When DNA Test Results Expose Shocking Family Secrets

DNA tests are not always done by choice. Sometimes they are done by force. In this case, Lonnie David Franklin Jr. also known as the Grim Sleeper, was a dangerous serial killer who had been identified through a DNA sample he had mistakenly made at one of his many crime scenes. 

The link came from his son who was forced by court order to give DNA evidence to prove he had committed a felony. Remember, all you need to complete a DNA test is a sample of saliva. Detectives obtained a sample of the suspect’s DNA from a leftover pizza slice.
