Yes, eventually they are found. Each time a criminal commits a crime he/she leaves behind a crimescene which contains evidence. It is impossible to not leave any forensic material behind, however often times the material left turns out to be unusable even with the technology we have today. Even if a criminal wrapped his whole body up in a big rubber condom-like thing, evidence left behind such as latex dust can very possibly be traced bach to the manufacturer, the lot, then the order, and so forth.
The proplem with serial murerers is that the more often an individual commits these crimes, the more evidence he adds to the case against him. Investigators use the evidence to link these crimes and then compile all of the clues into one case folder, from which eventually, they can write a book on the offender.
The #1 cause of a serial murderer being captured however, is that often they run their mouths and there are very few people who can actually keep secrets. I would say that 70% of the cases I have studied resulted in the capture of the criminal because he/she told someone, or incriminated themselves to the authorities when questioned, when in reality, there was no way that the evidence found at that point could have supported the prosecution's case against them.

Unfortunately serial killers are the hardest ones to catch. Usually because they kill without a conscience. As technology gets better, so does forensic evidence. Serial killers always make a mistake and eventually will be caught.

Forensics can only go so far. DNA can identify someone for instnce only if that person's DNA is on record. Even then it is a huge data search. Fingerprints helped but were also limited by things like gloves and smearing. Even DNA evidence can be tampered with and end up unuseable.

Only if there is no record of their DNA anywhere on file. One cannot force one to give up their DNA without just cause or even suspicion.

Sure, not all are caught by DNA evidence, and besides, in order to use DNA evidence, you have to have something to compare it to.

Yes, it is entirely possible. The majority of murders go unsolved every year.
