Canberra, Australia ? Australian teenager Natasha Ryan, who disappeared four years ago and was presumed dead, has resurfaced — midway through the serial murder trial of a man charged in her death.

Ryan, now 18, was found Thursday, hiding in a closet at her 26-year-old boyfriend’s home just half a mile from her mother’s home in Rockhampton in Queensland state.

She was questioned Friday by police who earlier interviewed her boyfriend. It was not immediately clear whether charges would be filed.

Ryan’s dramatic reappearance coincided with the trial in a Queensland court of Leonard John Fraser, 51, who was charged with the murder of her and three other women whose bodies have been found.

Prosecutors immediately dropped the charge against Fraser for Ryan’s murder, although the three other murder counts remain.

Natasha Ryan resurfaced this week in Australia, in the midst of the trial of a suspect charged with her murder.

The case has been adjourned until Monday, when Fraser’s lawyers are expected to argue that the other charges also be withdrawn and the entire trial abandoned.

Fraser had pleaded innocent to all four murders.

Ryan disappeared when she was 14. Her family had been so sure she was dead, they had a memorial service for her a year ago.

A police spokesman said officers raided the boyfriend’s house after a tip-off arising from Fraser’s trial.

Ryan’s father, Robert, confirmed his daughter’s identity over the phone by asking her to tell him his pet name for her. She answered correctly.

Detectives questioned the boyfriend, Scott Black, on Thursday night before releasing him and referring the case to the Queensland director of public prosecutions.

Black, a milkman, had been fined $600 in 1998 for obstructing a police investigation in a previous incident in 1995 when Ryan ran away from home for the first time and stayed in a hotel.
