On Monday evening Emmett Trapp fell asleep in his family's Arizona home. When his mother awoke around 8 p.m., the little boy was nowhere to be found.

Search teams have been utilizing helicopters along with dog units, but Emmett is still missing.

"A little 2-year-old is gonna cry out, is going to be uncomfortable, is going to get hungry," Dwight D'Evelyn of the Yavapai County Sheriff's Department told KPHO. "We haven't heard that happen. There's been no trail that leads up anywhere that we've been able to track, so yeah, it's odd."

Authorities lowered cameras down well shafts Tuesday and hope to get hold of infrared cameras to use on a helicopter to scan the land for Emmett's body heat, but if the boy seeks refuge behind a shrub he won't be seen, reports KPHO.

Emmett was wearing a pajama top and diaper at the time he was reported missing.

The case of Sylar Newton, who went missing on July 25, is now considered a criminal investigation, as police believe the 2-year-old was kidnapped from a campground and is likely dead.

Yavapai County Sheriff Steve Waugh declined to name any persons of interest in the criminal investigation into Sylar Newton's disappearance, but authorities are looking into custodial issues involving the boy's adoptive family and his biological mother.

Anyone with information about Emmett or Sylar is urged to contact the Yavapai County Sheriff's Office at 928-771-3260.
