JACKSON, Miss. AP – A Mississippi Senate chairman on Thursday killed a bill that could have led to a homicide criminal prosecution for anyone performing an abortion once a fetal heartbeat is found.

Senate Judiciary B Committee Chairman Hob Bryan, D-Amory, said the bill is unconstitutional because lawmakers are limited in what they can do to restrict abortions in the first trimester of pregnancy under Roe v. Wade, the 1973 U.S. Supreme Court ruling that established a nationwide right to abortion.
