As police continue to investigate clinic terrorism, doctors are expressing concerns about testifying against legislation in the future.

Last year, doctors in Georgia expressed concern that they were being targeted after they had testified at the capitol in opposition to the proposed 20-week ban on abortion in Georgia.

Korotkin was set to testify at the same public hearing that Zane attended. Korotkin, who specializes in treating women with high-risk pregnancies, changed his mind about returning to the Capitol this year after his office received a deluge of threatening phone calls in the days leading up to the hearing. The calls stopped, he said, after he decided against testifying.

The FBI has released a sketch of a person of interest, but other than that has released no additional information about a suspect.
