NEW DETAILS in the Murder of Tamara Tucker. Her boyfriend Eric Newman has been convicted of killing her during her birthday trip onboard a Carnival Elation cruise ship.
Years earlier, Robert McGill killed his wife on the Carnival Elation after drinking heavily. He said a scorpion inside the tequila bottle possessed him to kill.
55 year old McGill was celebrating his birthday with his wife of five years Shirley, and some friends on the Carnival Elation cruise to Mexico from San Diego.
Friends said that Robert McGill loved Shirley with "All his heart". He and Shirley were high school sweethearts who has reconnected and gotten married before their 30th Claremont High School reunion.
On July 14, 2009 McGill was drinking heavily in Cabo San Lucas. He reportedly drank half a bottle of tequila and a six pack of beer. After he boarded the ship passengers heard screaming coming from his stateroom.
We would later learn that McGill had beaten his wife and strangled her. Other passengers would find him on the upper deck smoking a cigar after the murder.
