The Ammanford teenager accused of murdering Kelly Hyde told police that he did not like walking along the bridlepath where the 24-year-old hairdresser was brutally attacked because it is "weird".
Swansea Crown Court spent much of today listening to transcripts of the initial interviews between the 17-year-old, who cannot be named for legal reasons, and police.
During his first meeting with Detective Constables Andrew Cousins and Jamie Thacker, the boy said: "I do not like that path, I never have.
"I don't hang about there, I don't like it. It's weird."
Throughout today's hearing, prosecutor John Hipkin questioned DC Cousins regarding the teen's explanation of his whereabouts on the morning that Kelly was killed.
The boy told officers that he had got out of bed at around 10.30am, ate breakfast and watched part of the police comedy movie Hot Fuzz.
He said that although he was feeling a little under the weather he was delighted when his step-father received a phone call offering the teen work the following day.
"I was feeling good," the teen told officers.
"I had a job in the morning. I was happy."
Earlier on, the forensic scientist who examined shoe prints found at the scene told the jury that his findings offered only limited support to claims that they matched those made by footwear belonging to the teenager.
Robert Farmer said that: "The impressions made at the scene have been matched footwear with the same under-sole pattern as Lonsdale trainers.
However, under cross-examination from Huw Davies QC, Mr Farmer confirmed that he was only able to offer 'limited support' that the accused's shoes had made the marks.
Mr Farmer explained that forensic scientists findings ranged in certainty through eight grades, from no support to conclusive proof.
Limited support, he told the court, was the second weakest of all findings.
He said that he left the house at around 11.40am to take his dog for a walk and to secretly smoke a cannabis joint away from his home.
He claimed that he walked along the bridleway just metres from where Kelly's battered body would eventually be discovered.
The teen said that he reached a concrete bridge some distance beyond the bridlepath where he smoked the joint and then returned home the same way.
As he made his way along the bridlepath for the second time he met Mrs Sara Williams, a riding instructor taking her horse out for its morning exercise.
He told officers that he spoke briefly to Mrs Williams, although was himself unaware of her name.
He said that while he was speaking to Mr Williams he spotted a stray dog further along the path.
The stray is believed to have been Kelly's pet whippet Scrappy.
He told officers that after speaking to Mrs Williams he returned home and spent the rest of the day indoors.
The teen denies murder.
The case continues.
