Linda Curry suffered from a host of medical issues, but a doctor testifying for the defense says that she did not die of any health-related issues.

Nuclear engineer Paul Curry is on trial for allegedly injecting his wife with a lethal amount of nicotine in 1994 to collect over $500,000 from her life insurance policy.

While testifying for the defense, Dr. Steven Rosen said that Linda, who was 50 at the time of her death, was plagued with a number of medical issues, including gastrointestinal illnesses and depression, according to The Orange County Register .

"She had a long history of many complaints and multiple diagnoses," he told the Orange County Superior Court.

However, Rosen went on to acknowledge during cross-examination that none of these complaints led to Linda's death.

Deputy Public Defender Lisa Kopelman, who is representing Curry, has suggested that Linda may have taken nicotine to treat her gastrointestinal issues.

Curry's ex-wife, Leslie Curry, testified on Sept. 15 that she suffered from a mysterious illness during the final year of the couple's marriage.

"It wasn't until we split up that I started feeling better," she said. "It happened pretty quickly."
