GREER, S.C. - A man whose mother was one of three people killed in an unsolved bank robbery in Greer has made a video in hopes someone will call police with information to help crack the case.

Friday marks 11 years since 56-year-old teller Sylvia Holtzclaw, 60-year-old Eb Barnes and his 58-year-old wife, Maggie Barnes, were shot to death in a utility room in the back of the Blue Ridge Savings Bank on a road near Interstate 85.

David Holtzclaw posted a video on YouTube asking for help. He says his mother missed the birth of her first grandchild and her killer should be brought to justice.

Someone in the bank triggered a panic alarm, but there was no surveillance video or pictures from the building.
