Stan "Tookie" Williams was a founding member of the LA street gang the Crips back in 1971 at the age of 17. He was convicted in the 1979 shotgun murders of 4 people - 63 year old Tsai-Shen Yang, her husband Yen-Yi Yang, 67, and daughter Ye-Chen Lin, 43, during the robbery of a motel they owned.

He was also convicted of murdering 7-11 store clerl Albert Owens, 19, during a robbery where he apparently mocked the gurgling sounds made by Owens as he lay face down on the ground dying after an execution-style shotgun blast to the back of his head.
Wow, this is a hard one to call
