(a) A person commits the crime of receiving stolen property if he intentionally receives, retains or disposes of stolen property knowing that it has been stolen or having reasonable grounds to believe it has been stolen, unless the property is received, retained or disposed of with intent to restore it to the owner.
(b) If a person:
(1) On two separate occasions within a year prior to the commission of the instant offense of receiving stolen property is found in possession or control of stolen property; or
(2) Possesses goods or property which have been recently stolen; or
(3) Regularly buys, sells, uses or handles in the course of business property of the sort received, and acquired the property without making reasonable inquiry whether the person selling or delivering the property to him had a legal right to do so, this shall be prima facie evidence that he has the requisite knowledge or belief.
(c) The fact that the person who stole the property has not been convicted, apprehended or identified is not a defense to a charge of receiving stolen property.
