   U.S. Court of Appeals Case No:  22-1379
   U.S. District Court for the Northern District of Iowa - Central   
   [PUBLISHED] [Gruender, Author, with Smith, Chief Judge, and Stras, Circuit 
   Judge] 
   Criminal case - Criminal law and Sentencing. Admission of information 
   about a codefendant's prior drug conviction did not prejudice defendant; 
   the district court did not err in refusing to give defendant's proposed 
   instructions on conspiracy, including a government-agent instruction and a 
   buyer-seller instruction; nor did the court err in refusing to instruct 
   the jury that defendant must have knowledge of the drug type and quantity 
   in order to be guilty of conspiracy; evidence was sufficient to show that 
   defendant conspired to distribute methamphetamine; the district court did 
   not err in calculating the amount of drugs involved; the amount of drugs 
   does not need to be found by clear and convincing evidence, as the proper 
   standard is the preponderance of the evidence; no error on this record in 
   imposing an enhancement under Guidelines Sec. 2D1.1(b)(1) for possession 
   of a firearm.
