Authorities say they plan to file terrorism and assault with intent to murder charges against the suspect in a weekend knife attack at a Walmart store in Michigan.

A nonprofit group called the SALT Coalition – an acronym for Spiritual Activists Leading Together – has organized an interfaith prayer vigil for those affected by Saturday’s extreme violence at a Walmart store in the up-north Michigan town.

An analysis of court records and archives found Bradford James Gille had a history of legal and mental health struggles before the July 26 attack.

Officials said the stabbings happened near the checkout area of the store and appeared to be random in nature.
