Leo Kenneally was the owner/operator of the notorious Her Medical Clinic in California. He performed the fatal abortion on Lilliana Cortez. After her death, and the deaths of Michelle Thames and Maria Soto, and a complaint from a local hospital flooded with botched abortion cases, the state moved to shut Kenneally's facility down. Kenneally instead legally closed the facility and re-opened it as his private office, which would not have to be licensed by the state. Donna Heim later died there. Keneally also botched abortions at Inglewood Women's Clinic. (Scroll to the bottom.)
By "Helen's abortion" I assume the searcher wants information about the patient named Helen featured in the old Frontline show about abortion, rather than about Helen Clark, who died in 1941 after a criminal abortion performed by a blind lay abortionist; Helen Roe, who died after an illegal abortion by Annas Witlow Brown; Moris Helen Herron, who died of peritonitis after a safe and legal abortion in 1983; Helen Koss, who died from an abortion performed by a Chicago midwife in 1924; or Helen Bain, who died in 1924 after an abortion by Dr. George Slater.
Kevon Walker is the 21-year-old man charged with getting a 14-year-old girl pregnant three times in six months. The first of the three resulting abortins, Walker said, was the girl's mother's idea. Fat lot of good it did, Mom, to get her vacuumed out without getting the guy who got her pregnant arrested! It bewilders me that prolifers are supposedly the ones obsessed with fetuses, when there are evidenly plenty of prochociers who are equally obsessed, if not more so; it's just that they think that killing fetuses solves everything.
