"We vetted this thing from A to Z," he said. "My only question was: Did these people violate the law?"
Rollins has said his office is going to review all its evidence and may hire another abortion expert to re-examine the place of termination of the fetuses.
If the state's attorney determines that the terminations occurred in New Jersey, similar charges are not expected there.
"There's no indictable offense in this state that fits what he was doing here," said Jason Laughlin, a spokesman for the prosecutor's office in Camden County, N.J., where Brigham's primary clinic is located.
In addition to New Jersey, Brigham controls abortion facilities in Pennsylvania, Virginia and Maryland. Though the Elkton facility has closed, three clinics remain in Maryland.
Brigham has never been licensed to practice medicine in Maryland. He was able to oversee abortions in the state by employing Maryland-certified doctors, like Riley. Though her license was suspended after the August 2010 procedure, she may have it reinstated after an administrative hearing.
Maryland's physician licensing board ordered Brigham to stop practicing medicine without a license.
But closing Brigham's facilities in Maryland is the only way to keep him out of the state, said Vicki Saporta, president of the Washington-based National Abortion Federation, a professional association of abortion doctors.
Dori Henry, a spokeswoman for Maryland's Department of Health and Mental Hygiene, said that until new regulations on surgical abortion facilities go into effect, there is little that agency can do to regulate Brigham's offices in the state.
State officials are now reviewing public comments on the regulations.
