  • His first wife Teddi Siddall died amid their divorce
  • Here's what's known about the tragedy

NCIS actor Gary Cole is a married man. He quietly tied the knot with wife Michelle Knapp in 2021. It was actually the second marriage for the star. But Gary Cole's first marriage ended a bit mysteriously.

Gary Cole: What happened with his wife Teddi Siddall?

Gary Cole, long known from movies like Office Space and Dodgeball, married the actress Teddi Siddall in 1992. The marriage lasted 25 years, but Siddall filed for divorce from Cole in June 2017, according to TMZ.

However, a few months after the divorce filing, Teddi Siddall passed away. She died at the age of just 64 in February 2018. And very little has ever come out about her death.

Gary Cole and Teddi Siddall had a daughter together, and she paid tribute to her late mother a few days after she died. On Instagram, Mary Cole wrote in part: "Mom you were my everything. Not only my mother but my best friend, rock and sun."

Elsewhere, a memorial page exists for Theodora Siddall Cole's gravesite in California. But her cause of death has never been confirmed, nor has Gary Cole ever commented publicly on the sad loss.
