Lee Ford, 33, appeared at Truro Magistrates Court on
Friday and was remanded in custody for a week.
The move comes after the discovery of five bodies near the town of
Helston.
Police have been investigating the disappearance of a
36-year-old woman, Lesley Ford, and her four children Craig, 13, Stephen,
14, Anne-Marie, 16, and Sarah-Jane, 17.
They were last seen five weeks ago but police were
only alerted at the end of September when Mrs Ford's concerned brother,
from Hampshire, contacted them.
The first body was discovered by police in the
woodshed of the family bungalow in Carnkie, near Helston, Cornwall, at
0330 BST on Thursday.
Two other bodies were later found in the same shed
underneath piles of wood.
Two further bodies were recovered from a field on
farmland on Friday at Tresluswell, near Penryn, Cornwall.
Those bodies were taken from the site in a hearse
just after 1030 BST.
A police tactical aid group is continuing to search
the ploughed potato field.
The four missing children all have the surname
Tranter from Mrs Ford's previous marriage.
Sarah-Jane worked at a nearby McDonald's restaurant
and the other three children attended Helston school.
