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.

What are the benefits and the limitations to using DNA to solve crimes?
The benefits of using DNA to solve crime are many. Every human has their own DNA which means that no matter how well someone tries to hide their identity, they can never change their DNA. This translates to being able to use DNA to track down a criminal or identify a victim's body. The limitations of the process are many though as DNA can wash away before it is collected.

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.
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?

Why is DNA important?
DNA is like the "blue prints" of a person. Almost everything that happens in your body is based on DNA. It could be used to identify people. It could be used to find out if someone is someone's child, parent or other relative. It is often used to solve crimes. A hair or blood found on the crime scene could match the DNA sample of a suspect who is claiming he's never been at the scene. It could also be used to find genetic diseases.
