The man accused of assassinating a Minnesota Democrat kept an arsenal of weapons in his car, according to police.

Melissa Hortman, the Democratic speaker in Minnesota’s House of Representatives, and her husband Mark were both shot and killed in an attack on Saturday.

Vance Luther Boelter, 47, was arrested on Sunday in connection with the attack after a two day-long manhunt.

On Monday, authorities released images of what they say is Mr Boelter’s SUV, which they claim was abandoned at the Hortman’s home.

Pictures shared by the US Attorney’s Office show at least two AK-47 style rifles and a black gun strewn across the vehicle.

Authorities said that five guns, including semi-automatic assault-style rifles and a large quantity of ammunition were recovered from the vehicle.
