, 1981, while out shopping with her mother on the outskirts of Paderborn, near the British military base where her father was stationed.
