An elderly Houston couple reported missing on Sunday were found safe in Florida, officials said.

A spokeswoman with the Harris County Sheriff's Office offered no more information Monday night about how Lorenza Gasca, 73, and her husband, Salomon Gasca, 78, were located.

Television station KHOU reported today that the couple took a wrong turn, then drove 524 miles before they were found at a gas station in Pensacola, Fla.

An officer who checked on the couple's license plates discovered a Silver Alert had been issued for them. Police then checked the Gascas into a motel, and a daughter was en route to Florida to get the couple, KHOU said.

Family members said both of the Gascas take blood pressure medication, and that Lorenza Gasca has Alzheimer's disease.

The couple went missing about 1 p.m. Sunday in the 21000 block of Oak Ridge Park in Houston after leaving a family get-together.

They were supposed to drive to another relative's home about a mile away but never arrived.
