A neighbour discovered Ms Moss' body at about 10.45am last Wednesday in her apartment on Beaconsfield Parade, Middle Park Police believe the widower was killed sometime between noon on Tuesday and the time she was found. Detectives are pleading for any information from anyone who had seen Ms Moss in the 24 hours before her body was discovered, or who may have been aware of her appointments. Detective-Inspector John Potter said it was a "possibility" Ms Moss may have let in her attacker. He said there was no sign someone had forced entry into the two-bedroom apartment and all visitors needed to be buzzed through a secured front door to gain access. Police have set up an information caravan at the bottom of Ms Moss' building. Officers are delving into Ms Moss' business associations and interests. Insp Potter said police had spoken to many in Ms Moss' large circle of friends and had also canvassed the neighbours about any suspicious activity in the hours leading up to her death. But so far police have been unable to find a reason anyone would want to harm the popular grandmother of four. "We are looking at everything in regards to her activities and any associations she had," Insp Potter said. We are looking for any potential clue or conflict. Friends at the Albert Park Yachting and Angling Club, were Ms Moss was a member for more than 15 years, said she had no enemies. Jenny was popular, well-liked. She always had a smile on her face and was down to earth. "She never had a bad word to say about anyone, I don't think it was in her nature," said club president Phil Langdon. Ms Moss' late husband Hal ran a successful lingerie business which he sold before dying. Their two adult children, Tara and Derham, also ventured into the clothing business. Ms Moss had lived alone in the apartment since 1999 and could often be seen at the nearby shops in her green BMW.
