August 13, 1986: Safe and Legal in Los Angeles

Donna Heim, a 20-year-old nursery school teacher, went to Her Medical Clinic on August 12, 1986, accompanied by her sister. Donna told staff that she had asthma, and she noted this on her forms when she filled them out. Despite this pre-existing condition, a nurse anesthetist administered general anesthesia for her safe and legal abortion. Donna started to have difficulty breathing, but Mahlon Cannon continued with the procedure for five more minutes before helping the nurse anesthetist to try to restore Donna's breathing.

Donna's sister, who was in the waiting room, became alarmed at the intense staff activity she noticed, and questioned a staffer about her sister. She was reassured that Donna was fine. The sister saw an ambulance pull up to the building and stepped outside, where she observed her sister being transferred into the emergency vehicle. Donna's sister followed the ambulance to a nearby hospital, which summoned the comatose young woman's parents.

Donna died the next day without regaining consciousness. An investigation was sparked, and an administrative law judge ruled that Cannon was negligent in continuing with the abortion despite the patient's respiratory distress. The judge also found that Cannon often failed to do medical exams, take medical histories, or administer standard tests prior to abortions.

Donna's father, Richard Heim, told the Sacramento Bee, "I honestly thought that within a month or two the man would be in prison for manslaughter. When you go to the cemetery to visit your daughter, there's no way you can explain that, and this guy's just kicking back and making more money."

Donna's mother, Barbara Heim, told the Daily News of Los Angeles County, "I thought they'd close the door so no one else would die." But a month after Donna's fatal abortion Liliana Cortez, another woman with asthma, also died after an abortion at Her Medical Clinic. Michelle Thames would die at Her Medical Clinic in 1987 after being improperly resuscitated.
