Johnathon Dean “JD” Mar

Deadly force

Maple Grove police said they found a man dead of a gunshot wound at a Maple Grove rest stop. An SUV driven by Mar was seen leaving the rest stop. Police said Mar led them on a high-speed chase that ended when Mar crashed into the median of I-694. Mar "emerged from the other with a knife and began repeatedly stabbing himself," according to a statement from the BCA, which added that he "ignored repeated commands from law enforcement to stop and get on the ground." Investigators said that Mar then "charged" officers. Two officers fired.
