Suspects in the murder of a Birmingham couple were arrested in south Florida, authorities said Friday. Kristin Guillion, 30, was taken into custody Thursday, after parking illegally in the victims' car in Miami Beach, police said. The officer looked up the tag, and discovered it was connected to a homicide, police said. Gullion tried to drive off, and was arrested. Gullion told police the car belonged to her friend, and that "in situations like this her father told her to keep her mouth shut," the arrest report said. Officers Friday arrested Zachary Phillips, 23, after chasing him in a stolen car in Hollywood. The driver, Vivian De La Rosa Toniana, was also arrested. It's unclear if she has any connection to the homicide case. 68-year old Steve Holt and his wife Mary, 67, were found murdered last week at their home on Ninth Court Circle South. Police were called after a neighbor noticed a child with bloodstained clothes came to her home, crying for her grandparents. The child, who was not injured, led police to the crime scene.
