BOSTON, Massachusetts (CNN) -- The mother of an abducted 7-year-old girl is using YouTube to beg her former husband to return the child.
Sandra Boss addresses her husband and her daughter in a message posted on YouTube.
In a video posted on the popular Internet site Thursday by the Boston Police Department, Sandra Boss speaks to her ex-husband, Clark Rockefeller.
She says they both love their daughter, Reigh, nicknamed "Snooks," and "have only her best interests and well-being in our hearts."
"I ask you now, please, please bring 'Snooks' back. There has to be a better way for us to solve our differences than this way," she says. Watch her emotional plea »
Rockefeller, 48, took his daughter during a supervised visit Sunday afternoon in Boston, Massachusetts, a social worker overseeing the visit told police.
The social worker said Rockefeller and the girl were whisked away in a black SUV that stopped beside them as they walked along a Boston street. Watch police describe the abduction »
Boston police say people have reported hundreds of possible sightings of the pair, but none had been verified.
On Friday, Detective Sgt. Calvin Chase of the Turks and Caicos Police Department told CNN that Rockefeller and Reigh had been seen twice Thursday on the islands, which are just north of the Dominican Republic at the southern end of the Bahamas.
Clerks at both an auto parts store and a convenience store identified the pair from photographs, Chase said, though they said the girl's hair had been cut short to resemble a boy's.
Boston police have issued an arrest warrant for Rockefeller, charging him with custodial kidnapping and assault and battery. The FBI is assisting in the case, they said.
Rockefeller and Boss divorced in 2007. Boss lives in London, where she is a partner with McKinsey & Co., a global management consulting company, The Times of London reported.
The paper said Boss was granted custody of Reigh. Although Rockefeller was allowed visits, they had to be supervised because Boss was concerned he would take the child. Sunday's visit was Rockefeller's first.
Boston police said Rockefeller may not be the man's real name. He has been known to use the aliases J.P. Clark Rockefeller, James Frederick, Clark Mill Rockefeller and Michael Brown, they said.
The Times of London reported that he told Boss he was a member of the wealthy Rockefeller oil family, related to industrialist John D. Rockefeller and his only brother, William, who co-founded the dynasty. But the Rockefeller family issued a statement Tuesday denying the man has any connection to the family.
