Jurors in the attempted murder trial of Abosede Adeyinka have been shown DNA analysis of bloodstains on items belonging to the defendant, accused of attacking an elderly grandmother.
Bloodstains were also found on a wooden-handled knife which prosecutors believe was used to stab 90-year-old Pamela Batten at her home in Lilac Place, Yiewsley on April 27.
The elderly woman had to undergo emergency surgery following the attack and remained in hospital for a month before being discharged.
The jury heard details of DNA taken from the evidence in the trial at Blackfriars Crown Court on Thursday (October 26).
Prosecution lawyer Kevin James Barry detailed to the jury how forensic scientists had proven that the DNA was from blood and had been tested for DNA from both Adeyinka and Ms Batten.
Bloodstains found on the outside of the defendant's jacket, belt and on the knife all tested positive for the victim's DNA.
Jurors were also given the opportunity to examine a handbag which was found to be covered in significant quantities of Ms Batten's blood including a large bloodstain measuring 21cm by 29cm.
The court also heard details of the 8.5cm knife believed to be used in the attack, which was covered in blood in both sides, as well as on the wooden handle.
Bloodstains on the handle and on trainers were not "robust" enough to be tested according to the forensic report.
Mr Barry went on to tell the jury and Judge Peter Clarke QC that the type of staining on the jacket was known as "transfer staining" which involves contact with a bleeding person or with an item wet with their blood.
During testimony given to police, Ms Adeyinka, 52 and from Hayman Crescent in Hayes, said the stains may have come from when she hugged Ms Batten as she left her home.
She went on to say that while she was at the address in Lilac Place on April 27, she had left before the attack and claims Ms Batten was safe and well at the time of her departure.
An alternative explanation given by the carer was that she had helped Ms Batten by bandaging her finger after she cut it.
However the prosecution argued that the large area covered in blood would not support this explanation.
The prosecution rested its case on Thursday morning and the trial was adjourned until 2pm when the defence was due to begin its case.
Defence lawyer Tyrone Silcott told the judge that Adeyinka will be in a position to testify to the court.
The trial continues.
