The double murder, which took place at a farm in the village of Långared outside of Alingsås, was allegedly the result of a carefully planned robbery aimed at accessing the elderly farmers’ safe.

The area where the couple was murdered has been cordoned off since October and on Tuesday, the two suspected murderers were taken to the scene of the crime to see it with their own eyes, wrote the TT news agency.

The two suspects, aged 34 and 40, were arrested in Poland in mid-November. They were taken to the crime scene from prison and were separately shown around the area, each guarded by two members of security.

Journalists, members of the court, defendants and lawyers were also present and a helicopter constantly circled the area.

According to reports, the two men “showed no emotion” during the visit and were “stony-faced” throughout.

The bodies of 69-year-old dairy farmer Torgny Antby, who was killed by a fatal blow to the head with an iron pipe and his 71-year-old wife Inger were found after they failed to turn up for their afternoon performance with the local choir.

At the scene of the murder, there are still blood stains on the walls, along with arrows that police have drawn to show the direction the blood was spilled.

A pile of gravel is also visible in the area where the murderers tried to cover the pool of blood that came from the farmer’s head after the repeated bashings.

The police showed the location of the safe, as well as where the key was hanging.

They then pointed out how the farmer’s wife was most likely asleep in bed upstairs after Antby had been killed in the stable and explained that the thieves strangled her to death with a force so powerful that it broke her hyoid bone at the base of her throat and damaged her windpipe.

She was found with a pillow taped over her face, according to reports.

After prosecutor Daniel Larson decided there was sufficient evidence in May, the two men were formally charged.

“The evidence includes, among other things, the positioning of mobile phones, shoe prints found at the crime scene and that the same unusual cables used to bind the victims were found with one of the men at his arrest in Poland,” Larson said in a statement at the time.

Larson also filed an alternative charge of accessory to murder, theorizing that the men may not have carried out the actual killings, but were instead involved in their preparation and helping the killers make their getaway.

Other evidence tying the men to the crime scene is some toilet paper which contained human excrement from which police were able to take DNA samples, according to the news agency.

The trial of the two men is expected to start on June 4th and last six days.
