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.

State authorities are investigating the death of 29-year-old Jennifer Morbelli, who passed away Feb. 7, just days after receiving an abortion from late-term abortion doctor Leroy Carhart.

An initial medical examiner's report shows she suffered from a "complication related to childbirth in which amniotic fluid was pushed into her bloodstream."

Now, the group Operation Rescue is seeking second-degree murder charges 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. She was not properly monitored. They knew it," Cheryl Sullenger, senior policy adviser for Operation Rescue, said.

Jack Ames, co-founder of Defend Life, said, "He left for Nebraska and later that evening she was bleeding profusely and she had to go to the nearby hospital."

Montgomery county police say their investigation into Morbelli's death "remains active" while they wait for the full autopsy report.

Pro-life groups also want the Maryland Board of Physicians to revoke Carhart's medical license. Some protestors recently stood vigil outside the building while the board met.

More than 1,300 people have signed a petition online, asking the board to take action.

Maryland medical examiner's office says a full autopsy report takes 60 to 90 days to complete.
