Anderson Cooper -- Christopher Dorner Sent Me Bullet-Riddled Coin

Before his shooting spree ... Christopher Dorner sent CNN anchor Anderson Cooper a parcel, containing a note, a DVD, and a coin riddled with bullet holes -- so says Cooper.

Cooper just tweeted about the package, saying he only learned today the package was sent to him.

According to CNN, the package was delivered to Cooper's assistant on February 1st -- and contained a hand-labeled DVD with a sticky note that read "I never lied." Wolf Blitzer said the note appeared to refer to when Dorner was fired from the LAPD in 2008.

It also contained a coin wrapped in duct tape, which was inscribed with "Thanks but no thanks, Will Bratton." Bratton served as the LAPD Chief until 2009. The coin was also inscribed with the initials "IMOA," which typically stands for "Imagine a More Open America."

The coin -- reportedly given by the LAPD as a souvenir -- was riddled with bullet holes.

As we reported, Dorner posted a rambling message on his Facebook shortly before his alleged shooting spree, in which he's accused of killing three people, including one police officer.
