NEWER VERSION: See Wife charged with killing husband
Holts Summit police on Tuesday arrested Sandra Plunkett, 37, in the fatal shooting of her husband, Paul Plunkett, on New Year's Day.
At a Tuesday afternoon news conference, officer Marc Haycook said police expect charges will be filed within a few hours.
Sandra Plunkett reported at about 12:49 p.m. on Saturday that her husband had been shot inside his home. She initially told police that she was outside the home when she saw a man in camouflage with a gun walking down the street. She said she entered her home and found her husband on the floor, shot in the back of the head.
But Haycook said "all leads pointed to Mrs. Plunkett as being the suspect."
He said she is cooperating with police, and will be held in the Callaway County Jail.
He said his department, with help from area agencies, tracked down 60 leads from the public.
Haycook didn't offer a motive for the killing or say what specific evidence led to the arrest.
