She was found dead wearing shorts, a long-sleeved top and joggers inside a shower at The Oaks on Market serviced apartments in central Melbourne on Sunday, July 16.

The room was rented by a buck's (bachelor) party, the members of which had travelled from Victoria and the ACT for the festivities.

The group is believed to have met the woman at a nightclub in the city before going back to the apartment about 3 o'clock that morning.

Police are yet to reveal the cause of Rowley's death, but it is not being considered suspicious.

Four men were questioned by police over the death, but were later released without charge.
