Arraignment has been delayed for a Los Angeles man accused of the "Grim Sleeper" serial killings.

Lonnie Franklin Jr. appeared in court Tuesday to answer to 10 counts of murder and one count of attempted murder, but there was a change of public defenders and his arraignment was continued.

Superior Court Judge Hilleri G. Merritt set Aug. 23 as the new date.

Franklin was arrested July 7 at his South Los Angeles home. Police say DNA evidence linked the 57-year-old former city employee to the killings, which spanned 22 years.

The "Grim Sleeper" nickname came about because of a 14-year gap in slayings linked to the same killer. The most recent case was in 2007.
