Ze Selassie is almost 100 percent certain to have fathered dead teenager Rhiana Moore's unborn baby, Supreme Court heard yesterday.

Selassie is alleged by prosecutors to have been involved in a secret relationship with the 14-year-old before stabbing her to death last May. He denies premeditated murder.

DNA was taken from both Rhiana and the female foetus dubbed "Baby Moore" by investigators, and Selassie, 33, agreed to give his DNA to detectives.

Listing the results yesterday, Florida-based forensics expert Candy Zuleger said the probability of Selassie being the father is 99.9 percent based on statistics from the US African-American population. The odds of someone other than Selassie being the father are 26 billion to one.

Ms Zuleger is currently working on creating a DNA database and statistics for Bermuda, but has to rely on US statistics at present.

She also analysed samples of blood found in Selassie's car by Florida-based bloodstain pattern analysis expert Jan Johnson, who also gave evidence yesterday.

The first was what Ms Johnson described as bloody fingerprints or handprints on the interior side of the driver's seat. Ms Zuleger said there was a mixture of DNA found when she analysed a cutting from the seat, and Rhiana and Selassie's were both in the mixture.

A sample from the front passenger seat showed DNA from three or more individuals. Rhiana and Selassie were possible contributors to the mixture. A sample from a different area of the same bloodstain showed a full DNA profile matching Rhiana.

Blood from the passenger floor in the car matched Rhiana as a major contributor. A minor contributor was also shown, but did not match anyone that Ms Zuleger tested for.

Rhiana's DNA was found in blood on the passenger front door and footwell.

Her DNA was a major contributor to blood found beside the handbrake with Selassie a possible minor contributor to the DNA mix.

Ms Zuleger agreed with defence lawyer John Perry QC that she could not say when the blood got into the car. However, she explained that DNA gets degraded by heat, so if the blood was in the car in hot weather, she might not be able to detect it within a few days due to degradation.

Rhiana, a CedarBridge Academy student from Devonshire, went missing after attending a church youth group on the evening of May 30, 2008. Her body was found at the water at Blue Hole Hill Park in Hamilton Parish the following morning.

According to prosecutors, Selassie was seen having an argument with an individual in his car in St. David's on the night in question, and also driving at speed away from Ferry Reach in St. George's. Forensic pathologist Chitra Rao told the trial earlier this week that she believes Rhiana was stabbed when she was seated or standing, with her body dumped in the water after the killing.

The case continues.
