Police called paramedics to a red-brick unit block on McLeod Street in the Sydney suburb at 1.48pm on Monday. It is understood police were initially called to the unit because of a "concern for welfare" when the woman didn't show up for work. Officers who arrived at the unit block are believed to have seen the woman's body through a window or door. When ambulance officers arrived, they found the body of the 32-year-old woman. On Tuesday morning, police were still guarding the unit block as well as three wheelie bins inside the unit's garage, which were cordoned off by police tape. Five forensic officers came out of the building about 10am holding yellow bags, black boxes and a blue esky. Residents told Fairfax Media that detectives spent most of Monday knocking on doors and interviewing people who live in the street. One resident, who lives next door to the unit block, said there were at least five police cars and two forensics vans in the usually quiet, tree-lined street until late on Monday night. Inspector Elise Teeling, of Harbourside Police, said: "It is an ongoing investigation right now and it's pretty new." A post-mortem examination would be carried out to determine the cause of death, police said.
