A man and a woman were found dead at Camac Thoroughbred Horse Farm, owned by trainer Robert Camac, in rural Salem County, N. J. early Thursday, and while State Police haven't positively identified the bodies, a spokesman for the Salem County prosecutor's office said that both victims lived there, and were found on the rear porch of the farmhouse. Camac, 61, didn't show up at Barn 13 at Philadelphia Park Thursday, leading to strong speculation that the two victims were indeed he and his wife, Maryann.Police are calling the deaths a "double homicide," and were questioning workers on the farm.Camac, a Wilmington, De. native, has trained numerous stakes winners in his 40-plus career in racing, including Grade 1 winner Jolie's Halo, and Fire Plug, Cagey Exuberance and MATCH series winner American Champ. He won the Cotillion Handicap at Philadelphia in 1999 with Arthur Appleton's Skipping Around; he had a long and successful relationship with Appleton.In recent years Camac relocated his stable to Delaware Park in the summer, but always returned to Philadelphia each fall. Camac's uncles Joe and Charlie were both trainers; his nephew Chris Camac was the assistant to Delaware racing secretary Dan Eidson.
