Jury deliberating in teen murder trial

A jury has begun deliberating in the trial of a Queensland man accused of killing pregnant teenager Tiffany Taylor seven years ago.

Rodney Wayne Williams, 68, has pleaded not guilty to murder in Brisbane Supreme Court.

Tiffany, 16, was last seen leaving a motel south of Brisbane in July 2015.

The Crown alleges Williams and Tiffany arranged to meet after connecting on a dating website.

Williams picked up Tiffany outside the Waterford West motel after telling her he had money for sex before driving to a remote industrial area where he likely killed her, crown prosecutor Caroline Marco said.

He then drove to his "old stomping ground" at Fernvale, 100km northwest of Logan, to dispose of the body, the Crown alleges.

Footage on motorway cameras and phone tracking details on cell towers indicate that Tiffany was in the car with Williams, the court heard.

Tiffany's blood and DNA were also found in Williams' vehicle.

Williams is accused of creating a false trail of communication with Tiffany on the dating website afterwards, with his last message reading: "Sorry I didn't turn up, decided I wasn't going to pay for it".

He was intercepted by officers at a Brisbane train station with a bag of clothes and sentimental items in August 2015, a day before he was supposed to be interviewed by police, the court heard.

Williams then told police a "litany of lies", Ms Marco said.

Defence barrister Kim Bryson told the jury that Williams had lied to police but had not killed the pregnant teen.

Ms Bryson earlier told the court that Tiffany had an "abusive and dysfunctional relationship" with a violent and controlling boyfriend that started when the girl was 12.

The jury began deliberations in the three-week trial before Justice Peter Applegarth on Friday afternoon but was sent home to resume on Monday.
