The same way they always did before DNA evidence became available about thirty years ago. They use other evidence - eyewitnesses, victims identifications of her attacker, hair and fiber evidence. Unless DNA samples on record match DNA taken from the victim the police must still use investigative techniques to identify suspects, so they would proceed in exactly the same way, just without the certainty that DNA provides when a suspect is found.
Addendum:It is important to note the instructions given to juries by most judges at trials for crimes with a sexual component. With a few minor differences those instructions are:"This is the only crime which requires no victim, no witnesses, no evidence, no testimony; if you the jury believes the defendant is guilty, he is guilty."
Doubting that, you should really attend a few trials.

When and where was the analysis of DNA first used to solve a crime?
The first time DNA analysis was used to solve a crime was in the United Kingdom in 1986. The case involved the rape and murder of two schoolgirls, and DNA evidence was crucial in linking the perpetrator to the crime scene. This landmark case led to the establishment of DNA databases for criminal investigations.
When was the first time DNA was used to solve a crime?
The first time DNA was used to solve a crime was in 1987 21 years ago, at Ventura's Top Hat Restaurant (which is now closed) in a murder that happened on the propterty
A piece of evidence that helps solve a problem?
DNA evidence found at a crime scene can help solve a criminal investigation by linking the suspect to the scene of the crime.
How is DNA fingerprints used to solve crimes?
DNA fingerprints are used in forensic investigations to link suspects to a crime scene or to eliminate suspects. By comparing the unique patterns of DNA found at a crime scene to those of potential suspects, forensic analysts can establish if there is a match, helping to identify or rule out individuals involved in the crime. This scientific method provides strong evidence for solving crimes and is a valuable tool in the criminal justice system.
How can lip print use to solve a crime?
There are actually two ways a lip print may be used to solve a crime. The primary one would be through the DNA left in the lip print itself. The other would be through "lip print identification" which means that our lip's are just as unique as our fingerprints and can easily separate one person from another. Thus, lip prints can be used to solve a crime.
How can foresice scientists use DNA in a crime?
Forensic scientists can use DNA in a crime by collecting DNA samples from the crime scene, comparing them to DNA samples from suspects to identify potential matches, and ultimately using DNA evidence to help establish the presence of a specific individual at the scene of the crime. DNA analysis can also be used to exclude suspects or link different crime scenes together based on DNA profiles.
What are the benefits to using DNA to solve crimes?
The DNA of each individual is unique. No two individuals share the same genetic make up unless they are identical twins. Analyzing DNA samples found at a crime scene can help place a suspect at the crime scene. If it can be legally proven that a suspect was present at a crime scene, there is practically no refutation to this finding. DNA test data is very valuable in court. But if you were never at the scene of the crime how can they prove you were anyone could have put it there?
What is the name of the job where you take DNA of a crime scene?
The name of the job where you would take DNA from a crime scene is called a Crime Scene Investigator.
How do the police solve a crime today?
If the crime happens in front of them they arrest immediately. If not, it is done by means of investigation.
What are the benefits and the limitations to using DNA to solve crimes?
Benefits of using DNA in solving crimes include highly accurate identification of suspects, cold case resolutions, and exclusion of innocent individuals. Limitations include potential contamination issues, the need for high-quality samples, and privacy concerns.
If DNA helps solve crime why isn't every crime solved?
No. DNA evidence can be challenged. It stills requires the ability to use the information provided by the DNA. Lying on the street, beneath the murdered man is a cigarette butt. It has YOUR DNA on it. Therefore, YOU must be the killer! Or just the person that tossed away a cigarette butt on that street 8 hours before the killer (who only smokes cigars) did the deed. PS- Identical twins also have identical DNA.
How does DNA help in solving crime?
Police and other crime investigation workers can take DNA from the scene of the murder (or other crime) and check it with databases of other DNA samples and match it to a person(s) and then they have their suspect(s).
