On Sunday afternoon, during a scheduled visit to see his son in Kent, Wash., Williams and the woman argued in the parking lot of her apartment building, where he exposed the gun and made verbal threats, she told  police .
The first-year Celtics guard’s father Edgar Williams and mother Sherry Jackson both spent time in prison, and his father was murdered shortly after his release from jail on drug charges in 1993, according to The New York Times  (h/t SI.com ).
The C’s signed Williams out of the Chinese Basketball Association to a series of 10-day contracts in February, and then inked him for the remainder of the season in early March. The deal included a non-guaranteed salary for 2013-14, when Williams was expected to compete for backup point guard duties behind Rajon Rondo .
He averaged 7.1 points (49.5 FG%), 1.8 rebounds and 1.6 assists in 13.3 minutes over 24 games for the Celtics this season. He appeared in five of their six playoff games against the Knicks, averaging 1.0 point, 2.0 rebounds and 1.2 assists in 9.6 playoff minutes a night.
When Sebastian Telfair  was arrested on gun charges soon after the 2006-07 campaign, Celtics co-owner Wyc Grousbeck disowned the former C’s guard  — announcing the removal of his nameplate from his Waltham locker in an email to The Boston Globe — and the team included him in the deal for Kevin Garnett  that summer.
That shouldn’t get your hopes up for a Kevin Love  deal involving Terrence Williams.
