Von I. Meyer has been in police custody since Saturday, December 15, following threats of gunning down students and staff at an elementary school in Cedar Lake, Indiana.
According to the Daily Mail, police have found a record of 47 guns in Meyer's residence, when his wife let police know about his threats.
The 60-year-old man tried to intimidate her following an argument on Friday morning, by detailing several scenarios in which he would end her life. He first claimed he would set her on fire, and then went on to boast he would kill her "at the school."
According to the Huffington Post, Mrs. Meyer is a cafeteria worker at Jane Ball Elementary School, in the town located 45 miles (72 km) southeast of Chicago. The suspect burst out that he would "kill as many people as he could before police could stop him."
The suspect is a member of the Invaders Motorcycle Gang, which reached Northern Indiana in 1965. As officers searched his home, they stumbled upon the 47 weapons, and ammunition for said guns.
Many of them were collector's guns, and were hidden in different spots in the home. The Meyers lives in a two-story house in Cedar Lake, registered as a historic residence. The man's arsenal was valued at over $100,000 (€76,000).
"Through investigation, police learned that Meyer reportedly had a large number of weapons hidden throughout the two story historical home," their report reveals.
Investigators found that he could reach the elementary school, located just 1,000 feet (304 m) away from his home, by cutting through the neighboring woods.
He has been charged on 7 felony counts, four of which are for felony intimidation, two counts for resisting arrest, and one for domestic battery.
The threat came just one day after 26 children and adults were gunned down at Sandy Hook Elementary School in Newtown, Connecticut. Neighbors' accounts showed that the shooter's mother, Nancy Lanza, also killed on Friday, had taught her son, Adam, how to fire a weapon.
