Defense attempts to discredit DNA evidence in Grim Sleeper trial

Prosecutors continued to press their case Wednesday that DNA evidence linking the deaths of several women to the man accused of being the “Grim Sleeper” killer was overwhelming.
That DNA evidence has been the focus of testimony this week in the trial of Lonnie Franklin Jr., who prosecutors say is responsible for a series of slayings in South Los Angeles spanning more than 20 years.
