Geauga County court records show the father of the teen who authorities say shot five students at Chardon High School on Monday had been arrested many times for violent crimes against women in his life, including Lane's mother...................................


The father, Thomas Lane Jr., was known to county authorities because of a series of arrests for abusing women in his life, court records show. It's not clear how much contact the father and son had.
But between 1995 and 1997, the boy's father and mother, Sara A. Nolan, were each charged with domestic violence against each other.
The father was later charged with assaulting a police officer and served time in prison after trying to suffocate another woman he married several years after his son was born, according to court records.
He held the woman's head under running water and bashed it into a wall, leaving a dent in the drywall, court records show.
But soon after he went to prison, the woman wrote a letter asking that he be released early.
