Four members of a Richmond, Virginia gun rights group were killed in a head-on collision Friday as the traveled to Detroit, Michigan, for an open carry rally.

Four members and supporters of a high-profile Richmond-area firearms rights group were killed in an early morning crash Friday near Dunkirk, Ohio.

Among those who died when their car collided with a tractor-trailer was Jason Spitzer III, the founder of The Right To Bear Arms RVA, a grass-roots group of Second Amendment supporters who are known for openly carrying their rifles and other firearms in neighborhoods and shopping districts. Stephen Kim and Jimmy Higgins were also killed in the crash, according to the Kenton Times. The Hardin County Sheriff’s office has not released the identity of the fourth crash victim.

The Right to Bear Arms RVA Facebook page identifies the fourth member of the group who was killed as David Alexander Armstrong. The page is also posting information on the vigils, funerals, and memorial services of the four men.

The men were going to be part of an open carry march with Detroit-based open carry group Hell’s Saints.

The collision remains under investigation.

We offer our condolences and prayers to the families and friends of those lost in this incident.
