A NSW couple, Daniel Hasapis and Bonnie Cullen are facing court today after a woman they allegedly kept captive for three days in a Wyong unit on the NSW Central Coast escaped and led police to find the body of an allegedly murdered man inside.

According to local authorities the body belongs to 52-year-old Sean Froggatt, a neighbour of the couple. The victims and the two accused were known to each other, SMH reported.

Speaking to media on Sunday, Detective Superintendent Chad Gillies said that the woman who escaped had sustained “very serious physical injuries including burn marks while detained against her will since Australia Day”.

The detective revealed the woman who informed police was there at first of her own free will, however, according to her statement she did not expect that turn of events.

Hasapis, 30, was arrested and charged with murder and kidnapping in company with intent to commit a serious indictable offence occasioning actual bodily harm. His alleged accomplish, Ms Cullen, 33, was charged with concealing a serious indictable offence.

Police are now investigating all potential alleged motives or reasons, canvassing witnesses and potential CCTV while forensics have been collecting evidence.

Anyone who may have information relevant to investigators is urged to contact the station or Crime Stoppers on 1800 333 000.
