Robert John Kirby of Palm Harbor died Wednesday from being shot Monday afternoon while he sat in the parking lot of the Village at Countryside nursing home. Pinellas County sheriff's spokeswoman Marianne Pasha said detectives still have no motive. "They're still puzzling over what would prompt someone to shoot someone at close range," she said. Kirby, 30, of 2768 Delaney Court, was shot at 4:40 p.m. at 1410 Fourth St. N in Safety Harbor. Detectives are looking for a suspect described as a clean-shaven black man in his 20s, 5 feet 10, and 145 pounds, who was driving a 1970s-model beige Buick LeSabre and might be carrying a shotgun.
