What Happens When Someone Calls the Police for Domestic Violence in Missouri?

When someone calls 911 and reports domestic violence in Missouri, a specific legal process begins that often cannot be stopped, even if the caller regrets making the call.

Many people are shocked to learn that once police arrive, the alleged victim’s wishes become largely irrelevant. Officers will make arrests based on probable cause, and prosecutors will file charges regardless of whether the alleged victim wants to cooperate. Once that call is made, the criminal justice system takes control.

At Rose Legal Services, we dedicate our practice exclusively to criminal defense. We’ve represented hundreds of clients in domestic violence cases throughout Missouri, and we understand how quickly these situations can spiral. Here’s what happens after that 911 call, and why contacting an attorney immediately can make all the difference.

What Happens When Police Respond to a Domestic Violence Call

The moment someone calls 911 and reports domestic violence, a specific legal process begins that often can’t be stopped — even if the caller immediately regrets the call.

Mandatory Response Policies

Law enforcement agencies throughout Missouri take domestic violence calls seriously. When officers receive a domestic violence call, they respond quickly and arrive prepared to make an arrest. Many jurisdictions have mandatory arrest policies, meaning officers must arrest someone if they have probable cause to believe domestic violence occurred — regardless of what the parties want.

What Officers Look For

When police arrive after a domestic violence call, they typically separate everyone present to get individual statements, look for visible injuries on both parties, and photograph any injuries, no matter how minor. Officers examine the scene for signs of a struggle, talk to any witnesses (including children or neighbors), and document everything in their police report.

Officers are trained to look beyond what people tell them. They observe body language, emotional states, the condition of the home, and any physical evidence of an altercation.

The Primary Physical Aggressor Determination

Missouri law requires officers to determine who was the “primary physical aggressor” in domestic violence situations. This doesn’t simply mean who threw the first punch or who has visible injuries. Under Section 455.085 of the Revised Statutes of Missouri, the term “primary physical aggressor” is defined as the most significant, rather than the first, aggressor. Law enforcement is required to consider:

• The intent of the law to protect victims from continuing domestic violence
• The comparative extent of injuries inflicted or serious threats creating fear of physical injury
• The history of domestic violence between the persons involved

In practice, officers often also consider who was the initial aggressor, whether anyone acted in self-defense, who appears to be in fear, and the relative size and strength of the parties.

This determination decides who gets arrested.

A Person Can Be Arrested Even If The Alleged Victim Doesn’t Want To “Press Charges”

Many people are shocked to learn that once police are called, the alleged victim’s wishes become largely irrelevant. Even if the alleged victim says, “I don’t want to press charges,” or “I didn’t mean for this to happen,” officers will make an arrest if they believe probable cause exists that domestic assault occurred.

This is because domestic violence is considered a crime against the state, not just against an intimate partner or family member. The criminal justice system has taken control of the situation.

What Happens After an Arrest for Domestic Violence

When a person is arrested for domestic assault in Missouri, he or she is transported to jail, booked, fingerprinted, and photographed. In most circumstances, the person will be released in a few hours. If the charge is a misdemeanor, he or she will likely be released with a citation and a court date, or sometimes the citation will say “To Be Notified” as the court date. Otherwise, law enforcement may release the suspect “pending application of warrant,” which means that law enforcement will submit the charges to state prosecutors to consider felony charges. Law enforcement is required to release anyone they have arrested within 24 hours unless they obtain a warrant, which happens in only the most serious cases.

How Domestic Violence Charges Are Actually Filed

Here’s what many people don’t understand: the alleged victim doesn’t “press charges,” the prosecutor does.

The Prosecutor’s Decision

After the arrest and after police have completed their investigation, the police report goes to the prosecutor’s office. A prosecutor, not the alleged victim, decides whether to file formal charges and what degree of domestic assault to charge. This decision is based on:

• The police report and officer observations
• Photographs of injuries
• Witness statements
• The prosecutor’s policies and priorities

The alleged victim can tell the prosecutor they don’t want charges filed, but in the St. Louis area, prosecutors generally proceed anyway. Every prosecutor’s office we deal with in the area has what is called a “no drop” policy on these types of cases — meaning they will file the cases (if they believe the evidence warrants it) and they will prosecute them, even if the alleged victim requests otherwise.

Understanding Missouri’s Domestic Assault Degrees and Penalties

Missouri law defines four degrees of domestic assault with escalating severity:

Domestic Assault in the First Degree (RSMo § 565.072) — Under Missouri law, “a person commits the offense of domestic assault in the first degree if he or she attempts to kill or knowingly causes or attempts to cause serious physical injury to a domestic victim, as the term ‘domestic victim’ is defined under section 565.002.”

“The offense of domestic assault in the first degree is a class B felony unless in the course thereof the person inflicts serious physical injury on the victim, in which case it is a class A felony.”

Domestic Assault in the Second Degree (RSMo § 565.073) — Under Missouri law, “a person commits the offense of domestic assault in the second degree if the act involves a domestic victim, as the term ‘domestic victim’ is defined under section 565.002, and he or she:

(1) Knowingly causes physical injury to such domestic victim by any means, including but not limited to, use of a deadly weapon or dangerous instrument, or by choking or strangulation; or

(2) Recklessly causes serious physical injury to such domestic victim; or

(3) Recklessly causes physical injury to such domestic victim by means of any deadly weapon.”

“The offense of domestic assault in the second degree is a class D felony,” carrying up to seven years in prison.

Domestic Assault in the Third Degree (RSMo § 565.074) — Under Missouri law, “a person commits the offense of domestic assault in the third degree if he or she attempts to cause physical injury or knowingly causes physical pain or illness to a domestic victim, as the term ‘domestic victim’ is defined under section 565.002.”

“The offense of domestic assault in the third degree is a class E felony,” punishable by up to four years in prison.

Domestic Assault in the Fourth Degree (RSMo § 565.076) — Under Missouri law, “a person commits the offense of domestic assault in the fourth degree if the act involves a domestic victim, as the term ‘domestic victim’ is defined under section 565.002, and:

(1) The person attempts to cause or recklessly causes physical injury, physical pain, or illness to such domestic victim;

(2) With criminal negligence the person causes physical injury to such domestic victim by means of a deadly weapon or dangerous instrument;

(3) The person purposely places such domestic victim in apprehension of immediate physical injury by any means;

(4) The person recklessly engages in conduct which creates a substantial risk of death or serious physical injury to such domestic victim;

(5) The person knowingly causes physical contact with such domestic victim knowing he or she will regard the contact as offensive; or

(6) The person knowingly attempts to cause or causes the isolation of such domestic victim by unreasonably and substantially restricting or limiting his or her access to other persons, telecommunication devices or transportation for the purpose of isolation.”

“The offense of domestic assault in the fourth degree is a class A misdemeanor,” for first offenses, but becomes a Class E felony for those with prior assault convictions under RSMo § 565.079.

The prosecutor decides which degree to charge based on the severity of injuries, the circumstances of the incident, and the defendant’s criminal history.

Can the Alleged Victim Drop the Charges?

This is the most common question we hear, and the answer is: no.

Once charges are filed, the case belongs to the State of Missouri or whatever governmental entity is prosecuting it. The alleged victim may be a witness, but he or she is not a party.

Why Prosecutors Proceed Without Victim Cooperation

Prosecutors continue with domestic violence cases even when the alleged victim doesn’t want to participate because:

• They believe domestic violence victims often face pressure to recant
• They view these cases as important for public safety
• They have evidence beyond the victim’s testimony (police observations, photos, 911 recordings)
• They want to prevent future violence

However, cases become much harder to prove when the alleged victim won’t cooperate. An experienced attorney knows how to leverage this to a defendant’s advantage.

Common Scenarios in Missouri Domestic Violence Cases

Domestic violence cases are rarely as straightforward as they appear in the initial police report.

Mutual Combat Situations

Many domestic violence arrests occur after both parties were involved in a physical altercation. One person gets arrested based on the primary physical aggressor determination, but the reality is more complex. Officers arriving during a heated moment must make quick decisions, and those decisions aren’t always accurate.

Self-Defense

The defendant may have been defending himself or herself when the police were called. Missouri law recognizes the right to self-defense under RSMo § 563.031, but self-defense is a defense that must be asserted in court. An attorney can present evidence that a person acted in self-defense.

False Accusations

During contentious divorces or custody battles, some people make false domestic violence allegations to gain an advantage in family court. False accusations are more common than many people realize, and they can devastate the accused person’s life, affecting custody, employment, and reputation.

An experienced attorney knows how to investigate these situations, expose inconsistencies, and present evidence of ulterior motives.

Mental Health and Substance Abuse

Domestic disputes often involve complex issues like mental health conditions, substance abuse, or escalating arguments that got out of control. These factors don’t excuse violence, but they provide important context that affects how cases should be resolved.

Other Reasons People Call the Police

Prosecutors’ “no drop” policy in these cases fails to recognize that people in conflict often have reasons for calling the police other than the intention to seek someone’s arrest and prosecution. Often, they are just looking for help to break it up and “restore the peace” for substance abuse issues, for mental health reasons, or other reasons. And often the decision to call 911 was a panic response, not the product of careful deliberation.

Why Immediate Legal Representation Matters in Domestic Assault Cases

If someone calls the police and a person is arrested for domestic assault, contacting an experienced criminal defense attorney immediately is essential.

An Attorney Can Protect Constitutional Rights From the Start

The moment someone is arrested, that person has constitutional rights that need protection:

• The right to remain silent under the Fifth Amendment
• The right to an attorney under the Sixth Amendment
• Protection against illegal searches under the Fourth Amendment
• The right to challenge evidence

Many people unknowingly waive these rights by talking to police or making statements that hurt their case.

An Attorney Can Negotiate Better Bond Conditions

Having an attorney at a bond hearing dramatically improves the chances of:

• Lower bond amounts
• Release on one’s own recognizance
• Modified no-contact orders that allow limited communication about children or property
• Conditions that allow a person to return home

An Attorney Can Build a Defense Early

The earlier an attorney begins working on a case, the better:

• Interviewing witnesses while memories are fresh
• Gathering evidence that supports the defendant’s version of events
• Identifying weaknesses in the prosecution’s case
• Documenting injuries or lack of injuries
• Obtaining medical records, phone records, or other evidence

An Attorney Can Negotiate With Prosecutors

Experienced criminal defense attorneys have relationships with prosecutors and know how to negotiate effectively. We can:

• Present mitigating evidence
• Demonstrate weaknesses in the state’s case
• Negotiate for reduced charges or dismissal
• Explore diversion programs or alternative resolutions
• Keep someone out of jail and minimize the impact on their life
