The Delphi town Sheriff who testified was not in charge of the search. He was helping out because these were Delphi children. He said he personally went home at around 2 am.
The Bridge is outside Delphi city limits. The Carroll County Sheriff was in charge.

"Carroll County Sheriff Toby Leazenby said ... Crews searched for the missing teens into the night, but because of the dark, the search was slowed around midnight. Crews will regroup and continue their search efforts first thing in the morning. "
Also, the Prosecution is currently presenting their case. Their case has nothing to do with what time, or was the search 'called off'.
That issue is the preoccupation of the defense. So the defense will have to call witnesses about when/whether the search was 'called off'. That won't happen for, probably, weeks.
