Suspected Gilgo Beach killer charged with seventh murder
Suspected Gilgo Beach serial killer Rex Heuermann was charged with a seventh murder. Valerie Mack vanished back in 2000, and Heuermann was named a suspect in her death in June after prosecutors said a document referencing the site where her body was found was found on his personal computer. Now they say more evidence has linked him to the crime. NBC New York Greg Cergol reports.
