WEEPING WATER, Neb. (AP) — Investigators say a Nebraska man facing an assisted suicide charge in his Florida girlfriend's death believed she had stage-four cancer, but an autopsy didn't find any tumors. Cass County sheriff's deputies charged Matthew J. Stubbendieck, 41, of Weeping Water last week in the death of 38-year-old Alicia Wilemon-Sullivan of Orange City, Florida. Authorities said Stubbendieck reported that Wilemon-Sullivan had killed herself and led them to her body Aug.
