Police in Calgary say they're treating the disappearance last week of a woman and toddler as potential homicides. They say they have found no evidence that 25-year-old Jasmine Lovett or her 22-month-old daughter Aliyah Sanderson are alive. Police say the last time they were seen was in the suburban community of Cranston on the evening of April 16. Police say they have a suspect in custody. They say they don't believe it's random because the suspect and the missing females knew each other. Investigators are searching Cranston and the area surrounding the hamlet of Bragg Creek west of Calgary for evidence.
