Then, without warning, she vanished.
Today, police found a decomposed body near Robinson's South Daytona home. They haven't identified the remains, but her son feared the worst.
"Something bad is wrong," Fred Roberts said shortly before the body was discovered. "It doesn't sound good at all."
Roberts, 58, has been trying to reach his mother for about two months. A neighbor who lives across the street, Kimberly "Yaya" Smith, 44, told him Robinson had married a wealthy older man named Rusty and was on vacation in the Carolinas, he told police. She even sent him a photo of the newlyweds, marked "Just married, July 19, 2010" in a text message, an investigator's report says.
Police found an elderly man asleep on Smith's living-room couch. He looked like the man in the newlywed picture. He said he moved in with Smith and her boyfriend, David Enos, who were taking care of him after a stroke, a police report states. The man said he had seen Robinson several weeks before, but he was not her husband.
There are no Florida records of any recent marriage for Robinson, officers found.
During a search of Smith's home, police came across a disabled woman in a rear bedroom who told them Smith had informally adopted her, helps her with her money and takes care of her, the report states.
Police found the body, covered in a way police would not describe, in woods behind the mobile home Smith and Enos shared. A medical examiner will identify the body.
"It's highly suspicious," said Lt. Ron Wright of the South Daytona police.
Smith is serving 364 days at the Orange County Jail on a violation-of-probation conviction after being picked up by authorities earlier this month. She declined to be interviewed by the Orlando Sentinel. A woman identifying herself as the wife of Smith's son said the family had no comment and hung up on a reporter. A message left for Enos was not returned.
Roberts said he and his elderly mother were not always on speaking terms, and in recent months he'd kept up on her condition by talking to Smith.
He felt reassured when he learned his mother had a friend to take her to the mall, Walmart and the grocery store and make sure she took her medications.
"It made my heart feel good because this lady was watching out after her," Roberts said.
After the long silence, however, Roberts sent a few friends to his mother's mobile home on Saturday to look for her. They found it locked up tight with Robinson nowhere to be found. Roberts, whose name is on the title to the home, drove to Florida and got police involved on Sunday.
Robinson always kept a tidy home. But when Roberts went inside by jimmying a window, he found a mess: a slept-on mattress on the floor, full ashtrays, the carpet torn up, he said. Robinson has chronic obstructive pulmonary disease and high blood pressure and hasn't smoked in years, her son said.
Fresh groceries and children's toys also were inside, according to a police report.
"I can't describe the feeling I got when I walked in," Roberts said.
