"Our beautiful girl has been reunited with our beloved wife and mother. Fly high our darling angel, until we see you again Rissy."

The spokesman said the Coast woman was remanded and will face court again on Monday.

Police will also allege an Alexandra Headland man, 28, also helped and have been charged with one count of accessory to murder after the fact.

The resident of the unit where Sikorsky remained for more than a day revealed he unknowingly let the suspect into his home.

The man, who wanted to be known only as Joe, said a long-time friend called him on Friday afternoon and asked if he and Sikorsky could come over.

Police were alerted when a property manager recognised Sikorsky from the news.

"I was completely in shock, I had no idea," Joe said.
