A POLICE scientific officer has described two blood stains, depicted in a photo shown to the jury, found in Allison Baden-Clay's silver Holden Captiva.
Senior Constable Carl Streeting told Brisbane Supreme Court that there was a transfer stain and a drop.
"A transfer blood stain is simply when an object, which could be a person or any object with the source of blood, comes in contact with the surface and transfers the blood onto that surface," he said.
"(The drip) is a flow rivulet of blood.
"The only force acting on this blood is gravity.
"Some force would have had to have been applied for the mere fact that it transferred.
"There's no current way to have a look at a blood stain and say it's been there for x amount of time."
Crown prosecutor Todd Fuller told the jury during his opening address that the blood stain had tested positive for Allison's DNA.
Sen Const Streeting said he also examined Gerard Baden-Clay's razor blade and did not find any presence of blood.
He said water could dilute the blood and water could have washed away any blood if Mr Baden-Clay had cut his face shaving that night.
The court saw a photo of Mr Baden-Clay's chest which showed red abrasions.
Sergeant Anthony Vernados, who took the photo, said Mr Baden-Clay consented to police taking photos of his chest and face injuries and scraping his fingernails.
Gerard Baden-Clay gave doctor inspecting scratches a business card
WHILE Gerard Baden-Clay was having injuries to his face documented, he gave the doctor a business card to help her move closer to the clinic.
GP Candice Beaven said she learned his wife Allison was missing about five minutes before the consultation and then recalled seeing something on the news.
She said Mr Baden-Clay, towards the end of the consultation, asked her how long she had been at the Kenmore practice and whether she lived locally.
"I said I'd been at the practice for about a year and a half at that stage and that I lived out past Springfield Lakes but that I was looking to live closer to the area," she said.
"He handed me his business card and said that he might be able to help me with that."
Dr Beaven said she saw Mr Baden-Clay about 8.30am on April 21, 2012.
"From what I could see there were three superficial vertical abrasions to his right cheek," she said.
"They looked like they were fairly recent.
"He said they were from the morning before he consulted me.
"He seemed reasonably composed … but I could tell he was anxious and a little bit on edge.
"I could tell he was in a rush to get through the consultation and get on with things.
"He remained anxious throughout the consultation and I got the impression he was in a rush.
"But towards the end he seemed quite friendly."
Dr Beaven told the court she believed police had told Mr Baden-Clay to document his injuries.
Defence barrister Michael Byrne suggested his client had seen the doctor after consulting his lawyers, not police.
Dr Beaven said that was not her recollection from the day but accepted she could be wrong.
Forensic expert says scratches more likely from fingernails, not razor
THE scratches on Gerard Baden-Clay's face most likely came from fingernails rather than a razor blade, a forensic expert has told a court.
Dr Margaret Stark, who is the director of the clinical forensic medical unit within NSW police force, said she had looked at photographs of Mr Baden-Clay to make her assessment.
"From the photographs they look like abrasion injuries," she said.
"An abrasion is damage to the superficial part of the skin which is the result of contact with a rough surface.
"You've got three abrasion injuries running vertically down the cheek and one running in an elliptical way."
When questioned, Dr Stark said the aging of injuries was imprecise but the yellow on the photograph suggests some evidence of healing while the reddening suggested something slightly more recent.
"This is interpretation from a photograph and it's must better to see the injury in the flesh," she said.
"When they occurred is very difficult to say.
"It depends on the individual patient, the individual person, their individual health and how they're healing.
"It's very imprecise.
"They're not fresh, as in caused in the last couple of hours.
"They're hours or days old but you couldn't be more definite than that really."
Dr Stark said such abrasion injuries result from damage to the superficial part of the skin.
"These particular injuries are typical of fingernail scratches," she said.
"It's not diagnostic, it's not 100%, but in my experience they are commonly seen.
"This is a common presentation of being scratched with fingernails."
Dr Stark, commenting on the shape and direction of the scratches, said fingernail scratched happened in a dynamic situation which could explain their differences.
She said the scratches would hurt so the person threatened by another person clawing at them would be pulling away.
"You won't necessarily get three lines, four lines or five lines, people will pull away," she said.
Dr Stark said the person scratching would have to have nails to make a mark.
"If somebody has nails bitten down to the quick then they're not going to have the nail to cause scratches," she said.
"If a longer nail, it might be earlier to scratch them.
"I don't think you can say anything about the length of the nail.
"It's possible they could have been caused by those nails."
Dr Stark said, having assessed thousands of injured victims, a razor was unlikely to have a wound of that width.
"In my experience, the injuries to the face are typical of a fingernail injury," she said.
"I've seen injuries sustained from razors and razor blades and they're not typical of a razor injury but you can't exclude it.
"You've usually got a finer injury because the blade is sharper than nails.
"They just seem to me to be more typical of fingernails rather than the finer abrasion you get from a razor, even if it is blunt."
Defence barrister Michael Byrne suggested the "gold standard" for such an analysis was for an expert to examine the injured person in the flesh.
Dr Stark agreed and confirmed she had not examined Mr Baden-Clay in person.
"You cannot say and do not say that those marks on the face … were caused by fingernails?" Mr Byrne asked.
"Not 100% that's absolutely correct," Dr Stark said.
"There are serious limitations in interpretation without that forensic medical examination?" Mr Byrne asked.
"There are also serious limitations in interpretations of photographs for forensic purposes?"
Dr Stark agreed.
She also agreed she could not speak to the skill of the photographer, photograph exposure, colours or the printing process.
Police think Gerard Baden-Clay's face cuts were suspicious
GERARD Baden-Clay told police he understood the cuts on his face the morning he reported his wife Allison missing were "suspicious" to others.
"I cut myself shaving this morning and everybody thinks that's suspicious," he said.
Senior Constable Cameron Simmons, during a recording conversation sitting at the Baden-Clays' table in their Brookfield home, told Mr Baden-Clay "it doesn't look like a shaving cut to me".
"I haven't brought new razor blades for six months," Mr Baden-Clay said.
"I have to be as careful as I possibly can.
"This morning I was rushing.
"I shaved down and then back and sideways to try and make it as smooth as possible.
"I was rushing. (My daughter) had just come in."
Mr Baden-Clay said he cut his hand while at a house linked to his real estate business the day before.
"I was using a ratchet ... replacing a light fitting," he said.
Mr Baden-Clay was running over the past 12 hours with Sen Const Simmons after already talking to other police.
"She was still up watching the footy show," he said.
"I wasn't feeling great so I just went to bed.
"Sorry I feel like I'm repeating everything a third time
"My brain is just … Maybe you just ask me questions and I'll tell you what you want to know.
"I got up just after 6pm and she wasn't here
"That's not unusual. She goes for a walk in the morning often.
"I'm a very heavy sleeper."
Mr Baden-Clay said sometimes he or Allison might sleep on the couch but "not necessarily because of some kind of disagreement".
He said he set Allison's hot rollers going because "I do that sometimes".
Mr Baden-Clay said Allison had talked about two walking routes with him.
"One is along Gold Creek Road about as far as the old people's home. There's a bus stop and bench there; sometimes she just sits on the bench," he said.
"The other is around the school.
"Some mornings she just likes to go and clear her head."
Mr Baden-Clay said the counselling session he had with his wife gave them a number of positive strategies to move forward following his affair with Toni McHugh.
"I've got to rebuild the trust with her and that's what I'm working on," he said.
"We were feeling pretty positive about it actually.
"She spent an hour with me on my own."
Mr Baden-Clay said they also had difficulties because of Allison's depression.
He said there were periods when she could not drive and "it was pretty bad".
But he said she had worked through it all with a psychiatrist and medication.
"We had a basket full of medication above the oven," he said.
"She had reduced the dose. She had been off it and then back on again.
"It's been an ongoing issue for the best part of 10 years.
"She suffers from panic attacks and she would pass out sometimes.
"It was a very, very dark period.
"Once we were able to get it all under control … we just dealt with it."
Updated 11.06am MURDER accused Gerard Baden-Clay told police he wanted them to ramp up their search for his wife Allison the morning he reported her missing.
He said he was happy to answer any questions but he would prefer to be driving around searching for her.
Police officers told Mr Baden-Clay they did not want to alarm him but because her absence was unusual they wanted to ramp up the police investigation "to find your wife as quickly as possible".
"I want it ramped up," Mr Baden-Clay said.
Sergeant Andrew Jackson said Allison might walk in to the home in five minutes but it was better to dot the Is and cross the Ts.
In a recording played while Sgt Jackson was in the witness box in the Brisbane Supreme Court, Mr Baden-Clay said he got up just after 6am on April 20, 2012.
"Kate and Allison are going to a seminar today. It starts at 8.30am so I needed to be available to do the school run for the kids," he said.
"I do my usual sh** shower and shave. Checked my emails while sitting in the toilet.
"I was rushing because I needed to get the girls up.
"They were tired all had cross country the day before."
Mr Baden-Clay told police his wife was born on July 1, 1968 and that they were married on August 23, 1997, - making it their 15th wedding anniversary that year.
He said his wife usually went out for 20 to 40 minutes for her walk - that the longer walks were when she sat down on a bench for a period rather than walking longer.
Mr Baden-Clay said he could not think of anything that would have set her off and she had never disappeared like this before.
He said she would sometimes not reply to his text messages when she was p***ed off with him.
Mr Baden-Clay said a counsellor on Monday, four days prior, suggested they set aside 15 minutes a night for "Allison to be able to vent and grill me".
He said they did that but nothing unusual came of it.
When asked whether she would scream at him, he said:
"No, she's not like that. She would have sworn at me".
"We've had some challenges recently as well," he said.
"The affair I had was with somebody who worked in the business but Allison's quite…"
A female police officer offered a sentence ending, that Allison was "suspicious of the other female workers in the office", and he agreed.
Mr Baden-Clay said he was concerned about Allison not being home because she had a seminar and "she was excited about it".
He said there were also plans for cousins to have a sleepover.
"That's what bothers me and concerns me," he said.
"It's completely out of character."
Mr Baden-Clay has pleaded not guilty to murdering his wife.
EARLIER: THE man accused of murdering his wife told a psychologist that he wanted to build a future with his wife and wipe the slate clean
He also told the same psychologist he blamed his wife's depression for his four-year affair with a co-worker.
Gerard Baden-Clay, 43, is accused of murdering his wife Allison Baden-Clay, 43, in April, 2012.
He reported her missing on the morning of April 20, 2012, telling police she had failed to return from her morning walk.
Her badly decomposed body was located 10 days later underneath Kholo Creek Bridge near Ipswich.
Mr Baden-Clay has pleaded not guilty to her murder.
Relationships Australia counsellor Carmel Ritchie told his Brisbane Supreme Court murder trial on Tuesday she met with the couple in the days before she was reported missing on April 20, 2012.
Ms Ritchie said she had one session with Mrs Baden-Clay on March 27, 2012, at her office in Spring Hill.
She told the court she had asked Mrs Baden-Clay about what she wanted to achieve from the counselling sessions.
"I asked her to define the problems she saw in her life and she said she 'was feeling inadequate, not good enough, I believe I let it happen, Gerard's way is the right way, Gerard has had an affair for the last three years and parenting, Gerard criticises me and I fear one day he will leave," Ms Ritchie said.
"Then when I asked her what she wanted from counselling, in other words what was her goal, she said 'to work on me, to sort lots of issues, especially parenting.'
Ms Ritchie said she met with both Gerard and Allison on April 16, 2012.
She told the court she also asked Mr Baden-Clay what his counselling goals were.
"I also asked Gerard if he would outline for me what he saw as the problems in the relationship," Ms Ritchie said.
"I wrote down his exact words.
"He said, 'Allison does not trust me, she questions me, she says yes when she means no, Allison's disappointment with her life and I used to blame Allison for disappointment in my life.
"Then I asked Gerard what he hoped to gain from counselling.
"He said 'I want to build a future together, no regressing, I want to get on with life and wipe it clean.'
The trial before Justice John Byrne continues.
