MURDER TRIAL: Blood stains found in Edwards' home
BLOOD stains were found at Sharon Edwards' Grafton home that matched DNA found on her clothing, a court has heard.
Senior Sergeant Scott Gane of the Lismore Crime Scene Investigation branch gave evidence in the Coffs Harbour Supreme Court on Tuesday as the trial against John Wallace Edwards, 62, who has pleaded not guilty to the murder of his estranged wife Mrs Edwards, continued.
Mrs Edwards was last seen four years ago after spending a night out at a South Grafton pub.
The court heard forensic investigations of the Edwards' Riverdale Court, Grafton home found two blood stains on a couch in the upstairs family room - one on the headrest and one on the armrest.
Snr Sgt Gane confirmed DNA samples of the blood identified on the headrest belonged to a woman and that on the armrest was a mixture that included the same blood as on the headrest.
The court heard no other areas tested positive for detectable levels of blood.
Snr Sgt Gane told the court a white blouse and pair of pink jeans were seized as evidence from the Grafton address and identified using CCTV footage as the clothing Mrs Edwards' was wearing at the Good Intent Hotel the night she disappeared. Several other clothing items including a nighty were also seized.
The court heard DNA matching that in the blood stains was identified on the pants and nighty.
Snr Sgt Gane said investigators also attended the Edwards' Lawrence home where Mr Edwards' white Toyota Hilux ute was examined and a woman's nighty found in the passenger footwell was taken as evidence.
DNA results included a match to Mrs Edwards' clothing.
Snr Sgt Gane said the accused's ute returned no traces of detectable blood.
The court heard if the ute had been used to transport a body there would "not necessarily" be detectable substances left behind.
"It would depend on whether there were injuries that produced blood staining," Snr Sgt Gane said.
He said a body could have been placed on top of other items that were later removed or the car could have been thoroughly cleaned to remove all traces.
The court heard the DNA found on the blood-stained couch, Mrs Edwards' clothing and the nighty in Mr Edwards' car could belong to the biological mother of Joshua Edwards - Mrs Edwards' eldest son.
Snr Sgt Gane confirmed there was no way of obtaining a DNA sample from Mrs Edwards.
Defence barrister Peter O'Connor asked Snr Sgt Gane about the blood stains on the couch.
In reading from the statement of the investigator who took the blood samples, Mr O'Connor said the officer couldn't comment on the age or cause.
Snr Sgt Gane said investigators cannot comment on the age of blood.
The trial continues before Justice Robert Hulme.
