Packham is on trial for murder and obstructing the ends of justice. He is accused of killing his wife, Gill Packham.
Gill went missing on February 22 last year. Her body was discovered hours later in boot of her burnt BMW at the Diep River railway station.
On Monday, defence advocate Craig Webster called Diep River Police Station officer Steven Jan, who commissioned the statement of witness Keenan Thomas.
Thomas testified that he saw Packham at the scene of the burning car in Diep River on the night in question.
