Card, 40, a member of the U.S. Army Reserve who previously worked as a firearms' instructor, allegedly opened fire at a restaurant and bowling alley last Wednesday, killing 18 people and wounding 13 others.
A warrant was issued for Card's arrest on eight counts of murder, Maine State Police said Thursday. Following the suspect's death, local authorities rescinded the shelter-in-place order for neighboring communities.
According to the Maine Center for Information and Analysis, Card recently suffered from mental problems, which were accompanied by "threats of shootings at the National Guard base in Saco (Maine)." He is also on record as having spent two weeks in a mental health facility last summer before being released.
