Lonnie Franklin Jr., the suspect in the "Grim Sleeper" serial killings, is scheduled to be arraigned Monday morning in a Los Angeles, California, courtroom on 10 counts of murder.

Franklin is accused of killing 10 women in the south Los Angeles area between 1985 and 2007.

Nicknamed for taking long breaks between attacks, the "Grim Sleeper" is believed responsible for at least 10 deaths between 1985 and 2007 in south Los Angeles. The killer targeted black women, some working as prostitutes, using the same small caliber weapon.

Los Angeles police arrested Franklin on July 8 by comparing DNA found at some of the crime scenes with the DNA of the suspect's son, who was in a California lockup.

Five days after his arrest, Franklin was attacked in jail. Inmate Antonio Rodriguez and Franklin were in an attorney waiting room when the assault happened, said Steve Whitmore, a sheriff's department spokesman.

Rodriguez was not in handcuffs at the time and apparently recognized Franklin. Without being provoked, Rodriguez hit Franklin in the head twice, and he suffered minor injuries, Whitmore said.
