Noah Berger/For The Center for Investigative Reporting Crystal Nguyen, with her 6-year-old son, Neiko, in Pittsburg, Calif., is a former Valley State Prison for Women inmate. She worked in the prison's infirmary in 2007 and says she often overheard medical staff asking inmates who had served multiple prison terms to agree to be sterilized. By Corey G. Johnson Center for Investigative Reporting Publish date: July 8, 2013 Doctors under contract with the California Department of Corrections and Rehabilitation sterilized nearly 150 female inmates from 2006 to 2010 without required state approvals, The Center for Investigative Reporting has found. At least 148 women received tubal ligations in violation of prison rules during those five years – and there are perhaps 100 more dating back to the late 1990s, according to state documents and interviews. From 1997 to 2010, the state paid doctors $147,460 to perform the procedure, according to a database of contracted medical services for state prisoners. The women were signed up for the surgery while they were pregnant and housed at either the California Institution for Women in Corona or Valley State Prison for Women in Chowchilla, which is now a men’s prison. Former inmates and prisoner advocates maintain that prison medical staff coerced the women, targeting those deemed likely to return to prison in the future. Crystal Nguyen, a former Valley State Prison inmate who worked in the prison’s infirmary during 2007, said she often overheard medical staff asking inmates who had served multiple prison terms to agree to be sterilized. “I was like, ‘Oh my God, that’s not right,’ ” Nguyen, 28, said. “Do they think they’re animals, and they don’t want them to breed anymore?” One former Valley State inmate who gave birth to a son in October 2006 said the institution’s OB-GYN, Dr. James Heinrich, repeatedly pressured her to agree to a tubal ligation. “As soon as he found out that I had five kids, he suggested that I look into getting it done. The closer I got to my due date, the more he talked about it,” said Christina Cordero, 34, who spent two years in prison for auto theft. “He made me feel like a bad mother if I didn’t do it.” Cordero, released in 2008 and now living in Upland, Calif., agreed, but she says, “today, I wish I would have never had it done.” The allegations echo those made nearly a half-century ago, when forced sterilizations of prisoners, the mentally ill and the poor were commonplace in California. State lawmakers officially banned such practices in 1979. During an interview with CIR, Heinrich said he provided an important service to poor women who faced health risks in future pregnancies because of past cesarean sections. The 69-year-old Bay Area physician denied pressuring anyone and expressed surprise that local contract doctors had charged for the surgeries. He described the $147,460 total as minimal. “Over a 10-year period, that isn’t a huge amount of money,” Heinrich said, “compared to what you save in welfare paying for these unwanted children – as they procreated more.” The top medical manager at Valley State Prison from 2005 to 2008 characterized the surgeries as an empowerment issue for female inmates, providing them the same options as women on the outside. Daun Martin, a licensed psychologist, also claimed that some pregnant women, particularly those on drugs or who were homeless, would commit crimes so they could return to prison for better health care. .
