A man accused of murdering his American girlfriend organised for an trench to be urgently dug a day after she went missing, a court has heard.
Mark Sheridan Waden allegedly killed Priscilla Brooten and disposed of her body before dumping her at a Brisbane rubbish tip nearly a year later.
Waden is also accused of using the US woman's mobile phone after she went missing, posing as her in texts and giving it to a new girlfriend before it was seized by police.
