PROVO -- Prosecutors will wrap up their case Tuesday in the murder trial of a Utah doctor charged in his wife's death.
The state is calling a pair of investigators and a cast of Martin MacNeill's former cellmates as its final witnesses.
MacNeill was in federal prison on fraud charges when prosecutors say he told inmates his wife was a "bitch" and that he was glad she was dead. They also say MacNeill boasted that authorities couldn't prove he killed her.
Defense lawyers say the inmates never heard the 57-year-old MacNeill actually confess.
Prosecutors are trying to persuade jurors that MacNeill knocked out his wife with painkillers and other drugs after insisting that she get a face-lift, then left her to die in a bathtub in 2007.
