Elizabethtown, Ky. ? A man charged with killing his four young children and assaulting his wife was ordered held without bail Saturday as the bodies were laid to rest.

A funeral was held Saturday at the Islamic Center in Elizabethtown, south of Louisville. Islamic tradition calls for burial as soon as possible after death.
