Police searching for missing 20-month-old toddler Quinton Simon have seized new evidence they think will "move this case forward".
The boy disappeared from his home in Savannah, Georgia, over a week ago wearing a light blue Sesame Street shirt and black trousers.
Search warrants have been executed, supported by the FBI, and police continue to interview people they suspect may have information related to the case.
Officers have also returned to his home where he was last seen along with a team of search dogs and investigators.
An update yesterday (October 11) from a spokesperson for Chatham County Police Department, read: "We've seized evidence that we believe will help move this case forward & we're now working to analyze the evidence to see where it leads us.
"We continue to pursue all avenues to bring Quinton home, following all leads and evidence."
Last week Chatham County Police Chief Jeff Hadley, who is heading the search, told reporters: “We’re going to hold out hope that he’s still alive, and that we can find him and bring him home safe to his parents.
“But, we’ll continue to look at all angles and exhaust all investigative avenues.”
The toddler was last seen at around 9.40am at his home in the 500 block of Buckhalter Road, Savannah, on Wednesday October 5.
The case remains a missing child investigation.
Police are calling on anyone who thinks they may have seen the boy to call 911. Other tips and information should be sent through the department’s online tip form found.
Police previously said they do not suspecthe was taken as part of a custody battle.
The toddler's babysitter told a local paper that she was supposed to watch Quinton the day he vanished but received an 'odd' message early in the morning.
Diana McCarta said: “I got a text this morning saying they would not be here — would not be babysitting them at 5:29 [a.m.]. Which was kind of odd because I have them even when [their mum] doesn’t work”.
She continued: “My Heart is broken. I’m not his mother. I’m not his family. But I love him very much And I just don’t know what could happen.
“The police did a really good job of looking and where does a 1-year-old go. They’ve covered a lot of ground.”
