'Homicide for the Holidays' Season 4 Preview: How, When To Watch

On Saturday, Season 4 of Oxygen's "Homicide for the Holidays" will make its debut. The hour-long episodes will each examine a "devastating case as police investigate and go to incredible lengths to unveil secrets about the true motive of the killer, giving families justice about their loved ones' death," per the Oxygen site.

A preview for the new season can be seen below.

Season 4 will tell four unique stories. The first episode, which is called "Thanksgiving Terror," focuses on the murder of a mother while she is driving her sons home from a Thanksgiving dinner. Over the course of the investigation, law enforcement officials realize that the crime may not be "as random as it once seemed."

The next episode, which is titled "Last Christmas," is set to air Dec. 14. This installment follows the story of a young couple who is murdered inside their home. As they were recent additions to the neighborhood, police wonder how they could have made such an enemy so quickly. However, they eventually discover "deeply personal details" that expose an important secret.

Viewers can catch the third episode, "Christmas Heartbreak," on Dec. 21. After a couple is found murdered inside their home on Christmas morning, investigators have only a palm print to use as they begin following the clues to find the person who is responsible for the crime. As they go about working the case, they receive a letter from prison that "takes the case on an unexpected course."

Finally, on Dec. 28, the last episode in the new season premieres, which is called "Death in Santa Claus." A family is found massacred at their Santa Claus, Georgia home, which inspires a manhunt. Ultimately, police rely on the eyewitness of three young survivors to find out who was behind the horrific events.

The "Thanksgiving Terror" episode of "Homicide for the Holidays" will premiere Saturday at 7:30 p.m. EST on Oxygen.
