FOX: Four haunting words were spray-painted in red on a wall of the Illinois home where a woman and her sons were found strangled: "I told you so."

That and other new details have emerged since Wednesday, when Chris Coleman, 32, pleaded not guilty to three counts of first-degree murder, accused of killing his 31-year-old wife, Sheri Coleman, and their children, 11-year-old Garett and 9-year-old Gavin.

Major Case Squad Deputy Commander Major Jeff Connor told FOX affiliate KTVI-TV that it was not one piece of evidence but several factors that prompted police to arrest Coleman on Tuesday. He is being held without bond.

"I can tell you this investigation took us all over the place, several states, businesses, worship centers, residential areas, all over, so I don't want to key in on any one piece of evidence," Connor told KTVI.

He said the bodies of Sheri, Gavin and Garett were found, strangled, in separate bedrooms in the family's Columbia, Ill., home, and that a basement window of the home was found open on the morning of May 5.
