Authorities are looking for the middleman who purchased the guns used in last Sunday’s deadly suspected hate-fueled shootings near Kansas City.

Avowed racist and anti-Semite F. Glenn Miller couldn’t legally own guns because he is a felon.

Investigators believe the 73-year-old had help in obtaining the guns that he is accused of using to shoot three people outside a Jewish community center and the Village Shalom retirement home in Overland Park, the Kansas City Star said in Friday’s editions.

The Star quotes a law enforcement source as saying that investigators tracing the source of the guns think they were purchased by a straw buyer. Background checks would have tripped-up Miller, but not a go-between.

The source told the newspaper local police, the FBI and agents from the U.S. Bureau of Alcohol Tobacco and Firearms and Explosives are looking for the straw buyer.

The source told the Star the guns were purchased from a licensed merchant. But the source declined to say if authorities knew who the merchant was or determined when they were purchased.

Miller served time in federal prison after pleading guilty in 1987 to possession of a hand grenade in a case involving a white supremacist group.

He faces charges of capital murder and first-degree murder in the shooting deaths of Dr. William Lewis Corporon, his 14-year-old grandson, Reat Griffin Underwood, and Terri Lamanno. The shootings took place a day before the start of Passover. All three victims were Christians.
