He’s also suspected to be involved with other shootings that occurred in the area.

When Barrette was arrested, police discovered a .40 caliber loaded pistol and ammunition receipts in his home.

Barrette is being charged with two counts of first-degree murder, one count of second-degree murder, three counts of attempted second-degree murder, two counts of obstruction of justice and aggravated criminal damage to property.
