The jury was deadlocked at Spector's first trial in 2007
Phil Spector's defence lawyer has rested his case at the producer's re-trial in Los Angeles for the murder of film actress Lana Clarkson.
Doron Weinberg ended on evidence from a memory expert, there to cast doubt on a prosecution witness who said he heard the producer admit to killing someone.
Mr Spector, 68, was told of his right to testify but he chose not to take the stand in his own defence.
He is accused of shooting dead Ms Clarkson at his home in 2003.
Spector's defence has argued Ms Clarkson was suicidal and killed herself.
Forensic psychologist Elizabeth Loftus, a professor at the University of California and author of 22 books on human memory and witness testimony, told jurors that witness observations could be influenced by stress, lighting and time.
But prosecutor Alan Jackson suggested she was "to a certain degree, a professional defence witness".
Ms Loftus acknowledged she has rarely been asked to testify by prosecutors.
The judge told jurors that testimony in the trial would conclude next week.
