Police use search dogs at the home of missing toddler Quinton Simon

Police brought search dogs to investigate the home of 20-month-old Quinton Simon in Savannah, Georgia, who disappeared from the home a week ago.

The Chatham County Police Department said a team of search dogs and investigators spent Wednesday “gathering and analyzing evidence” looking for little Quinton.

A day earlier, Chatham County Police said they had “seized evidence” that they believed would “help move this case forward” as it neared the one-week mark.

The toddler was last seen in an indoor playpen around 6am on October 5. About three hours later, he was reported missing by his 22-year-old mother.

Investigators have previously searched the family’s home, as well as the family’s backyard pool, a nearby pond and other outdoor areas where the boy may have wandered. FBI agents assisted in the search.

Police initially said they did not suspect foul play in Quinton’s disappearance, but are now investigating whether a crime was involved.

The boy’s mother believed someone may have taken him from her home when she called 911 to report her missing, according to the 911 call received by WJCL.

The boy was last seen in the house by his mother’s friend. The boy’s biological father is not believed to be involved, police said.

Quinton’s maternal grandparents have custody of him and his 3-year-old brother, local ABC affiliate WJCL reported.

Chatham County Police said they plan to hold a media briefing Thursday to update the public on the case.
