A man whose body was found 120 feet down a Pasco County sinkhole last week was positively identified Sunday as an 85-year-old Port Richey resident who was last seen in March, sheriff's officials said. Fritz Geszti, who was found inside his 1986 Oldsmobile, was identified through dental records and a dental plate he had worn, according to Pasco County sheriff's spokesman Jon Powers. Cause and time of death are still being determined, but homicide has been ruled out, Powers said. Geszti's car was discovered last week by two people practicing night diving in the sinkhole named Palm Sink. The discovery prompted a two-day recovery effort.
