Buckeye police said they are still hopeful Jesse Wilson will be found "alive and safe" but advised this could turn out to be a "recovery operation."
According to a Facebook post by the Buckeye Police Department, "stopping is not an option" for police, the FBI and MCSO who keep searching for the missing boy.

On Sunday, police said the reason why volunteers are no longer assisting in the search is because this could become a recovery operation with the possibility of "locating a deceased person." However, they are calling that the worst case scenario and stressed they are still hopeful the boy will be located alive.
On Thursday, local, county and federal officials combed through an area west of Miller Road in Buckeye , but after hours of searching came up empty-handed. Police said they have been making these types of large searches since the beginning of the investigation.
Police also said Crystal Wilson, Jesse's mother, is cooperating with officials.
Anyone who knows where the boy may be or know details of his disappearance are encouraged to call the tip line at (623) 349-6411.
