The husband of one of the three people killed by a white supremacist at two Jewish sites in suburban Kansas City has sued over the sale of the shotguns used in the April 2014 attack.

The lawsuit, filed late Monday afternoon in Jackson County Circuit Court by Jim LaManno, names Walmart and several other entities, The Kansas City Star reported.

Frazier Glenn Miller Jr., 75, of Aurora, was sentenced to death last year for the shooting that killed LaManno's wife, Terri, 53, at the Village Shalom retirement home in Overland Park, Kansas. William Corporon, 69, and is 14-year-old grandson, Reat Underwood, were killed at the nearby Jewish Community Center.

Miller was a felon and prohibited from purchasing guns. The lawsuit said Miller used two weapons that were purchased by friend John Mark Reidle: one at a gun show and the other at Walmart.

Reidle, also of Aurora, was sentenced earlier this year to five years of probation for falsely claiming he was buying one of the shotguns for himself on a federal form that was filed out at a Missouri Walmart just days before the shooting. Miller claimed the gun was a present for his son and asked Reidle to fill out the form, according to the plea agreement. Reidle told investigators that Miller asked for help with the purchase because he didn't have any identification with him.

Walmart didn't immediately respond to an email from The Associated Press seeking comment.

The suit also said Reidle and Miller attended a Springfield gun show in October 2013, where Reidle bought one or more firearms. Based on the men's remarks and behavior, the suit says, employees at Friendly Firearms LLC "knew, had reason to know, or recklessly failed to know that Miller was not lawfully entitled to purchase or possess a firearm."

The phone number for Friendly Firearms rang unanswered Tuesday morning.

Miller has said it was his duty to stop genocide against the white race. None of the victims was Jewish.
