A Wichita minister says she is starting to become frightened by a growing number of death threats she has received since performing a wedding ceremony for 15 same-sex couples on the steps of the Sedgwick County Courthouse last month.

The Rev. Jackie Carter, pastor of the First Metropolitan Community Church, says some of the threats have been reported to police, but since the numbers of the callers don’t show up on her phone, she’s simply been told to “be careful.”

Carter told The Wichita Eagle someone called on Monday and she heard heavy breathing before someone rang the doorbell and someone else started throwing rocks at the windows.

She says the church has instructed people to leave the building in pairs, especially at night.
