But the sightings were investigated and found not to be credible, Boston Police spokesman Eddy Chrispin said.
"It definitely was not him," Chrispin said.
The girl's heartbroken mother, Sandra Boss, on Thursday made a plea on the internet for her safe return.
The videotaped statement read the following:
Clark,
Although many things have changed, you will always be Reigh's father and I will always be Reigh's mother.
We both love her dearly 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.
I also want to thank everyone for your help.
And Reigh, honey, I love you and miss you so much. Remember you're always a princess.

Rockefeller and his daughter were last seen at New York City's Grand Central Terminal on Sunday, hours after he allegedly ran off with her during a supervised visit. The girl has been living in London with her mother.
Police initially suspected Rockefeller was trying to flee to Bermuda or Peru on a yacht docked in Long Island. But authorities say he may have planted false clues to throw off investigators.
Many other reported sightings have been made, but none have panned out.
