Michael Jace, who starred as a cop in FX crime drama The Shield, has been found guilty of murdering his wife.
A jury found Jace, 53, guilty of second-degree murder on Tuesday in the May 2014 slaying.
Jace's shot his wife April three times in their Los Angeles home.
The verdict came after a week-long trial in which Jace's attorneys argued their client had told detectives he'd merely wanted to inflict pain on his wife, not kill her.
Jace's camp was pushing for a manslaughter charge.
However, prosecutors argued Jace was upset because his wife wanted a divorce. They said he shot her in the back before taunting her and then shooting her in the legs, the AP reports.
The actor's 10-year-old son testified he heard his father tell his wife: "'If you like running, then run to heaven.'"
Deputy District Attorney Tannaz Mokayef said Jace also believed his wife was having an affair.
Mokayef said the potential sentence would be 40 years to life in prison.
Jace did not testify in his own defense.
The Shield ran on FX for seven seasons from 2002 to 2008. Jace also appeared in the films Planet of the Apes, Boogie Nights and Forrest Gump.
