HASTINGS, Minn.— A Minnesota man told investigators a married couple “freaked him out” before he ran them over in his minivan, according to a criminal complaint Monday charging him with second-degree murder.

Prosecutors in Dakota County say 36-year-old Jonna Kojo Armartey hit and killed 58-year-old Diane Peterson and 74-year-old Roger Peterson of Eagan on Thursday near a strip mall. The couple died after being taken to a hospital.

County Attorney James Backstrom says the couple appear to have been targeted by Armartey for unknown reasons.

The criminal complaint says Armartey told investigators the couple “freaked him out” so he ran them over them “going fast and hit them hard.”

He remains in county jail on bail set at $1.5 million.
