UPDATE: Police have charged a man with a second murder following a 22-month investigation into the shooting death of Carl Upson.
Jamie Rex Teichmann, 37, appeared at Ipswich Magistrates Court yesterday afternoon charged with the murder of the 35-year-old.
Mr Upson died from a shotgun blast in his home at Buaraba, north-west of Ipswich, in December, 2010.
Ipswich detectives were called to his Mount Mulgowie Rd home on December 15 that year, following reports of gunshots in the area earlier in the week.
Teichmann is already in custody awaiting trial for the murder of Michael Desmond Manson, 48, who was found dead in the tray of his own ute on December 10, 2010.
Mr Manson's body was found less than 30km from Upson's and police suspected a possible link between the two killings.
Teichmann, of Kilcoy, was charged with Manson's murder on March 7 last year and has been in custody since.
Teichmann yesterday appeared in the dock wearing a green prison uniform and socks without shoes and did not have legal representation.
The defendant told the magistrate he hadn't hired a lawyer yet because he "didn't know about this until today".
Teichmann asked for the case to be adjourned for "a couple of months", but the magistrate suggested it be brought on earlier to "get things moving".
The case was adjourned until October 24, when the suspect is expected to appear via video link after he requested to "not be brought in" from the prison.
Manson's body was found in a ute parked in bushland near Bolingbroke Rd, Atkinson's Dam.
