54-year-old Bo Krister Olsson has reappeared in Adelaide Supreme Court this week, with further details regarding the murder of two Millicent women revealed.
The Advertiser reports - defence barrister Bill Boucaut SC say the alleged crime was reportedly linked to the drug ice, with Mr Olsson's use reported "escalated" at the time of the incident.
63-year-old Sherril Pountney was reportedly bashed to death, with 84-year-old Patricia Phillips believed to be strangled.
Olsson then turned up days later at Berri, confessing to Berri Police officers.
The bodies of the two victims were then discovered in the Plunkett Terrace home.
According to the Advertiser Defence Barrister Bill Boucaut SC has asked the court to consider a discounted sentence, taking into account Olsson's confessions and guilty plea.
Olsson confessions were entered well before prosecutors were scheduled to file evidence against him.
He has been remanded into custody, and is scheduled to be sentenced on April 5th.
