Your Bag, Their Warrant: When Police Can Search a Visitor’s Backpack

State v. Porter, No. 24–1254 (Iowa 2026) 

TL;DR

The Iowa Supreme Court held that officers executing a premises search warrant can search a visitor’s backpack if it is not in the person’s physical possession and could contain the items listed in the warrant. The court rejected arguments based on privacy and abandonment, emphasizing that the case is about scope of the warrant—not whether a warrant was needed.

Why it matters:

• Containers on scene = searchable if they can hold the evidence

• Ownership doesn’t matter as much as possession at the time of entry

• Denying ownership can also destroy your privacy interest

Limits:

• Officers cannot search a person or items physically attached to them without separate probable cause

• The rule hinges heavily on whether the item is in actual possession

Facts

In late 2023, Iowa narcotics officers built a case against a house in Des Moines using multiple controlled buys of methamphetamine. Based on that investigation, they obtained a premises search warrant for the residence.

On the morning officers planned to execute the warrant, Andrew Porter showed up unexpectedly.

Officers watched him:

• Pull up to the house

• Exit his vehicle

• Carry a backpack, duffel bag, and blanket

• Walk inside with a dog

About 40 minutes later, officers executed the warrant. Inside:

• Porter was in the living room

• His backpack was in the corner, not on him

• Officers detained him and others

During questioning:

• Porter denied owning or knowing about the backpack

• Even after officers said they saw him carry it in, he stuck with the denial

Officers searched the backpack and found:

• ~78 grams of methamphetamine

• Marijuana

• Drug paraphernalia

Porter was charged and moved to suppress, arguing the search violated the Fourth Amendment.

Issues

1. Does a premises search warrant allow officers to search a visitor’s backpack found inside the home?

2. Does it matter that the backpack belongs to someone not named in the warrant?

3. Does denying ownership affect Fourth Amendment protections?

Court’s Decision (Holding)

The Iowa Supreme Court affirmed the denial of the motion to suppress.

• The backpack search was within the scope of the premises warrant

• No separate warrant or probable cause was needed

• Porter’s denial of ownership further undermined any privacy claim

Reasoning

1. This Was NOT a Warrantless Search Case

The biggest move in this opinion: the court said everyone was asking the wrong question.

The parties argued:

Did Porter have a reasonable expectation of privacy?

The court said:

Wrong question.

Because officers already had a warrant, the real issue was: Was the backpack within the scope of that warrant?

That shift drives the entire case.

2. Premises Warrants Are Broad

The court leaned heavily on United States v. Ross:

If officers have a warrant for a place, they can search any container that could hold the items listed in the warrant

That includes:

• Closets

• Drawers

• Boxes

• Bags

• Backpacks

The reasoning: The warrant targets the location, not specific people

So if drugs could be hidden in a backpack… The backpack is fair game.

3. The Key Rule: Physical Possession Matters

Here’s the bright-line rule the court adopted:

• If the item is on the person (worn, held, carried) → NOT searchable under the warrant

• If the item is not in physical possession → searchable as part of the premises

The court tied this to Ybarra v. Illinois, which protects people (and items attached to them), but not loose containers on scene.

In this case:

• The backpack was in the corner

• Not in Porter’s hands

• Not being worn

So it was treated like any other container in the house

4. Ownership Does NOT Control

The court made this clear:

It doesn’t matter who owns the container

What matters:

• Is it on the premises?

• Could it hold the evidence?

If yes → searchable.

This is huge for real-world policing: Officers do NOT have to stop and figure out ownership before searching containers

5. Denying Ownership = Big Problem for the Defense

Even though the court didn’t need abandonment to decide the case, it added:

• Porter repeatedly denied the backpack was his

• Courts routinely treat that as abandonment

Meaning: You can’t deny ownership and later claim privacy

6. Iowa Rejects Its Own Prior Approach (Sort Of)

The defense relied on an earlier Iowa case (State v. Brown) that protected a visitor’s purse.

The court basically said:

• That case was wrongly framed

• It confused warrant scope with warrantless search rules

And distinguished it because:

• In Brown, the purse was essentially on the person

• Here, the backpack was not

Street Takeaways (for Officers)

• Premises warrants are powerful

  • If it can hold the evidence → you can search it

• Physical possession is everything

  • In their hands/on their body = STOP

  • Sitting on the floor = GO

• You don’t need to determine ownership

  • Focus on location + capability, not who it belongs to

• Watch what suspects say

  • Denying ownership can eliminate their privacy claim

• Document everything

  • Where the item was located

  • Whether it was being held or worn

  • Statements denying ownership

• Ybarra still matters

  • You cannot search people just because they’re present

  • But their unattended property is a different story
