A convicted felon found with more than 100 guns in his Fruitvale home during a raid won't be charged according to the Mesa County District Attorney's Office.

District Attorney Pete Hautzinger and Sheriff Stan Hilkey sent a letter to William Martin's attorney Friday morning telling her they would not be filing charges.

The letter states that even though Martin is a convicted felon, he was not fairly on notice of the criminal nature of his conduct when the weapons were removed from his home.

Colorado law states that police cannot release the guns back to Martin, but he can designate a person to pick them up.

Several of the guns seized were illegal, including one with a defaced serial number. The illegal guns will not be returned.

Martin said he's pleased he's not being charged.
