2 things new to me:
"Mark Roessler, an IT manager, lived across the street from the house and told The Telegraph that Conditt and his father Pat bought the house about two years ago as a “fixer upper project”.
He described Conditt as “very polite” said he and his father worked together for about a year, before Conditt moved in.
“It was obvious the dad had a loving bond for his son,” said Mr Roessler. “He confided in me he was trying to build their relationship.
“Mark was quiet. He invited me into the house two or three times and I saw the remodel work.
“Mark moved in sometime last year and I haven’t seen much of him since. I would see people his age, males, come and go from the house.”"
And
"After completing his studies Conditt worked for several years at a local semiconductor manufacturer, Crux Manufacturing, before being fired last August for poor performance, according to local television station KVUE-TV.
The business' owner, who spoke to the television station anonymously, said Conditt "seemed like a smart kid who showed a lot of promise" and worked in purchasing and sales.
"He was very quiet and introverted, and did not have any confrontations with management," the owner said, adding that he was given several warnings for not meeting expectations before he was fired.
"
He would prioritize things in his own way.""
