Court hears how accused murderer Brenden Bennetts searched 'best way to dispose of a body'

Brenden Bennetts has admitted the schoolgirl's manslaughter but the prosecution insisted he stand trial for murder.

Brenden Bennetts searched for "best way to dispose of a body" on YouTube the day before he killed Australian schoolgirl Jayde Kendall, a murder trial has heard.

However, it is not possible to tell what videos, if any, the 18-year-old actually looked at after he made the search.

Bennetts, now aged 21, has pleaded guilty to manslaughter but is on trial in the Brisbane Supreme Court for murder as he denies he intended to cause Jayde's death.

The jury has heard Jayde and Bennetts started texting each other on Thursday, August 13 after the pair crossed paths at the McDonald's where the 16-year-old worked.

Jayde previously went out with Bennetts' friend Matthew Ross but the two had allegedly not moved in the same social circles for some time.

The court heard on Monday Bennetts used his phone to search for "best way to dispose of a body" at 12.19pm on the Thursday but police could not determine if he looked at any of the search results.

Bennetts picked Jayde up after school about 3.25pm the next day in his distinctive red Toyota Corolla and was captured on CCTV driving out of town.

He then allegedly texted Jayde's bank account PIN to himself at 3.58pm.

The court heard Bennetts' phone allegedly communicated with two cell towers north of the isolated field where Jayde's body was found between 4.24pm and 5.01pm.

Telecommunications specialist Detective Sergeant Adam Riley testified Jayde's phone did not communicate with a cell tower outside the Gatton township during those times, possibly because it was out of battery, turned off or on aeroplane mode.

The court heard Bennetts used Google Maps to find his way back to town, where he was captured on CCTV withdrawing $70 from Jayde's account at a Commonwealth Bank ATM.

Bennetts allegedly deleted Jayde as a contact from his phone as well as any text messages they had sent to each other.

The court heard Jayde and Bennetts sent 48 messages to each other on the mobile app Snapchat but those images could not be recovered by police.

Jayde's body was found in long grass on August 27 by retiree Tom Tate, who was investigating a strange smell on his property.

Bennetts has pleaded not guilty to murder.
