Former Plantation Councilman Ralph Merritt and his wife Gloria died Thursday in what police said preliminarily appears to be a homicide-suicide. The Merritts “were suffering from health problems,” said Det. Robert Rettig, a Plantation Police spokesperson. The couple was found dead at a home in the city Thursday morning, he said. Rettig said detectives are actively investigating. The city’s post on Facebook, shared about 7:30 p.m., did not provide additional details about their deaths. “The family asks for privacy at this time,” the city’s post said.
