Heavily armed and dressed in tactical armor with a silicone mask hiding his face and a police-style badge, Vance Boelter made a convincing police officer – so much so that a real police officer mistook him for a fellow cop.

Ohio Representative Greg Landsman's name was found by the FBI in evidence of Minnesota murder suspect Vance Boelter, leading to increased security for Landsman.

Minnesota Governor Tim Walz said Ms Hortman’s killing was a “politically motivated assassination.” It deepens fears that political polarisation in Donald Trump’s US is leading to increased political violence.

Sorry to Wisconsinites, this is just how the numbers broke down in a recent survey which found Minnesotans are, on the whole, far more generous when it comes to tipping.

Boelter, 57, arrived in federal court in an orange jumpsuit and slippers and was unshackled as he sat next to a defense lawyer, according to a report.
