Why are many people unwilling to provide tips to police that could solve a murder?

Jobo - Yes,  it is very odd that law enforcement were  not taking finger prints along with dna.  Perhaps they felt that dna would be the end all and be all - and finger printing would take just as long to verify?  Or is asking for finger prints totally illegal, unless charged, but it is okay to ask for dna voluntarily?

I would sure like to know the answer.

Or - he wore gloves.

ps, I found this: 

and quote
Members of the AFIS section also manually compare crime scene fingerprints with those of suspects submitted by the investigative units and squads.
We don't know if the Police got prints from the car...but one would think there should've been prints unless the perp wore gloves.....Sonia's dad had washed the car that day.
Also, I watched a show where they sent the item to a lab in Toronto that can determine prints on material ( using gold and zinc)....makes me wonder if Police sent anything of Sonia's to that lab.
If in fact the perp did wear gloves, then he certainly came prepared to do what he did.
Thanks SAP. Good catch!! The article is clear and concise.  That is what I was looking for ... although I think I called it phototyping.  lol. It has been used with some success in Holland.
According to the article,  it cannot determine height of the individual.

Height can be determined by shoe size, according to the following article from Forensic Magazine

The height of an individual can be determined by his/her footprint and shoeprint. The foot tends to be approximately 15% of the personís average height. At times series of footprints are left at the scene of a crime forming a recognizable gait cycle. [quote/].

When will it be used in Canada?  Our Charter of Rights and Freedoms - may not allow it in court - but could it be used as a guide for detectives?  It is better than a composite drawing -  and they are used all of the time.

This Sheriff got up on the wrong side of the bed. It could happen to anyone and it's dang scary.



Reston, Va.-based Parabon Nanolabs, with funding from the Department of Defense, has debuted a breakthrough type of analysis called DNA phenotyping which the company says can predict a person's physical appearance from the tiniest DNA samples, like a speck of blood or strand of hair.

The DNA phenotyping service, commercially known as "Snapshot," could put a face on millions of unsolved cases, including international ones, and generate investigative leads when the trail has gone cold.


Quote from above link:

"When labs try to "type" samples that CONTAIN TOO LITTLE DNA, or DNA that is too degraded, the results of the DNA test can be unreliable.

Labs try to make allowances for these distortions when dealing with LIMITED or degraded samples."


So, a limited DNA sample appears to be one that doesn't have enough DNA to produce a full profile of the killer.

Thanks for fixing my link jb.  I modified it.
I would assume a match was made to a very distant relative or some sameness of race.. Zeroing in process.... jmo

the link provided did not work.  I found another one dealing with the same story.  Here is an interesting conclusion in this article
  limited DNA match of a suspect has been yielded.

What did they mean by limited?  Was there partial dna only?  Any thoughts? /jb
In the latest video that was released showing the two unidentified males in the gazebo across from where Sonia's car was dropped off, it is twilight at best. Assumptions are that what caught their attention was the lights and activity related to Sonia's car pulling in. Generally speaking, anyone travelling with a body would usually want to dispose of the evidence asap and would not want to add to the risk by transferring or moving or keeping the body any longer than what was absolutely necessary.. 

But it is possible, we have no idea why Sonia's body was removed for what purpose or what was done afterwards.

The source of the dna found with Sonia could be anything, hair, skin, semen, blood, we arenít going to be told. But consider the location where she was found. A perp had to carry her body through a treed area in the dark. The potential for a perp to accidentally leave dna behind is increased.  Snagging hair on a branch or scraping against some tree trunk or object is a distinct possibility. We wonít be told but the difference between accidentally deposited dna and sexual or deliberately deposited dna goes to the heart of what the investigators are dealing with including motive. Consider no reports claim this dna was found elsewhere, not in Soniaís home, not in her freshly washed and cleaned car.

D1, are we sure her remains were left there immediately that night, in the dark?, they were not found immediately and I do not know if it is fact that the perp did so in the dark, 5 or 6am would have some day light, if her body was transferred to another car and taken else where, here remains could have been dropped off later? No?
