SANTA BARBARA, Calif. -- The father of a student who was gunned down in the May 23 rampage near the University of California, Santa Barbara has met privately with the father of his son's killer.

Richard Martinez told KEYT-TV he met Peter Rodger, the father of 22-year-old Elliot Rodger, at a Santa Barbara coffee shop on Sunday. He wouldn't discuss details of what he called a "private conversation between grieving fathers," but said they reached common ground and plan to work together.

Martinez has been an outspoken critic of the nation's gun laws since his 20-year-old son was shot by Elliot Rodger inside a deli. Five other UC Santa Barbara students were killed in the rampage, and police believe the killer took his own life at the end of the spree.
