United States v. Asmerom Keleta, 949 F.3d 1082

Asmerom “Ace” Keleta owned Eriace Enterprise, LLC, operating U‑City Tax Service; the IRS’s Scheme Development Center flagged an unusually high and suspicious pattern of credits and unverifiable income on returns prepared by Eriace.
An undercover IRS agent paid Lewis at a U‑City branch to inflate a refund; Lewis fabricated self‑employment income and charged a fee; the IRS also received anonymous tips and found business account withdrawals that looked personal.
Agents obtained and executed a search warrant for the U‑City branch (April 13, 2013), seizing computers, files, phones, and a signature stamp; Keleta was later indicted for conspiracy and aiding in preparing false tax returns.
At trial Lewis and several customers testified that Keleta prepared false returns; Paulos and Lewis pleaded guilty; Keleta defended mainly on misidentification and documentary signature evidence.
During government rebuttal closing, prosecutor improperly suggested Paulos had been present in the courtroom during trial to rebut the misidentification defense; defense objected and moved for a new trial (denied).
Jury convicted Keleta of conspiracy and one count of aiding/assisting a false return; on appeal the Eighth Circuit affirmed the convictions, found the prosecutorial remark improper but harmless beyond a reasonable doubt, vacated the sentence, and remanded for resentencing due to an improper § 3B1.1(a) role enhancement.

Issue	Plaintiff's Argument (Keleta)	Defendant's Argument (Government)	Held
1) Motion to suppress warrant evidence	Affidavit contained false/misleading stats and omissions that vitiate probable cause; good‑faith exception inapplicable	Affidavit described an unusually high, non‑verifiable pattern and undercover corroboration; even if some errors existed, affidavit still established probable cause or falls within Leon good‑faith exception	Affidavit supported probable cause without disputed statements; suppression denial affirmed
2) Prosecutorial misconduct from closing remark claiming Paulos was in courtroom	Prosecutor’s statement was untrue, impermissibly introduced facts not in evidence, and deprived Keleta of a fair trial	Government conceded the comment was misleading but argued the defense opened the door and evidence of guilt was strong enough to render any error harmless	Remark was improper and misleading, but error was harmless beyond a reasonable doubt as to the convicted counts; convictions affirmed
3) Four‑level role enhancement under U.S.S.G. § 3B1.1(a)	Enhancement invalid because government failed to prove five or more criminally responsible participants; customers were unwitting victims, not participants	Government pointed to Keleta, Lewis, Paulos, and testimony from several customers (and later argued others) as participants	Government failed to prove five criminally responsible participants; enhancement vacated and case remanded for resentencing
