A California fire captain will spend the rest of his life in prison after he was found guilty of killing his fiancée and her seven-year-old son over an argument sparked by a movie. 

Darin McFarlin, 47, was sentenced to two consecutive terms of life without the possibility of parole and an additional life term over the deaths of Marissa and Josiah Divodi-Lessa, the El Dorado County District Attorney’s office said on Thursday. 

McFarlin, a fire captain with the California Department of Forestry and Fire Protection, sat down to watch the movie ‘Fireproof’ with Marissa and her two young children at their home in Cameron Park on August 21, 2025, when the unthinkable happened, The Sacramento Bee reported. 

During the film, which is about a firefighter struggling in his marriage, McFarlin stormed out of the living room because he ‘became angry at the portrayal’ of the main character, the district attorney’s office said. 

McFarlin and Marissa later had a heated argument about the movie in their bedroom, which led the first responder to try to strangle her before she managed to escape and run out of the room.

In a rage, the murderous boyfriend grabbed his gun and followed Marissa into the living room, where her seven-year-old son and nine-year-old daughter would witness him execute their mother.

McFarlin shot his fiancée in the head in front of her children before turning the gun on little Josiah and fatally shooting him in the chest. He also threatened to kill the nine-year-old girl, Serafina, before she fled to get help.

The disgraced fire captain was charged with two counts of murder, as well as one count of attempted murder for threatening the little girl. He pleaded guilty to the crimes and received his multiple life sentences last Monday.

McFarlin’s victims were Marissa Herzog and her son, Josiah Divodi-Lessa. He shot the mother while the little boy watched before turning the gun on him. Herzog’s daughter was also in the room and saw everything, but McFarlin spared her 

The family of the victims said that Serafina suffered severe emotional trauma after witnessing the vicious murder of her mother and little brother. 

McFarlin had worked for Cal Fire since 2000, but he was fired shortly after his arrest. 

In court, El Dorado County Chief Assistant District Attorney Lisette Suder called the disgraced captain a ‘narcissist’ and said he cared more about his image as a firefighter than the lives of his fiancée and her children. 

The prosecutor said that McFarlin was set off by a firefighter being portrayed negatively in the movie the family had been watching on the night of the shooting. 

Suder said that during the argument in the bedroom, McFarlin demanded that Marissa admit the wife was responsible for the troubled marriage portrayed in the movie rather than the firefighter. 

Suder laid out the timeline of the shooting and explained that after the mother fled the bedroom and went to the living room, she threatened to call 911 but called her father instead.

When McFarlin entered the room with the gun in his hand, Marissa asked if he was going to shoot her, all while the father listened on the other end of the phone. The murderous boyfriend said yes, and the call abruptly ended.

Prosecutors said that McFarlin pistol-whipped his fiancée in the head, which prompted her to cry out for her children.

Josiah was shot in the chest but did not die immediately. When police found him, he was transported to a hospital where he succumbed to his injuries

The little boy and girl came into the room holding hands before McFarlin callously fired his gun into their mother’s head while they watched. 

He then shot the little boy in the chest, fatally wounding him but not killing him instantly. As he pointed the gun at Serafina, she begged him not to shoot her.  

He eventually told her to leave the house through a doggy door, and she hid outside in fear that he would chase her. The murderer gathered his things and left as well.

Officers with the El Dorado County Sheriff’s Office responded to reports of the shooting around 9pm, where they found Marissa dead and Josiah fatally wounded. The little boy was transported to a hospital, where he later died.

McFarlin fled the county after his double homicide. He was arrested by deputies the next morning in nearby Mono County, about a four-hour drive from the murder scene.

In court on Monday, family members of the victims shared heartbreaking impact statements. A letter written by Serafina, who was in school that day, was read out loud.

‘Ever since Darin killed my mother and brother JoJo, I have been really sad and in shock,’ the letter said. ‘I miss them every single day.’

McFarlin issued an apology during the proceedings and said: ‘I’m truly very sorry for what I did … especially to Serafina, and I will be held accountable for this.’

Moments after the apology, a family member of the victims shouted ‘Coward!’ from the gallery.
