CHARLESTON, W.Va. (AP) -- Friends and families of victims of a West Virginia mine explosion have met to remember lost loved ones and seek justice.
Wednesday's gathering outside the Charleston federal courthouse commemorated the Upper Big Branch Mine disaster. Saturday is the four-year anniversary of the explosion that killed 29.
Massey Energy owned the mine and was later sold. Former CEO Don Blankenship released a documentary this week disputing his company was at fault. Victims' families say the film was like pouring salt in a wound.
They renewed calls to have Blankenship prosecuted. Blankenship's attorney has said his client has done nothing wrong.
Investigations found the blast was sparked by worn and broken equipment, fueled by accumulations of methane gas and coal dust, and allowed to spread because of clogged and broken water sprayers.
