The service at the NSW Police wall of remembrance honoured Constable Lay, who died when the marked patrol car she was travelling in collided with a tree in Redfern, in the city's inner-south, during an urgent response to a reported vehicle theft.
Her mother, Tamara, and her partner, Daniel Vasquez, attended Tuesday's service, pictured amid a sea of blue as the force paid tribute. The tragedy has been described as a rare loss carrying intensified grief that has reverberated throughout the entire force, with the state's most senior officers and politicians pausing alongside officers to remember those who died in service.
National Police Remembrance Day is marked each September 29, with police across the country gathering at memorials to remember their fallen comrades.
