Would a profiler be able to help predict where a certain POI would hide or dispose of a body? I believe they need to find Heather.
WideOpen, geographic profilers/profiling is used for predicting the likely distances and areas of body disposal as well as other geographical info..

Could a profiler also be used to try to predict the behavior of a perp?
I wouldn't be surprised if a profiler also suggested psychological ways to question a particular suspect to try and get the subject to confess.
I think one job of a profiler would be creating a list of characteristics about Heather's killer, and releasing them to the public. That seems like something they would do when they think a stranger is responsible, but don't have a suspect. So people call in about those who fit the description, and LE can test their DNA, etc.
I am not sure if a profiler could rule out SM, especially if they have evidence and a motive and no alibi, etc. Or even rule him in, if they don't have the necessary evidence. I really have no idea how well the profile would stand up in court. It seems like it's done to find possible suspects, who LE can then investigate, rather than used to convict someone.
John Douglas profiled R. Hansen to a tee. He had pegged him with a studder or lisp, bad complexion, as an independent business owner, church going with a family. Hansen owned a bake shop where LE frequented(pastries) and was a pillar of the community. Although a suspect in the murder of many prostitutes, Hansen convinced investigators that it was all a misunderstanding.
Hansen's personal info wasn't made available to John Douglas or Roy Hazelwood, until the preliminary unsub profile was complete.

After reading an article in Psychology Today about the BSU and criminal profiling, the FBI BSU/BAU was contacted by the Alaskan State Trooper Detective Glenn Flothe, requesting assistance after being denied a search warrant by a judge, for lack of probable cause. Detective Flothe began telling FBI Profiler Roy Hazelwood about Robert Hansen.
Hazelwood said, "No, No, No"! Detective Flothe was advised by Hazelwood, not to give information pertaining to the suspect, only the victims and the specifics of the investigation.(An Artist is revealed by reviewing his Artwork)...
In the A & E documentary Detective Flothe states that John Douglas and Roy Hazelwood profiled Robert Hansen, and Douglas stipulated that the suspect would most likely have a lisp and have low self esteem, among other characteristics...
Criminal Behavior Profiling is not based on lucky guesses, but many years of research, interviews on many Serial Killers prior, crime scene analysis, deductive reasoning, common sense, as well as the ability to peel away the mask of normalcy and enter the darkness of the minds of those beyond evil...

FYI: John Douglas, predicted to the day that Atlanta, GA: Child Serial Killer Wayne Williams, would fake a medical emergency to gain sympathy from the jury during his trial. Williams complained of chest pains and was rushed to Grady Hospital, where Doctors found no signs of a heart condition...
John Douglas, advised Prosecutor Myers, in the Larry Gene Bell, Death Penalty Trial, Lexington Co., SC, for the Murder of Sherry Faye Smith, that Bell would cause an outburst or disturbance in the courtroom on the first day.
To the Prosecutors amazement, Bell acted out Douglas's prediction...
Bell was executed in 1996....
