Pro-life groups in Maryland are hoping state regulators will revoke an abortionist's medical license and file murder charges after a patient under his care died, CBN News reports. State authorities are investigating the death of 29-year-old Jennifer Morbelli, who died Feb. 7 just days after receiving an abortion from late-term abortion doctor LeRoy Carhart. An initial medical examiner's report shows Morbelli suffered from a "complication related to childbirth in which amniotic fluid was pushed into her bloodstream." The pro-life group Operation Rescue is seeking second-degree murder chargers against Carhart, saying Morbelli's family was unable to reach him as her condition worsened -- and that he in fact had left town. "There was no one for the family to contact when her condition began to deteriorate back at the hotel," said Cheryl Sullenger, senior policy adviser for Operation Rescue. "She was not properly monitored. They knew it." Jack Ames, co-founder of Defend Life, added, "[Carhart] left for Nebraska and later that evening she was bleeding profusely and she had to go to the nearby hospital." Pro-life groups are also calling on the Maryland Board of Physicians to revoke Carhart's medical license. Some protesters recently stood vigil outside the building while the board met, and more than 1,300 people have signed an online petition asking the board to take action. Police say their investigation into Morbelli's death "remains active" while they wait for the full autopsy report, which takes 60 to 90 days to complete.
