Rollins went on to publish a two-part book series, the first book chronicling his time with Cole as his roommate, See a Grown Man Cry, and the second Rollins' non-stop working to near-nervous breakdown in the year following Cole's death, Now Watch Him Die.
Sonic Youth's "JC" was inspired by Cole's murder, and the Sonic Youth song "100%" on their Dirty album was dedicated to him. The music video shows a reenactment of the police finding Cole, played by actor Jason Lee, dead.
At the time of his death, Cole was in a relationship with Babes in Toyland bassist, Michelle Leon. After his death, she was unable to face the rigors of touring and quit the group. Peers of Babes In Toyland, Hole, also dedicated their second studio album, Live Through This, to Joe Cole. Courtney Love's 2006 memoir, Dirty Blonde, also features a page as tribute to Joe Cole.
Joe Cole can be seen in many scenes of Dave Markey's movie, 1991: The Year Punk Broke as well as in some of Dave Markey's short films.
Cole's father was actor Dennis Cole, and his stepmother Jaclyn Smith.
