Actor Bill Paxton died nearly a year ago on February 25, 2017, at age 61. His official cause of death was listed as a stroke, which he suffered 11 days after having heart surgery on Valentine's Day.

According to court documents cited by the Fort Worth Star-Telegram (Paxton was a Fort Worth native), the Paxton family has filed a lawsuit against Cedars-Sinai Medical Center in Los Angeles, and also against surgeon Ali Khoynezhad.

The family plaintiffs include Paxton's wife Louise, and children James and Lydia (all shown above in a photo from 2011). The lawsuit alleges that Dr. Khoynezhad "intentionally performed unnecessary heart surgery" on Paxton, and during that surgery "acted negligently and/or recklessly and provided harmful and/or offensive management and treatment," thereby causing Paxton's death.

The suit alleges that Khoynezhad was not in the operating room, or possibly the hospital at all, when Paxton suffered multiple complications; they claim the surgeon left "without arranging for continuous care and coverage ... and failed to timely return to the operating room upon notification of the complications, causing a delay in treatment resulting in damage."

You can read the family's full lawsuit here. The complaint for damages includes wrongful death, negligence, breach of fiduciary duty, battery, and survival action. The case includes a demand for trial by jury, with damages exceeding $25,000.

Paxton had wrapped all of his episodes for CBS's "Training Day" before he died. Paxton's son James guest starred in Episode 8, "Blurred Lines," which aired two months after his father died.
