LONGMONT, Colo. -- The search is on for more than 100 guns stolen from the home of a dead man in Longmont.

Entire gun safes were taken from the home.

The man’s brother is now trying frantically to keep those weapons out of the hands of bad guys.

The Longmont Police Department said it has received the report of the stolen guns.

For days, Frank Dickinson has been trying to find out who stole the weapons from his brother’s home.

“What went through my mind is I felt violated," Dickinson said. "I mean nobody has the right to steal your property. Violated is probably the best word and I was extremely upset that’s for sure.”

Those guns belonged to 63-year-old John Dickinson, who died suddenly of a heart attack. He did not have a will.

Four large safes and stacks of Dickinson’s guns were stolen a few days after he died.

Frank Dickinson said he tried remove the bulk of the weapons from the home, but police said he had to wait 10 days.

Dickinson lived alone and Frank Dickinson said his brother had a renter in the basement who recently had to be evicted.

Frank Dickinson said the door to the basement had been forced open, and locks were changed after his brother's death.

Police have asked for a list of serial numbers of the guns.

Nearly 90 of them were purchased from Grandpa's Pawn and Gun.

“It’s very worrisome because we could be the victim of gun violence through these guns," gun shop owner Rod Brandenburg said. "Police could be victims. You guys could be victims out on the street cause whoever’s got these guns they didn’t go through a background check.”

Frank Dickinson is also afraid the guns will end up in the wrong hands and is collecting the serial numbers and plans on taking them to police next week.
