A man impersonating a police officer shot the couple to death at their home in what authorities are treating as a politically motivated murder.

Former Minnesota House Speaker Melissa Hortman and her husband Mark Hortman were laid to rest at a private funeral on Saturday, weeks after the two were killed in what authorities have called a "politically motivated assassination.

On a warm, humid Saturday morning, grieving loved ones gathered at The Basilica of Saint Mary in Minneapolis to honor Minnesota’s former House Speaker and her husband, whose shocking killings in an attack earlier this month stunned the nation.
