On Friday, a Pima County jury found David Dwayne Watson, an ex-Tucson Firefighter, guilty of two counts of First Degree Murder and one count of Second Degree Murder.
In 2000, Linda Watson, Watson’s ex-wife, disappeared during a custody fight over their daughter. After Linda’s disappearance, her 63-year-old mother, Marilyn Cox, moved into her home and was involved in civil litigation with Watson, over unsupervised visitation rights with her granddaughter.
On May 7, 2003, Marilyn Cox and 53-year-old Renee Farnsworth were gunned down at Marilyn’s home after her first court ordered visitation with her grandchild, according to authorities.
Linda’s skull was found in 2003, and was identified as hers in 2011.
Watson was charged in April 2015. He pleaded not guilty.
In November 2016, a jury was unable to reach a verdict in Watson’s first murder trial after three days of deliberations.
Watson is scheduled to be sentenced on April 17, 2017, in Pima County Superior Court Judge Deborah Bernini’s Courtroom.
