Harvey was accused of egging on 42-year-old Bruce Hughes, Lott's boyfriend, as he beat her to death. A jury convicted Hughes of capital murder in February.
A third defendant, Amanda Jo Walters, said during Hughes' trial that the trio pretended to sell Lott crack so they could rob her. Walters refused to testify in Harvey's trial and was held in contempt of court.
Defense lawyer Frank Davila said he might appeal Harvey's sentence.
