Vance Boelter has been charged in the shootings of two Minnesota lawmakers and their spouses, and the FBI says that he visited the homes of multiple other elected officials the night he killed Minnesota Rep.

New details about Vance Boelter, accused of fatally shooting a state lawmaker and her husband, were revealed in court documents.

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.

She remembers friendlier encounters with Boelter and his wife before Sunday night arrest for killing of former House Speaker Melissa Hortman.

A spokesperson for Sen. Tammy Baldwin confirmed that the senator was included on the "list of names" authorities say belonged to the man accused of fatally shooting a Minnesota state representative and her husband and wounding a state senator and his wife.

These are the items investigators say were found inside Vance Boelter's vehicle, suggesting the carnage could have been even worse.

The judge presiding over the upcoming burglary trial of state Sen. Nicole Mitchell is postponing the trial given the slaying of Rep. Melissa Hortman, who was fatally shot along with her husband in their home Saturday morning.

The manhunt for the man suspected of shooting two Minnesota lawmakers and their spouses continues into Sunday, with sources telling ABC affiliate KSTP that his wife has been detained for questioning.
