Seeing defendant in the house of another was justification for entry into the home to arrest him on a warrant under Steagald. United States v. Terrell, 2017 U.S. Dist. LEXIS 175483 (E.D. Mich. Oct. 24, 2017).
Defendant was stopped for erratic driving and was apparently under the influence. The officer could smell the faint odor of marijuana. That justified a search of the vehicle under the automobile exception. State v. Donovan, 2017 Mo. App. LEXIS 1096 (Oct. 24, 2017).*
