A new boyfriend, who had been caring for the suspect’s cat while she was holidaying, then came across the victim.
The couple then buried the body in the garden with the help of an accomplice.
Prosecutors suspected that the murder may have been motivated by an unhappy relationship.
The woman was known to have often argued with her partner and he was allegedly psychologically abusive towards her.
Birgit Schwerdt, the woman’s lawyer said that she admitted to the killing.
“The particular issue is in working out the background and establishing a motive,’’ Schwerdt said.
Her client is set to give testimony in the trial, although Schwerdt has said that she would ask for this to be done in a private hearing, citing the intimate nature of the case.
