The first grader was last seen playing in her front yard after taking the bus home from Springdale Elementary School on Monday, Antley said.
After finding the item, investigators were quickly organising a methodical search of nearby woods that had been searched before when Cayce Public Safety Director Byron Snellgrove found Faye's body, Sgt Antley said.
Shortly before it was announced that a missing SC 6-year-old girl was found dead in a suspected homicide, the girl's grandmother posted a heartbreaking video of the child singing "You Are My Sunshine".
He wouldn't identify the evidence but said the item was listed on Faye's Federal Bureau of Investigation missing poster.
Lexington County Coroner Margaret Fisher said autopsies were scheduled for Saturday.
At Friday's press conference, during which he appeared near tears several times, Antley said, "Yesterday was a tough day - possibly the toughest day of many law enforcement careers". Her body was found somewhere in her neighborhood on Thursday morning.
A three day search for a missing 6-year-old girl in the U.S. has ended in tragedy with the discovery of her body in a wooded area after vital evidence in a rubbish truck led police to her location. Antley said that based on preliminary information, they believed Faye hadn't been at that location for a very long time. He declined to specify, but said authorities believe there is no active threat to the community, adding that police are not looking for any additional persons of interest. "Taylor's house to Faye's house are 100 to 150 feet (30 - 45 metres) from each other", Sergeant Antley said.
More than 250 officers searched for the girl over three days.
Police have not made any arrests and have no suspects, Antley said, but authorities are still investigating and are keeping details about the case limited for that reason. Police were called at 5 p.m.
Faye's mother, who could be heard crying on the call, went on to give a description of her daughter.
