A North Carolina sheriff searching for clues into the slayings of four family members says investigators are focused "in two directions" that could garner an arrest.
Catawba County Sheriff David Huffman said Tuesday investigators are working nonstop to find the person who killed Lisa Saephan and her three children -- 20-year-old Melanie, 18-year-old Pauline and 3-year-old Cody.
Huffman said evidence is taking investigators in two directions, but he wouldn't elaborate. He said no one has been ruled out as a suspect.
Saephan and her children were found shot or stabbed to death last Thursday in their home near Conover, a small town about 40 miles northwest of Charlotte. Officials have said their father and Saephan's husband, Brian Tzeo, was at work at the time.
