Robert Harrod, 81, disappeared from his home on the 500 block of Carnation Drive on July 27, 2009, according to Placentia police. Although his body was never found, detectives believe he was the victim of a homicide. Two weeks before he went missing, KTLA interviewed Harrod about his unconventional love story: He had reunited with his high school sweetheart and, 60 years after he first asked her, they got married. His new wife, Fontelle, had lived back east and returned there to retrieve her belongings. Harrod went missing during her trip. Harrod’s daughter, Roberta, said he had been at home working on repairs with his son the day he disappeared. The son went to a hardware store to get some pricing, and when he returned Harrod was nowhere to be found — though his car remained in the driveway. Roberta said the family suspects a woman her father had loaned money and her husband could be tied to the killing. “He had helped her out with a large sum of money — about $50,000 in a six-month period,” Roberta said. Police do believe the killer’s motive was money. “Mr. Harrod had assets that basically made him a millionaire,” Sgt. Joe Connell told KTLA. “That’s always a factor in a case like this.” Two Placentia residents were detained as persons of interest last month, but both were released while authorities investigate further. Investigators said the two people that had been arrested had been on their radar for a long time. They declined to identify the pair, citing the ongoing investigation, but described them as “associates” of Harrod. Roberta is offering a $50,000 reward for information leading to the identity, arrest and prosecution of the perpetrator or perpetrators.
