Takoradi, Ghana – The Lead Medical Doctor of the forensic team put in charge of DNA analysis on the supposed skeletal remains of the 4 Takoradi Girls who went missing, Supt. Dr. Kofi Agyapong Afrifa has confirmed that analysis of the remains found points to the fact that they indeed belong to the missing girls.
His confirmation of the findings comes after lawyers of the two suspects that have been accused of carrying out the murder the girls expressed doubts on the DNA conclusion of the Police report.
The Lead Doctor said that the concluding part of their findings proved that there is a genetic linkage between the remains found and that of the parents of the victims.

And for the Abekah family, we found out that Cecilia Owusu who is the alleged mother of missing Ruth Abekah shares common allele with Skull 3 at all loci tested. The probability of stated relationship which is the Combined Maternity Index (CMI) is 202552413.7053 and probability of maternity is 99.99 percent” he said.
