Summary:
Toyah had Singh’s DNA under her fingernail at the time of her death.
DNA under a fingernail is not a place where DNA ends up casually. It’s most often the result of close, physical contact and usually due to a struggle.
The DNA evidence shows that male genetic material found under Toyah’s fingernail matched Singh almost perfectly.
Two separate tests were run and one showed 26 out of 27 Y-chromosome markers matching Singh, and the other showed all 27 matching.
Y-chromosome DNA is shared amongst paternal male relatives, so the DNA under Toyah’s fingernail can only belong to Singh or his father, brothers, or cousins.
Patel (the scientist) confirmed that the male DNA under Toyah’s fingernail is consistent with Singh’s genetic profile. It does not match Marco, or any other man tested.
Other partial tests also pointed to Singh.
DNA under the fingernail is pretty telling and the circumstances make Singh the most likely source.
