March 11th 2017 – 14-year-old Arden Summers drives her younger siblings back to her mother's home, following her dad’s secret orders. Hours later, an employee of a nearby Walgreens calls 911 after seeing a tied up woman run out of a car: the woman is Alisa Mathewson – Arden’s mom. Before the police can arrive, the car drives away with Alisa. Nobody knows where they are heading to, and with who, but Arden, who is home alone with her other siblings, might be able to solve the case in time.

It’s 1981 in the sleepy town of River Oaks, Texas, and someone is hunting cheerleaders. A 16-year-old teenager, Susan Brown, is brutally attacked in her own home. What she, the cops, and the rest of the town don’t know is that she’s just the first victim in a rampage that will change this Texas suburb forever. One by one, members of the Castleberry High School cheer squad are targeted, but things escalate when Rona Stratton’s sister is found dead in her bedroom. Rona decides to team up with her friend Lisa Ticknor, who also survived an attack, along with the other cheerleaders in the squad, to start a decades-long fight to take down the Cheerleader Slayer, and make sure he would never hurt anyone else.

Ominous voicemails, private investigators, secret cameras, Jessica & the detectives discover nothing is as it seems, and it’s up to them to trap the killer who thought he was too smart to ever be caught, and get justice for Patrick.

In 1979, 4 year old Jennifer Carson comes face to face with one of the most bizarre and deranged serial killers to have ever lived: none other than her new psychic step-mother, Suzan Carson. Suzan, along with Jenn’s father Michael Bear Carson, will embark on a years-long religious mission to hunt down and kill anyone they deem a witch, and Jenn is their first target. Little do the infamous San Francisco Witch Killers know that Jenn will escape the clutches of their evil cult and lead the way to justice for her and the rest of their victims.

In the early hours of March 10th, 2017, police officers enter the home of Valerie McDaniel and Leon Jacob with seemingly unexpected news – cops tell the new couple that Valerie’s ex-husband has just been killed in a robbery gone wrong, but there’s something else they’re hiding. What Leon and Valerie don’t know is that they’ve walked right into a trap—one designed to catch them in their own deadly scheme. Behind it all was the last person they expected: Leon’s ex, Meghan Verikas.

On February 23rd, 2023, in Quincy, Illinois, mom of 3 Becky Bliefnick was found dead, shot 14 times in cold blood, and despite the brutal nature of the attack, there isn’t any DNA evidence left behind. The killer thinks he’s outsmarted everyone, but little do they know that Becky refused to be a silent victim, and has left all the clues investigators need to uncover the truth and bring justice for her and make sure her killer would pay for the murder, and that her ex-husband Tim Bliefnick's true personality would be revealed, starting with an episode of Family Feud.

Becky’s sister, Sarah, has started a GoFundMe to create a scholarship fund and support Becky’s 3 young children. To donate, please click here.
