The trial of Brenden Bennetts for the 2015 murder of Gatton schoolgirl Jayde Kendall is close to ending with final submissions set to be delivered.
Bennetts, now aged 21, has spent six on days on trial in the Brisbane Supreme Court after pleading guilty to manslaughter but not guilty to murder.
The jury has heard Bennetts is believed to have killed Jayde less than two hours after he picked the 16-year-old up from school on Friday, August 14.
He then dumped her body in an isolated field on the outskirts of town and withdrew $70 from her bank account at an ATM.
Jayde's body was too decomposed to determine a cause of death when it was discovered 13 days later by retiree Don Tate, who was investigating a strange smell on his Upper Tenthill property.
Forensic pathologist Ben Ong testified the hyoid bone in Jayde's neck may have been fractured, an injury consistent with manual strangulation.
However the teenager did have a defect that may have caused the possible break.
Three former girlfriends of Bennetts have testified they engaged in consensual choking while having sex or making out with him.
The court has heard Jayde and Bennetts sent each other sexually suggestive text messages before they met, but Bennetts told police she asked him for a lift out of town because she was upset about school.
Police computer analyst Neil Robertson testified on Monday Bennetts used his phone on August 13 to search on YouTube for "best way to dispose of a body".
However, it was not possible to tell what videos, if any, the then-18-year-old actually looked at after he made the search.
Prosecutor Vicki Loury QC and defence barrister Michael Copley QC are scheduled to give their closing submissions on Wednesday.
