Fifty-two-year-old Tracy Edwards and 44-year-old Timothy Carr are accused of arguing with Johnny Jordan, picking him up and throwing him off a downtown Milwaukee bridge on Tuesday.
In July 1991, Tracy Edwards escaped from Dahmer's apartment, a handcuff still dangling from his wrist, and led police to him.
A criminal complaint filed Friday says that after the 43-year-old Jordan went in, Carr jumped in from the riverbank. Police later got Jordan and Carr out of the water.
The men's attorneys couldn't immediately be located Friday.
Edwards' address is listed as a Milwaukee homeless shelter.
