POTSDAM – Five people were injured Friday in what police are calling a “domestic/road rage incident.”

State police said Douglas Matthews, 32, Canton, forced a vehicle driven by Susan Latimer, 65, Madrid, which also held Jenelle Matthews, 32, Canton, and two children ages 5 and 9, off of State Rt. 310 in Potsdam.

Latimer’s vehicle hit an embankment and overturned in a field, and Matthews’ vehicle hit the same embankment and landed on top of Latimer’s vehicle, troopers said.

Latimer, apparently the most seriously injured, was flown to Fletcher-Allen Hospital in Burlington, where she was reported in stable condition.

Jenelle and the two children were taken to Canton-Potsdam Hospital where they were treated for non-life-threatening injuries, according to police.

Douglas Matthews has been charged with felonies, first-degree assault: causing injury through risk of death, and four counts of first-degree reckless endangerment, and a misdemeanor, endangering the welfare of a child, in the road incident.

He was also charged with a felony, third-degree criminal mischief; a misdemeanor, second-degree reckless endangerment; and a violation, second-degree harassment in connection with a domestic incident which occurred earlier in the day.

He refused medical treatment at the scene.

Matthews was being held in lieu of $100,000 cash bail or $200,000 bond after arraignment in Town of Potsdam Court.
