VANCOUVER -- A row of bright flowers lined the entrance of Usha Singh’s Vancouver home Thursday, as neighbours brought tributes and shared memories of the 78-year-old. Singh died in hospital after being attacked in her home on Sunday, by two men police said were posing as police officers. Neighbour Caroline Loughran says the retired caregiver used to visit her mother-in-law and other seniors at a local long term care home. “She was very kind and caring towards them,” she said. “She was a lovely gentle person, and she certainly didn’t deserve to die in this way. Nobody does.”
