Gill disappeared on February 22 last year. Her body was discovered that same night in the boot of her burnt BMW at the Diep River train station.
On Monday, police cellphone analyst Reese Harvey said that Rob’s phone had been placed in the Diep River vicinity at 2.37pm. He said that based on evidence already before the court from a licence plate recognition expert, Rob’s car was parked at Diep River train station at the time.
Harvey said he had analysed data from both Rob’s phones as well as Gill’s phone.
On the eve of Gill’s disappearance, her phone was switched off from 9.04pm and was only activated again on the morning of her disappearance at 7.09am when she received a 28-second call. It was not activated again thereafter.
