Joseph Yania, a coal strip-mine owner, and Boyd Ross visited a coal strip-mining operation owned by John Bigan to discuss a business matter with Bigan. On Bigan’s property there were several cuts and trenches he had dug to remove the coal underneath. While there, Bigan asked the two men to help him pump water from one of these cuts in the earth. This particular cut contained water eight to ten feet in depth with sidewalls or embankments sixteen to eighteen feet in height. The two men agreed, and the process began with Ross and Bigan entering the cut and standing at the point where the pump was located. Yania stood at the top of one of the cut’s sidewalls. Apparently, Bigan taunted Yania into jumping into the water from the top of the sidewall—a height of sixteen to eighteen feet. As a result, Yania drowned. His widow brought a negligence action against Bigan. She claims that Bigan was negligent ‘‘(1) By urging, enticing, taunting, and inveigling Yania to jump into the water; (2) By failing to warn Yania of a dangerous condition on the land; and (3) By failing to go to Yania’s rescue after he jumped into the water.’’ Was Bigan negligent?
