One night, the musician drove to his mother’s Los Angeles home, took his hammer and struck the 71-year-old on the head four times. Osa Gordon crumbled to the floor but was conscious. Realizing this, Gordon then grabbed his knife and stabbed her four times in the heart. The matriarch died instantly. The Associated Press contributed to this report.

"Jim Gordon had long been deteriorating," author Joel Selvin told Fox News Digital. "He was really struggling to function. During this same period, he was playing in a band with a bunch of younger musicians. They had no idea something was wrong with Jim."
