Not long after their marriage, Dana incurred a large amount of debt. At this time, she did not have much contact with her family due to a dispute over an aunt's will. She was a labor and delivery nurse at Inland Valley Regional Medical Center. They lived in the gated community of Canyon Lake where they had several business ventures under the name Graymatter. Gray left her husband in early 1993 and moved in with their friend and her lover, Jim Wilkins, and his young son Jason. In June, 1993, she filed for divorce from Gray, though this was not finalized until after Dana had been in jail for quite some time. In September 1993, she and Gray filed for bankruptcy to stave off foreclosure on their Canyon Lake house. Although the value of the house had greatly increased since they purchased it, they owed much more on the house than it was worth. On November 24, 1993, she was fired from the hospital where she worked for misappropriating Demerol and other opiate painkillers. On February 14, 1994, Dana sent word through Gray's parents (Gray kept his phone number and address hidden from her) that she wanted to meet with her estranged husband. Gray initially agreed but did not show up. Later that day, Dana murdered Norma Davis, an elderly lady whose home Dana had shared for a time. Gray later found out that Dana had taken out an insurance policy on him. The policy would have paid off the Canyon Lake house in the event of Gray's death. Norma Davis, 86, is thought to be Gray's first victim. Because of the lack of evidence Gray was never convicted of killing her. Norma was the mother-in-law of the woman (Jeri Davis) who married Dana's father, Russell Armbrust, in 1988. Jeri's first husband, Bill Davis, was Norma's son. Davis died in the early 1980s, and his widow eventually married Armbrust. Jeri continued to care for her elderly mother-in-law, even after she remarried. Dana knew Norma very well. On February 16, 1994, Norma Davis had been dead for two days when she was found by her neighbor, Alice Williams. Davis had a wood handled utility knife sticking out of her neck, and a fillet knife sticking out of her chest. Other than a broken fingernail, she had no other marks. A bloodied afghan lay at her feet. Detectives learned that there was no forced entry into the house.
