Jail records indicate a federal charge against Boelter, which could keep him in custody, even if he could post bail.

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

Vance Luther Boelter, 57, was arrested on Sunday for allegedly killing a Minnesota Democratic state lawmaker and her husband while posing as a police officer, Governor Tim Walz said.

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.

First-degree murder charges could still come against the man charged in what officials say were politically motivated shootings in Minnesota.
