BLOOD splatter on walls and tiled floors have shown a jury just what happens when someone is shot in the head with a shotgun at close range.
In the third day of the trial of Jamie Rex Teichmann for murder, the jury heard from expert witnesses who examined the crime scene.
In December 2010, Carl Upson's body was found sprawled on his back on the tiled floor of a train carriage that had been converted into a home at a property near Esk.
The jury has seen gruesome photographs throughout the trial and yesterday heard an analysis of what could have occurred during the shooting, based on blood splatters, pools and droplets on the walls and floor.
Mr Upson's body was found in the kitchen area, with his arm partially hanging out the carriage's door, Brisbane Supreme Court heard.
It is believed he was shot from about 50cm to a metre away.
An expert described how droplets of blood found on the other side of the room, including in the lounge room metres from the kitchen, showed how the force of a heavy-impact weapon, such as a shotgun, could have caused a mist of blood particles in a room.
Similar to what would occur if an aerosol can was sprayed, this would allow blood droplets to be dispersed and fall onto the floor well away from the body, the jury heard.
Earlier in the trial, crown prosecutor David Meredith said Mr Teichmann's story was that Mr Upson was shot while the two men were wrestling.
But Mr Meredith said this version would have been impossible, based on the gun's length and Mr Upson's injuries.
He also said it appeared the gun had been placed next to Mr Upson's body and was not dropped.
The trial continues.
