Bonneville County Sheriff's Department issued an Amber Alert for 10-month-old Zeke Best on Friday. His father, Jeremy Best, 48, was suspected of kidnapping him.

The Teton County Sheriff's Department had been searching for the baby since Thursday night when they responded to open line 911 call from his home in Victor, Idaho.

Responding deputies identified the man as Best, and put him in a patrol car until an ambulance arrived. They also found his black Chevy SUV, down an embankment off the roadway and Zeke dead on the scene.

Suspect transported to medical center morning of wife's death

According to a press release from Bonneville County Sheriff's Department, about 12 hours before his wife was found dead, Best was found walking around the Swan Valley General Store naked at around noon on Thursday. He had been transported to Eastern Idaho Regional Medical Center by ambulance, but it's unclear exactly when he'd been released from the medical center.

"There was not an indication at that time his behavior would continue, escalate, pause, change, or stop - which is why he was taken to the appropriate place, the hospital, for evaluation," the Bonneville County Sheriff's Department said in a Facebook comment.

"We can’t discuss nor do we know what kind of action was taken at the hospital, other than to say with everyone we’ve dealt with in similar situations our experience has been they are taken care of appropriately and to the best of their ability, as much as patients and family members will cooperate in that effort. We must work within the bounds of the law in every situation based on what we know at the time."
