City of Missoula v. Iosefo
330 P.3d 1180
Mont.2014Background
- Off-duty Missoula officer Mark Fiorentino, working as a private security guard at a festival, observed Martin Iosefo drive the wrong way into a parking garage exit, drive through yellow caution tape into a pedestrian festival area, and collide with a plastic barricade.
- Fiorentino ordered Iosefo to remain in his vehicle; Iosefo exited, walked away, resisted being detained, waved his arms, and acted agitated and unpredictable.
- Fiorentino attempted to detain Iosefo, called 911, threatened to use force (including gunpoint) when Iosefo would not remain, and on-duty Missoula officers arrived minutes later and took custody.
- Iosefo was charged with careless driving, aggravated DUI, and refusal to submit to a breath test; he moved to suppress the arrest as lacking probable cause under the citizen’s arrest statute.
- Municipal Court denied suppression; Iosefo pleaded guilty to DUI (reserving the suppression issue) and appealed. The District Court affirmed; the Montana Supreme Court granted review on the sole issue whether the off‑duty officer had probable cause to arrest.
Issues
| Issue | Plaintiff's Argument (City/Fiorentino) | Defendant's Argument (Iosefo) | Held |
|---|---|---|---|
| 1. Whether an off‑duty officer may effect a citizen’s arrest for a non‑jailable offense | Citizen’s arrest statute requires only probable cause of an "offense" and immediate arrest when circumstances demand — no jailable‑offense limitation | Arrest was invalid because citizen arrests should be limited to jailable offenses | Held: No jailable‑offense requirement; officer needed probable cause and circumstances requiring immediate arrest, which were present |
| 2. Whether Fiorentino had probable cause (vs. mere suspicion) to arrest Iosefo | Fiorentino observed dangerous, erratic driving and property damage that a reasonable person could view as probable cause for offenses (e.g., careless driving) and that required immediate arrest to protect public safety | Fiorentino only had particularized suspicion (and said he couldn’t tell if Iosefo was intoxicated); arrest improperly used to investigate a suspected DUI | Held: Fiorentino had probable cause based on dangerous driving and collision with a barricade; the circumstances required immediate arrest for public safety; arrest was not merely investigatory |
Key Cases Cited
- State v. Updegraff, 363 Mont. 123, 267 P.3d 28 (Mont. 2011) (off‑duty officers may make arrests under the same circumstances as a private citizen; citizen’s arrest contemplates public safety)
- State v. Bauer, 307 Mont. 105, 36 P.3d 892 (Mont. 2001) (warrantless arrests for non‑jailable offenses require special circumstances—safety concerns—to justify immediate arrest)
- State v. Williamson, 290 Mont. 321, 965 P.2d 231 (Mont. 1998) (probable cause exists when facts known to an officer would lead a reasonable person to believe an offense is being or has been committed)
