Moore had made several attempts to make it look as though Shakespeare had been communicating with his family -- offering someone a $200,000 house in exchange for reporting a false sighting, sending his son $5,000 in cash for his birthday and sending text messages -- even though Shakespeare had already disappeared, Polk County authorities said.
Prosecutors are also expected to call Gregory Todd Smith, an informant to authorities, to the witness stand. According to investigators, Moore asked for Smith's help to conceal the killing.
According to Smith and official documents, Moore asked Smith whether he knew anyone who would take a murder rap for a $50,000 pay off, ABC News affiliate WFTS-TV reported.
Smith said for months he lived a double life as he worked with Polk County investigators to find Shakespeare's body and it finally paid off when Moore allegedly took Smith and an unidentified man to where the lotto winner was buried, according to WFTS.
The trial is expected to last two weeks and prosecutors are not pursuing the death penalty. If convicted, Moore faces life in prison.
