United States v. Jurother Alston, Jr., 941 F.3d 132

On Dec. 11, 2017, Capt. Raheem Aleem stopped Jurother Alston after observing a red‑light violation and saw Alston reaching deep under the passenger seat in a way that suggested he might be reaching for a gun.
Aleem activated lights; Alston initially failed to stop, then slowly stopped after striking a parked car; Alston produced a small bag of marijuana voluntarily and handed it to Aleem.
Aleem, skeptical and concerned about a weapon, asked for more contraband; Alston later produced a black bag (marijuana, scale, bags) and—after Aleem assured him he would not be arrested—admitted a gun was under the passenger seat.
Aleem searched and recovered a loaded, stolen Glock. Meanwhile a task force deputy, who had an independent tip that Alston (a felon on probation) had a gun, told Aleem to detain Alston; task force officers then arrested him.
The district court found the initial admissions voluntary but suppressed the later statements induced by Aleem’s assurance not to arrest; nevertheless it admitted the gun under the inevitable discovery doctrine because Aleem had probable cause under the automobile exception and would have searched.
Alston pleaded conditional guilty to possession of a firearm in furtherance of a drug crime, reserved his right to appeal the suppression ruling, and appealed. The Fourth Circuit affirmed.

Issue	Plaintiff's Argument	Defendant's Argument	Held
Whether the entire encounter was custodial requiring Miranda warnings	Alston: interaction was custodial interrogation; failure to give Miranda requires suppression of all evidence	Govt: encounter was noncustodial; Miranda not triggered for initial voluntary statements	Court: initial interaction not custodial; district court correctly excluded later involuntary statements but not all evidence
Whether Alston’s statements were voluntary	Alston: all statements were involuntary and should be suppressed	Govt: early admissions (marijuana) were voluntary; only later admissions were involuntary	Court: first admissions voluntary; later admissions after promise not to arrest were involuntary and suppressed
Whether officer impermissibly prolonged the stop (Rodriguez)	Alston: Aleem exceeded scope/detained him unlawfully	Govt: voluntary admission of marijuana supplied reasonable suspicion/probable cause to investigate/search	Court: no Rodriguez violation — the marijuana admission gave grounds for further detention/search
Whether the gun was admissible under the inevitable discovery doctrine	Alston: gun was the fruit of involuntary statements and should be suppressed	Govt: even absent involuntary statements, Aleem had probable cause under the automobile exception and would have searched and found the gun	Court: Govt proved by preponderance that lawful search was available and would have been conducted; gun admissible
