SUMMERVILLE Authorities now say former pastor Dale Richardson kidnapped four women and raped three of them between January 2010 and July of this year.

Dorchester County sheriff's investigators say they will serve Richardson Thursday with warrants charging him with two counts each of criminal sexual conduct and kidnapping. He is already in jail without bail in connection with a July 27th kidnapping and rape incident and a June 21st incident in Summerville.

Investigators have been planning to charge Richardson with an Aug. 12, 2010 rape and kidnapping since last week. Maj. John Garrison said they recently found a third victim who was raped Jan. 5, 2010.

The woman told deputies she was hitchhiking on Rivers Avenue and Remount Road, trying to get a ride to a friend's house on Ashley Phosphate Road. A man in a Chevrolet S-10 with an extended cab and tinted windows, who called himself "Don," took her to a location on Mallard Road in Summerville and sexually assaulted her, Garrison said.

The January incident falls into a similar pattern as the later cases, in which the women were picked up in the Ashley Phosphate Road area and sexually assaulted them on the grounds of his Ladson church.

Summerville police say Richardson kidnapped a fourth woman but she was not sexually assaulted.
