The Grim Sleeper:

The grim sleeper is a California based serial killer with 10 kills (possibly more) attributed to his name.  The media given nickname was awarded to him on account of the 14 year gap between killings from 1988 to 2002.

Although he is awaiting trial on June the 30th, the accused is a 57 year old trash man by the name of Lonnie David Franklin Jr. His occupation is suspected to have aided him in the body disposal process as he is said to have dumped corpses at landfills.
