Many times when a crime victim is set on fire, it is not personal and may not be due to rage, revenge, or for any other reason except to destroy forensics evidence.. Chalk it up to the CSI affect.. Imo, the person/s responsible for JC's senseless murder will have a very long rap sheet consisting of many misdemeanors since adolescence, as well as the probability of a past felony indictment, imo..
The heinous nature of this crime, the refusal of investigators to release the autopsy results<silence>, and the sudden involvement by the FBI indicates the likelyhood of a sexual predator/serial killer involvement, imo.

What is a Familial Search?
As a result of the growing number of DNA profiles stored in DNA databases worldwide, a controversial technology has emerged onto the forensic scene. Criminals whose DNA profile has never been entered into a DNA database because they were never arrested, prosecuted or convicted of a crime can still be identified through a technique called familial searches.
Today, your DNA kinship can be sufficient to link you to a crime.
"Familial searching is a technique whereby a crime scene profile is deliberately run through the offender databank in the hopes of getting a list of profiles that are genetically similar to the DNA evidence and using this information as an investigative lead to interview family members of the near matches."
When a DNA profile is obtained from a crime scene and that profile is passed through the FBI's electronic program, the Combined DNA Index System (CODIS). A perfect hit will be obtained if all 26 alleles match a DNA profile in the database, indicating that the DNA sample is from the same person. But if a partial match occurs on at least 15 or more alleles then this could indicate that a close relative left the sample at the crime scene. A relative whose past conviction or arrest required them to provide their DNA can now send another family member to prison.

The United States and Familial Searches
As of January 2010, the FBI's National DNA Index System (CODIS) contains over 7.8 million DNA profiles of offenders and over 300,000 forensic profiles, making it the largest DNA database in the world. (Compared to the British system that has more than 5% of its citizens in its DNA database including 800,000 innocent people, the U.S. has only 0.5% of the American population.) CODIS has produced over 101,000 hits and assisted in more than 100,000 investigations. One can follow the statistics of CODIS at the FBI CODIS website. The website tracks the number of offenders added to the DNA Database of each state and also follows the number of "Investigations Aided" where CODIS has added value to the investigative process.
Following the success of familial searches in the U.K., two major studies brought the issue of familial searches to the forefront in the U.S.
In 2004, the U.S. Justice Department published a report that concluded that almost half (48%) of all prison inmates surveyed reported having a close relative who had also been imprisoned. Usually this was a sibling, primarily a brother.
