A car found upside down in Nashua with a body inside is owned by a local woman who has been missing for more than two weeks, Nashua police said. After receiving a report of a vehicle seen off the roadway at about 3:30 p.m. Saturday, officers found the gray Saab on its roof amid “heavy vegetation” off Temple Street in Nashua, police said in a prepared statement. The car was registered to Sarah McCormack, 29, missing since June 26, police said. The body has not yet been identified. The New Hampshire medical examiner’s office will investigate the cause of death, police said.
