A jury has heard the man accused of murdering Gatton schoolgirl Jayde Kendall searched for "best way to dispose of a body" on YouTube the day before he killed her.
Brenden Bennetts has pleaded guilty to manslaughter but is on trial in the Brisbane Supreme Court for murder after denying he intended to cause Jayde's death.
The 16-year-old is believed to have been killed shortly after Bennetts picked her up from school on Friday, August 14, 2015.
The court has heard Jayde's body was too decomposed to determine a cause of death when it was discovered in a field on the outskirts of town 13 days later.
Police computer analyst Neil Robertson testified on Monday Bennetts had used his phone on August 13 to search on YouTube for "best way to dispose of a body".
However, it is not possible to tell what videos, if any, the then-18-year-old actually looked at after he made the search.
Bennetts' trial is due to continue on Tuesday.
