When police suspect criminal activity, they investigate. This is called a pre-file. It precedes filing criminal charges.
During a pre-file, law enforcement may:
- Interview witnesses,
- Gather evidence,
- Search background records, and
- Hire independent experts
The District Attorney (D.A.) then decides whether to press charges. People who know they are under investigation should lawyer up as soon as possible. Defense attorneys conduct independent probes, which place suspects in a readier position if the D.A. prosecutes.1
Police detectives may phone or show up at suspects’ doorsteps. But often pre-files remains secret. Covert operations reduce the chances that suspects will flee or destroy evidence (NRS 199.220).
It varies case-to-case. Some can last months. This is not unusual in cases involving:
It depends. Sometimes police have insufficient probable cause to arrest a suspect. Therefore the police will conduct a pre-file investigation. If they gather adequate evidence, they will conduct an arrest, and the D.A. will file charges.
In other cases, an arrest is the start of a pre-file investigation. Getting arrested does not necessarily mean that the D.A. has enough evidence to press charges. Therefore whenever a suspect is arrested, the case typically goes into screening. This is when the D.A. examines (screens) the police reports to decide whether the case is strong enough to bring criminal charges. If there is not enough evidence, the D.A. will deny the case. This means no criminal charges will be brought.
In more serious or high-profile cases, police may have enough probable cause to arrest a suspect but will hold off on until they gather all available evidence through the investigation. This way the D.A. is confident from the beginning they have a strong case and can formally press charges shortly after the arrest.2
No. Never speak to police. People have the Constitutional right against-self-incrimination. This is the right to remain silent. And choosing to remain silent cannot be used against suspects in court.3
Meanwhile, giving damning statements to police can sink a defense. It is difficult to get statements or confessions excluded as evidence.
When people are being investigated for a crime, they are understandably eager to tell their side of the story to police. Suspects may feel that if they cooperate fully and answer questions, the investigation will go away. But that does not happen. Speaking to the police can only make matters worse.
Police are allowed to lie when they question suspects. They may employ sneaky interrogation tactics to elicit a confession. They may twist a suspect’s words around, act friendly to win a suspect’s confidence, or act like bullies to intimidate a suspect into talking. That is why suspects should remain silent and let their attorneys speak for them.
If the police call or knock, avoid answering. Otherwise, say you are exercising the Fifth Amendment and remain silent.
Absolutely. Anyone under investigation for committing a crime should hire an experienced attorney. That way, defense counsel can:
- Proactively conduct its own investigation.
- Hire its own scientific experts and detectives.
- Gather information.
- Serve as intermediary between the suspect and defectives.
- Demand that detectives stop contacting the suspect.
Yes. Criminal defense lawyers may discuss pre-file cases with prosecutors. This might persuade the D.A. to drop the charges or file less serious charges. But in some cases, contacting the D.A. early is not wise.
Thousands of cases swamp the D.A.’s office with some going unnoticed, especially misdemeanors. Contacting prosecutors about a case draws attention to it, so it may be best to wait and see what happens. Maybe the case will fall through the cracks, resulting in no charges.
Possibly. First your criminal attorneys will evaluate the exculpatory (favorable) evidence. Then they can approach the D.A. and argue that the state does not have sufficient evidence to sustain a conviction. The D.A. may then elect to drop the investigation.
But some prosecutors insist on bringing formal charges and forcing the matter to play out in court no matter what criminal lawyers do to dissuade them.
