In Hinkle v. Beckham County, Oklahoma, the Tenth Circuit held that an officer had probable cause to arrest based on information that the person arrested owned (or had a connection with) a trailer that had been reported stolen. It did not matter that the person informed the officer that the information was mistaken---"a soon-to-be-arrestee's bare proclamations of innocence" do not dissipate probable cause.
But the arrestee's body-cavity strip search upon admission into the jail was unreasonable under the Fourth Amendment. There was no justification at the time of the search--that is, no decision had been made that the arrestee would be placed in the jail's general population (in fact, he was placed in segregation), and there was no cause to believe that he was concealing evidence of a crime.
In United States v. Cristerna-Gonzalez, the Tenth Circuit affirmed Mr. Cristerna-Gonzalez's drug convictions, finding no reversible error in (1) the unobjected-to admission of expert law-enforcement testimony (no plain-error); (2) the unobjected-to admission of modus-operandi evidence consistent with Fed. R. Evid. 404(b) (no error, much less plain error); or (3) the admission over objection of irrelevant and prejudicial testimony suggesting a connection between this case and a notorious drug cartel (this was error, but it was harmless).
Sentencing: Procedural & Substantive Reasonableness
In United States v. Pena, a carjacking/gun/methamphetamine case, the Tenth Circuit affirmed an upward-departure sentence of 360 months' imprisonment--more than twice the high end of Mr. Pena's guidelines range. The district court addressed the statutory factors and adequately explained the sentence.
