CHICAGO, Illinois, July 23, 2012, (LifeSiteNews.com) - A 24-year-old Chicago woman died of hemorrhaging Friday night after obtaining a second trimester abortion at the Loop Health Center Planned Parenthood.

Tonya Reaves was pronounced dead at 11:20 p.m. after being transported to Northwestern Memorial Hospital.

While the medical examiner has ruled it an accident, the family is demanding answers.

“It happened so fast. She was just fine one day and then the next day she was gone. We’re just trying to figure out what happened,” her twin sister Toni told CBS Chicago.

Planned Parenthood of Illinois said they were “shocked and saddened upon learning of a tragic development at a nearby hospital,” but said they do not discuss private patient matters.

An autopsy conducted Saturday determined that she died from hemorrhage following a Dilation and Evacuation abortion. The D&E abortion method is one employed in pregnancies that have advanced beyond the first trimester. In involves opening the cervix and removing the pre-born baby by dismembering him or her. The Loop Health Center Planned Parenthood advertizes abortions up to 18 weeks.

While the name of the abortionist responsible for this patient death is currently unknown, Planned Parenthood’s most recent 990 tax forms list abortionist Caroline M. Hoke as its medical director.

This incident follows a report published in the Chicago Tribune in June 2011, that exposed the fact that some abortionists did not report complications at all, in violation of the law. At that time, Illinois officials made no attempt to enforce abortion laws in that state.

“Abortion deaths like this are completely avoidable,” said Troy Newman, President of Operation Rescue and Pro-Life Nation. “When a woman bleeds to death after an abortion, it is usually an indication of error on the part of the abortionist coupled with a delay in calling for emergency assistance. Planned Parenthood should be held accountable. Our heartfelt prayers go out to the victim’s family at this time of tragic loss.”

The abortion death took place in President Obama’s adopted hometown of Chicago at a time when his administration is working hard to provide funding to Planned Parenthood through the federalized health care system.

“In light of this tragedy, which is yet another in a long list of Planned Parenthood abuses, we call on President Obama to immediately withdraw all federal funding and personal support from Planned Parenthood,” said Newman. “Friday’s death is yet another reason why men and women of conscience across this nation cannot and will not comply with the forced funding of abortion and its intentional violation of religious liberties.”
