It allegedly took months of planning, but the suspect in deadly attacks on Minnesota lawmakers unfolded over a roughly 90-minute time span.

The suspect is accused of fatally shooting Minnesota state Rep. Melissa Hortman and her husband, Mark, at their home. He also shot Minnesota state Sen. John Hoffman and his wife, Yvette, at their home — but they survived the attack.

MINNEAPOLIS (AP) — The man accused of killing a Minnesota lawmaker and wounding another went to the homes of two other legislators on the night of the shootings, intending to inflict more carnage against those on his hitlist, a federal prosecutor said Monday.
