Ill Ratt

Ill Ratt was a member of the SPK. He also acted as a spy for Mello along with Halle Lidner. Ratt's real name was Shawn Dunleavy.

In How to Read 13, Takeshi Obata said that while designing the SPK members, he drew Ratt as being "suspicious looking" to further his character as a spy.

In the manga, after the founding of the SPK, Ratt walked outside their HQ and asked a citizen to borrow his phone so that he could inform Mello with information on the Death Note. A few years later, Ratt was briefly seen in a panel being ordered by Steve Mason to get John McEnroe to pick up Soichiro Yagami and his daughter Sayu, who was kidnapped by Mello and the Mafia as a trade for the Death Note. After Mello obtained the notebook, he used it to kill Ratt, along with most of the other SPK members, by making him commit suicide by shooting himself in the head with a gun. In the anime, he is not revealed to be a spy.
