Found a Gun While Magnet Fishing? Here's What the Law Requires

Why Firearm Finds Are Legally Different from Everything Else

When you pull a bike frame or a shopping cart out of a river, you're dealing with junk. When you pull out a firearm, you may be in contact with evidence from a crime — and how you handle it from that moment forward has legal consequences regardless of your intent.

Guns end up in waterways for a handful of reasons: criminals dispose of them after use in crimes, they fall from boats or bridges, they're tossed by people cleaning out estates, or they're deliberately discarded by owners who don't know how to dispose of them legally. The problem is that from the outside, you cannot tell which category you've found. A rusted pistol pulled from a river could be a World War II-era relic, a family heirloom, a stolen weapon used in an unsolved homicide, or a functional firearm someone planned to retrieve.

The legal framework treats all of them the same way: as found property with potential criminal history that law enforcement has both the right and the obligation to examine.

Step-by-Step: What to Do Right Now

Step 1 — Stop. Don't touch it more than you already have.

If the gun is still on your magnet and hasn't been handled, that's ideal. If you've already picked it up, set it down carefully on a flat surface away from people. Do not attempt to unload it, check the chamber, or clear it. Waterlogged firearms can still fire — sometimes more easily than dry ones, depending on the mechanism. Do not operate any part of the action.

Step 2 — Call the non-emergency police line (not 911, unless you're in immediate danger)

In most situations, this is not a 911 call. Look up the non-emergency number for your local police department or county sheriff before you go magnet fishing — it should be saved in your phone. Tell them: (1) you found a firearm while magnet fishing, (2) your exact location, and (3) that the firearm is secured and you are waiting for an officer.

If you're in a remote area without a clear jurisdictional authority, call your state police dispatch. They can route the call appropriately.

Step 3 — Document the location and find

While you wait, take a photo of the firearm where it landed — on your magnet, on the ground, or wherever it is — and note the GPS coordinates or address. Do not post these photos publicly yet. This documentation protects you by establishing the chain of custody and your version of events from the moment of recovery.

Step 4 — Turn it over to the responding officer

When law enforcement arrives, hand over the firearm — along with your documentation — and provide a brief, factual account of what happened. You do not need a lawyer present for this interaction in most cases. You found a firearm, you called it in, you're turning it over. That's the right sequence of events and officers recognize it as such.

Step 5 — Get a receipt or case number

Ask the officer for a case number or a receipt for the firearm. This is your documentation that you surrendered the item to law enforcement — which matters if questions arise later about the weapon's whereabouts. Most departments will provide this automatically, but ask if they don't.

What You Cannot Legally Do

Several courses of action that might seem intuitive are legally problematic:

• Taking it home: Transporting a found firearm — even with good intentions — can violate state laws on unlawful possession of a firearm, particularly if the weapon turns out to be reported stolen or has had its serial number altered. In some states, transporting a found gun without immediately notifying police is itself a crime.
• Cleaning or restoring it: Cleaning a firearm removes ballistic evidence. If that weapon was used in a crime, you've just destroyed evidence. This can expose you to obstruction charges in some jurisdictions even if you had no knowledge of any prior crime.
• Posting it on social media first: Photographing and posting a found firearm before contacting law enforcement is legal in most places, but it has caused significant problems for magnet fishers. Officers have noted that public posts showing found guns have, in several documented cases, alerted suspects that the weapon was recovered — compromising active investigations. Handle the legal steps first.
• Selling it: Selling a found firearm is illegal in virtually every U.S. jurisdiction regardless of the seller's knowledge of its history.
• Keeping it as a "trophy" or wall display: A found firearm is found property, not yours by legal right in most states. State abandoned property laws typically require either reporting or surrender to law enforcement.

State-by-State Variation: What You Should Know

While the general protocol above applies nationwide, some states have specific provisions worth knowing:

• Texas: Texas Penal Code § 46.06 makes it illegal to transfer a firearm to a person you know or have cause to believe intends to use it unlawfully. More relevant: Texas's found property statute (Property Code § 72.001) applies to found firearms and requires reporting to local law enforcement within a reasonable time.
• Florida: Florida Statute § 790.065 and related provisions make transporting a found firearm without notifying law enforcement potentially problematic under "constructive possession" doctrine. Florida law enforcement has been particularly active in prosecuting magnet fishers who transported firearms without reporting.
• California: California Penal Code § 25400 (carrying a concealed firearm) and § 26350 (openly carrying an unloaded handgun) both apply to found firearms in transit. California has among the strictest standards — call law enforcement before the gun leaves the waterway bank.
• New York: New York's SAFE Act and Penal Law § 265.01 create significant exposure for anyone in possession of a firearm without a license, including found firearms. Report immediately and do not transport without explicit police instruction.

What Happens to the Gun After You Turn It Over?

Law enforcement will run the serial number through NCIC (the FBI's National Crime Information Center) to check for theft or crime-scene reports. If it's stolen, it becomes evidence in that case. If it's not stolen, it may be held as found property for a period before being either returned to a documented owner, destroyed, or (in some states) auctioned after the holding period. You will generally not receive the firearm back.

In rare cases where a firearm is determined to be a historical or collector's item of significant value, some states have provisions for the finder to make a claim — but this is the exception, not the rule, and requires going through a formal legal process.

Can You Keep a Found Gun?

In almost all U.S. jurisdictions, no. Found property law in most states requires reporting found property of value to law enforcement. Firearms are specifically addressed by gun laws that effectively prohibit private retention without going through a licensed dealer and background check. If a firearm has been legally abandoned (which requires documentation that no owner exists and the holding period has elapsed), a handful of states allow finders to claim it through a formal process — but this requires engaging with law enforcement, not bypassing them.
