Towanda ? Authorities in a south-central Kansas county will conduct a news conference Monday about the apparent disappearance of a boy nearly a decade ago.

The news conference in Butler County comes after investigators found something Wednesday at the Pine Ridge mobile home park south of Towanda, where the boy once lived.

For now, officials will only say that the discovery provided some answers about the case. Sheriff Craig Murphy said authorities have been unable to find any trace of the boy since 1999, when he was 11 or 12.
