(CBS/AP) LONDON - Authorities in England have indentified the remains found on one of Queen Elizabeth's estates as a missing 17-year-old girl.

The decomposed remains found by a dog walker on New Year's Day are those of Alisa Dmitrijeva, who was reported missing from her home in eastern England in August.

Dmitrijeva's mother told Britian's The Daily Mail newspaper that she feels she is partly to blame for her daughter's fate because the two fought often in the days and weeks leading up to Alisa's disappearance.
