CHARLESTON, W.Va. -- Annette Snow has no doubt that Charleston police will solve the slaying of her ex-husband, a likable 7-Eleven district manager with no enemies that she knew of.Next week will mark the one-year anniversary of the date boaters found the body of Robert Snow, 55, of 103 Arlington Ave., in the Elk River. Police and Snow's family are holding out hope for a break in the case, while his former employer is renewing a $10,000 reward for information in his death."We went out to the cemetery on his birthday and we are going back out on the date of his death," Annette Snow said Saturday. "We just went the other day, and my eldest son made sure his headstone is clean. We just beg him to tell us something."Robert Snow was last seen at about 5:30 p.m. May 23, 2012, inside the 7-Eleven on Bigley Avenue. He was supposed to attend a district manager's meeting that night in Kanawha City, but he never arrived.The next day, police found his gold Mazda Tribute and cellphone abandoned behind the Pronto Warehouse off Westmoreland Road. His body was found May 26, with clear indications of a struggle.Annette Snow said she's confident a break in the case will come soon. Charleston police detectives frequently update her family on their investigation, she said. Detectives are working multiple leads and never reveal too much, for fear of hindering their efforts, she said."I call them all the time and I'm the type that's waiting for them to say, 'shut up lady,'" she said. "They never have. That's why I have to believe in them."Police have said Robert Snow was a respected district manager of more than a dozen 7-Eleven stores in Kanawha County. His funeral was attended by many 7-Eleven employees and Snow's regular customers.Officials at 7-Eleven have renewed a $10,000 reward leading to an arrest in connection to his slaying, she said.So far, police have not developed enough evidence to pinpoint what happened to Snow. Even though he won $50,000 in state lottery prizes in 2011, police have said that they don't think Snow's killing was related to a robbery.Anyone with information is asked to call the Charleston Police Department's Criminal Investigation Division, at 304-348-6480.Robert Snow is buried in Arizona, where his two adult sons, Michael and Robert Jr., live. He recently had become a grandfather and got to meet his two grandchildren before his death."Our last memory of him is the week he was visiting us out here," Annette Snow said. "We just want it solved so bad."Reach Travis Crum at firstname.lastname@example.org or 304-348-5163.
