Residents of Brisbane s bayside are being asked to help find a missing dog, who ran off after her owners were killed by an allegedly stolen car on Tuesday afternoon. A 31-year-old woman, who was reportedly six months pregnant, and 37-year-old man were walking their dogs in Alexandra Hills when a LandCruiser, driven by a 17-year-old, allegedly hit a truck and rolled, hitting the two pedestrians. Police allege the teen ran from the intersection of Vienna and Finucane roads before he was arrested by police and charged with a string of offences, including two counts of murder. One of the couple s dogs, Frankie, was still missing on Wednesday morning, prompting a local councillor to ask her constituents to keep an eye out for the animal, who she said requires medication and could be injured.
