And in Jessica Lumsford's case (missing 2/24)they search every one MH and fail to check a closet. LE didn't find Jessica until 3/19 across the road from her home.
They found her because a confess. Jessica's case bothers me the most
snips
The detectives did a
cursory search of the premises, looking for signs of either Couey or Jessica. Unfortunately they failed to check the closet in the room where Couey had been staying.

Nineteen days after Jessica Lunsford was first reported missing, detectives returned to Dixon's home on March 14. Authorities were still trying to locate John Couey. They searched the trailer again, and this time they checked the
closets but found nothing incriminating. However, in the bedroom where Couey had slept,
they found blood on the mattress
IMO that all they did in the search for Hailey (cursory check)
