SAN DIEGO (AP) -- San Diego police have ordered new DNA tests in the cold-case probe of a teenager's killing nearly 35 years ago.
KFMB-TV says investigators are revisiting evidence from the 1978 death of Barbara Nantais. The 15-year-old was found naked, beaten and strangled near a lifeguard tower at Torrey Pines State Beach.
Nantais and her 17-year-old boyfriend were camping on the beach when they were attacked. Jim Alt tells the station that he was knocked unconscious with a rock and log from a firepit.
Police also are investigating the killing of another teenager on the same beach six years later. Fourteen-year-old Claire Hough also was strangled.
There are similarities in the cases but police aren't sure whether they're linked.
