(ABC 6 News) - Waseca authorities have charged three more people in connection with the John LaDue case. As we've reported, LaDue is accused of planning to kill his family then attack Waseca High School.

Police say one adult and two juveniles have been criminally charged with felony level crimes based upon information garnered in the John LaDue investigation.

Officials say 40-year-old Michael Jacobs admitted to selling a .45 caliber Llama handgun and magazine to Ladue in the Fall of 2013 for $350 and failing to advise law enforcement of the sale. According to the criminal complaint, Jacobs asked his son to "put out feelers" to find out if anyone wanted to buy a gun. But the document says Jacobs required a note from LaDue's father before selling to him. LaDue allegedly responded that the gun was for his father. Jacobs says he ended up selling the gun to LaDue because he needed the money.

Meanwhile, 17-year-old Austin Walters allegedly bought 15 pounds of explosive powder online for LaDue. Authorities identify the powder as potassium perchlorate. According to the criminal complaint, Walters helped LaDue make explosive devices known as "crickets" and,  along with LaDue, set some off at Oak Park in Waseca. The complaint says Walters also repaired another device made out of thermite and detonated it on an aluminum bench near the ball fields.

The other 17-year-old, Colby Radke, is also accused of helping LaDue build "crickets". The complaint says he and LaDue attempted to set them off at the local ball fields, but were unsuccessful. 

However, both juveniles say they were unaware of LaDue's alleged plan to kill his family and attack Waseca High School.

According to the criminal complaint, some of the latest information was discovered by LaDue's father. The document says, after police arrested his son, he asked some of his son's friends and their parents to have a meeting. It says that's when Walters admitted to buying the flash powder.
