The Aliens star, 61, passed away last month (Feb17) after suffering complications following surgery.

Now medical officials have ruled his death was triggered by an aortic aneurysm, for which he underwent valve replacement surgery on 14 February (17).

He began experiencing health issues related to the operation days later, and passed away at Cedars-Sinai Medical Center on 25 February (17), following a stroke.

The death certificate, obtained by TMZ.com, also reveals Paxton was laid to rest at Forest Lawn Memorial Park just days after his passing.

The married father-of-two was also known for his roles in films like True Lies, Twister, Apollo 13, and Titanic, and he appeared in TV projects including Big Love, Hatfields & MCCoys, and the new small screen adaptation of Training Day.
