UPDATE (10/10 2:40PM) -- Police launched another investigation Thursday near where Diane Ruiz was last seen on Monday. They say a body has been found with "characteristics" of Diane.
UPDATE (10/10): Cape police say they have a person of interest who may be connected to both women. Two sources - including a former girlfriend of the person of interest - tell Fox 4 it was a family member who turned him in.
We are choosing not to name that man because Cape Coral Police have not yet charged him yet.
That person is being held on no bond in jail on other charges.
