The trial of Pawel Relowicz, who is accused of raping and murdering Hull student Libby Squire, enters its second week today.
Despite issues last week with the weather meaning jurors struggled to make it to court, the trial is expected to get under way again today from Sheffield Crown Court.
Relowicz, 26, of Raglan Street in Hull, denies the charges against him.
Jurors heard from the prosecution last week about how Relowicz "stalked" the 21-year-old student on February 1, 2019 as she walked down Beverley Road.

The jury were shown CCTV footage and interactive maps of Relowicz "prowling" the area looking for a target. The prosecution say he "intercepted" her before driving her to Oak Road Playing Fields where he raped and killed her.
The prosecution told how Relowicz has previously admitted crimes including voyeurism and burglary and, when his car was searched on February 6, a pink holdall containing sex toys and two masks was found.
Richard Wright QC told the jury that just hours after killing Libby, Relowicz masturbated in Newland Avenue and a condom containing semen matching his DNA profile was found days later.
Libby's body was found in the Humber Estuary close to Spurn Point on March 20.
The court heard how a post-mortem examination could not conclude how Libby had died but an internal swab was taken from Libby which detected sperm cells and the majority yielded a DNA profile that matched Relowicz.
The jury was told that it is one billion times more likely that the DNA detected in the sperm is Relowicz’s than it is DNA from another person unrelated to him.
Libby's mum, Lisa, paid tribute to her daughter in a statement read out to the court. She said Libby "loved life", "worked really hard" and thrived during her time at university in Hull.
