[8] The length of an investigative stop must be no greater than is necessary to effectuate the purpose of the stop. See State v. Soukharith, 253 Neb. 310, 570 N.W.2d 344 (1997). The U.S. Supreme Court held that an investigative stop that lasted 90 minutes, where the police did not diligently pursue the investigation, was not reasonable, but declined to establish a strict time limitation on what is reasonable. United States v. Place, 462 U.S. 696, 103 S. Ct. 2637, 77 L. Ed. 2d 110 (1983). Likewise, this court has held that "'rigid time limitation' or '"bright line"' rules are not determinative of [the] legality [of investigative stops]." State v. Chronister, 3 Neb. App. 281, 288, 526 N.W.2d 98, 104 (1995), quoting United States v. Sharpe, 470 U.S. 675, 105 S. Ct. 1568, 84 L. Ed. 2d 605 (1985).
This one (United States v. Place, 462 U.S. 696, 103 S. Ct. 2637, 77 L. Ed. 2d 110 (1983). ) was for 90 minutes, however I'm pretty sureI read of one that said a reasonable time limit for a silent stop, one where the driver maintains his/her silence and when no other contributing factors are involved that something like 20 minutes was the reasonable length. Also that was, i believe, a supreme court case. I'll keep looking for it. Sorry i don't have it at my fingertips, i've been asked to show proof of this befoer but I can't remember if I ever found it, when/if I do I'm bookmarking it.
