State v. Jamison, 1 CA-CR 22-0575

Dustin Jamison, working as an informant for the ATF, was arrested in 2019 after being found with a bag containing methamphetamine and a needle, neither authorized nor reported to his handler.
Agent Ogg, Jamison’s ATF handler, discovered Jamison at a known drug dealer’s house and later observed signs of methamphetamine use during a vehicle stop.
Jamison admitted to possessing the methamphetamine and to previous drug sales, and further admitted obtaining the drugs from the dealer, Jessica.
Evidence (methamphetamine, bag, and needle) was seized and entered into evidence; Jamison was charged and convicted of possession of dangerous drugs for sale and possession of drug paraphernalia.
On appeal, Jamison argued improper chain of custody, insufficient evidence, and that the trial court erroneously restricted cross-examination on chain of custody.

Issue	Plaintiff's Argument	Defendant's Argument	Held
Chain of custody of evidence	Drugs and paraphernalia not sufficiently authenticated; chain of custody incomplete	Evidence adequately authenticated; no evidence of tampering; markings and testimony sufficient	No error; foundation for admission sufficient
Sufficiency of the evidence	Convictions should be vacated because evidence was improperly admitted; identity and weight of drugs not proven	Substantial evidence supported the jury’s verdicts; forensic analysis and testimony sufficient	Substantial evidence supported both convictions
Restriction of cross-examination	Court erred by sustaining objections to chain of custody questions during Detective’s testimony	Detective lacked knowledge; form discussed already; questions irrelevant	No abuse of discretion in sustaining objections
Denial of Rule 20 motion (judgment of acquittal)	Superior court improperly denied; insufficient evidence post-evidence	Evidence supported essential elements; jury properly resolved factual disputes	Properly denied; verdicts supported by evidence
