Lottery millionaire found buried in concrete

(CNN) -- Human remains found buried under recently-added concrete at a home in Plant City, Florida, are likely those of missing lottery millionaire Abraham Shakespeare, police said Thursday.

Deputies made the discovery after a tip came in, suggesting investigators would find a body near a home in Plant City, according to CNN affiliate WFTV.

Hillsborough County Sheriff David Gee said the body was slowly being uncovered. They are awaiting positive identification.

However, Gee said their investigation and information specifically led them to the area after they began to believe he might be dead because of "sinister means and motives."

Shakespeare, a 43-year-old truck driver, won a $31 million Florida lottery prize in 2006. A year later, he won a court challenge from a fellow trucker who accused Shakespeare of snatching the winning ticket out of his wallet while the two were delivering meat to Miami restaurants.

Shakespeare's family reported him missing on November 9, telling the Polk County sheriff's office they hadn't seen him since April.
