A Cincinnati mother was sitting in the passenger seat of a '90s-era Dodge Caravan being towed by a pickup truck when one of the two ropes pulling the minivan snapped, ripping off her arm below the elbow.
One rope was connected to the front of the van and the other was wound through the front windows of the vehicle. We're guessing it was the second rope that failed. (Hat tip to Yank_Boffin)
