If you or a family member was just arrested, or notified of charges involving an assault and a weapon, you probably have one urgent question: what happens now?
The short answer: an arrest sets a process in motion that moves quickly. After booking, a judge will make a bond determination, formal charges will be filed, and the case moves through evidence review, potential negotiations, pretrial motions, and possibly trial. How that unfolds depends entirely on the specific facts, the court, and the people involved.
What this article can do is help you understand what to expect and what to do next. What it cannot do is tell you what charge applies to your situation, what sentence you face, or what defense strategy makes sense, that requires a review of your actual documents and facts by a qualified Missouri criminal defense attorney.
How Missouri Classifies Assault Allegations Involving a Weapon
Missouri does not have a single charge simply called “assault with a dangerous weapon.” Assault charges are organized by degree, and the specific charge filed in any case depends on a combination of factors:
- The alleged intent of the person charged
- The severity of injury alleged
- The nature of the weapon or instrument involved
- The identity of the alleged victim
- Other circumstances prosecutors consider relevant
Missouri’s second-degree assault statute, for example, includes attempting to cause or knowingly causing physical injury by means of a deadly weapon or dangerous instrument, but that is not the only charge possible in a weapon-related case. Allegations involving more serious injury, firearms, protected classes of victims, or specific circumstances can result in higher-degree charges, additional counts, or both.
The point is this: a weapon allegation does not mean every case is charged the same way. The facts matter, and so does having an attorney who understands how prosecutors in your jurisdiction approach these cases.
What Counts as a Deadly Weapon or Dangerous Instrument?
Missouri law distinguishes between these two terms, and context matters significantly in how they are applied.
An object may be evaluated based on what it is and how it was allegedly used. Objects that may be analyzed as deadly weapons or dangerous instruments include:
- Firearms
- Certain knives
- Bats or blunt objects
- Bottles or tools
- Vehicles, in certain alleged circumstances
This is not a simple checklist. Whether a specific object qualifies in a specific case depends on the alleged facts, how the object was used, and what injury or threat of injury resulted. An attorney reviewing your case can assess how these arguments apply to the actual evidence.
What Happens After an Assault Arrest in Missouri?
The process following an arrest generally follows a sequence, though county practices, case circumstances, and court procedures can affect the timing and exact steps.
Step 1: Booking and Custody
After arrest, you are processed at a detention facility, photographed, fingerprinted, and held pending a bond hearing. Personal property may be held by law enforcement during this time.
Step 2: Bond Determination
A judge decides whether you can be released and under what conditions. Factors that typically influence this include:
- The severity of the alleged offense
- Whether a weapon was allegedly involved
- Prior criminal history
- Ties to the community
There is no guaranteed bond amount, no automatic release, and no universal timeline. Bond decisions are made case by case.
Step 3: Arraignment
This is the formal hearing where you are informed of the filed charges and enter a plea. It is not a trial, and it is not where detailed defenses are presented, but it is a significant procedural step, and having an attorney present matters.
Step 4: Everything That Follows
After formal charges are filed, the case typically moves through:
- Discovery: The prosecution shares its evidence with the defense
- Pretrial motions: Challenging evidence, constitutional issues, or procedural problems
- Negotiations: Potential resolution without going to trial
- Trial, if the case does not resolve through other means
Not every case goes to trial and not every case is resolved through a plea. The path a case takes depends on the facts, the evidence, and the strategy developed with your attorney.
Bond Conditions and No-Contact Orders
Being released on bond does not mean the legal process is over, and release comes with rules that must be followed.
Common conditions in weapon-related assault cases include:
- No contact with the alleged victim
- Geographic restrictions
- Prohibition on possessing firearms or weapons
- Electronic monitoring
- Substance restrictions or testing requirements
Bond conditions are court orders. Violating them, even accidentally, even at the other party’s request, can result in immediate return to custody and additional legal consequences.
Do not contact the alleged victim to work things out, ask them to reconsider, or discuss the allegations, even if they reach out to you first. Even well-intentioned contact can create new legal exposure on top of your existing charge. If you are unsure what your conditions require, ask your attorney before taking any action.
This is especially important in cases where the alleged victim is a family member, partner, roommate, or acquaintance, situations where a no-contact order can directly affect living arrangements and daily life.
Why the First Few Days Can Matter
The period immediately after an arrest can be consequential for how a defense is eventually built. A few reasons:
- Surveillance footage from businesses or nearby cameras may be overwritten on short retention cycles
- Witness recollections are typically most detailed closest to the event in question
- Law enforcement may seek a statement, and you have the right to speak with an attorney before responding to any request
A defense lawyer can assess whether evidence should be preserved or reviewed and whether any steps are time-sensitive to your case.
Never delete, alter, or destroy any evidence, messages, or digital data related to an investigation, regardless of what it contains. Doing so can result in serious additional legal consequences entirely separate from the underlying charge.
What Should You Do Right Now?
If you have been arrested, charged, or approached by investigators, here are the steps to take immediately:
- Keep all paperwork, every document related to your arrest, bond, court notices, and charging documents
- Follow every bond condition without exception, including no-contact orders, firearm restrictions, and reporting requirements
- Attend every scheduled hearing, missing a court date can result in a warrant for your arrest and additional consequences
- Do not speak with police or investigators about the facts of your case without first consulting an attorney, this is your legal right and using it is not an admission of guilt
- Do not contact the alleged victim or any witnesses if restrictions apply or if doing so could create additional legal issues
- Contact a Missouri criminal defense attorney as soon as possible, earlier involvement means more options
