KOH TAO – Pol Gen Somyot Phunphanmuang disclosed the latest test of DNA samples collected from semen found inside the body of Ms Hannah Witheridge, 23, showed they belonged to Mongoloid people or Asians.
He revealed the finding just before boarding a flight to Surat Thani today to direct the investigation and hunting down the suspects.
The latest discovery has now enabled the police to narrow their investigation to focus on specific groups, migrant workers and local Thai people.
Pol Gen Somyot also said the Royal Thai Police has now suspended its earlier plan to seek help from the Federal Bureau of Investigation (FBI) after forensic doctors could conduct deeper test of the Y chromosome DNA test.
A Y chromosome DNA test (Y-DNA test) is a genealogical DNA test which is used to explore a man’s patrilineal or direct father’s-line ancestry.
The genealogical DNA test looks at a person’s genome at specific locations. Results give information about genealogy or personal ancestry. In general, these tests compare the results of an individual to others from the same lineage or to current and historic ethnic groups.
