Michael Jace was found guilty of second-degree murder in the 2014 shooting death of his wife, April, in Los Angeles.
The former Shield actor was convicted on Tuesday after a weeklong trial. According to the District Attorney's office, jurors deliberated for less than three hours over two days to reach the verdict. The jury also found true an allegation that Jace personally used a handgun.
On Friday, Jace was sentenced to 40 years to life in prison. The sentence includes 15 years to life for the murder charge, and 25 years to life for the gun enhancement.
The prosecutor, Deputy District Attorney Tannaz Mokayef, told jurors that Jace was upset with his wife because she wanted a divorce.
Despite acknowledging that he killed his wife in the couple's Hyde Park home, Jace's lawyers fought for a voluntary manslaughter conviction as opposed to first-degree murder, arguing that the shooting wasn't premeditated.
Police arrested Jace on May 19, 2014, after he shot his wife with their two young sons (8 and 5 years old) present. After the shooting, Jace called 911 and told the operator he shot his wife. He also called and texted his father-in-law to pick up their children, who were not harmed.
