Los Angeles ? A one-time police garage attendant suspected of killing 10 people and stumping detectives for more than two decades was finally arrested Wednesday after police used DNA from his son to track him down.

Lonnie Franklin Jr., 57, was charged with 10 counts of murder, one count of attempted murder and special circumstance allegations of multiple murders that could make him eligible for the death penalty if convicted, District Attorney Steve Cooley said.

Detectives have spent years investigating slayings between 1985 and 2007 in which the killer targeted young black women and one man.
