Parricide: The Act of Killing a Parent

Gross’ elderly mother was stabbed to death and police say the killer tried to stage a suicide. Gross says he has no reason to kill his mother, but detectives and the jury disagreed. The documentary explores Gross’ almost picture-perfect upbringing that took a violent turn when police say he started having financial troubles.

Teen Axe Killer

Seventeen-year-old Carlos Hallowell killed his adoptive mother, Denise Hallowell, with an axe in 2019. While charged as an adult, Hallowell wasn’t eligible for the death penalty because he was a minor when he plunged a full-sized axe into the back of his mother’s head as she slept. He tried to cover up his tracks by calling 911 and ditching the weapon in a nearby pond, but two years later, at the age of 19, a jury found him guilty of first-degree premeditated murder. Hallowell was given a sentence of life in prison without the possibility of parole. He is now 22-year-old and talked to NBC 6 exclusively.

The victim's mother also breaks her silence and responded to him. The crime generated international attention after Medina took a photo of the victim's body and posted it on Facebook. “When I published that photo, I didn't do it with cruel intentions,” Medina said. From prison, Medina told NBC 6 he killed his wife, Jennifer Alfonso, in self-defense. It’s the first time Medina, who is known as the “Facebook Killer,” talked exclusively to NBC 6 since he was sentenced to life in prison.

Negotiated Justice

Nancy Crowden was living her best life in Alaska in March of 2023 when a call from Miami-Dade Sheriff’s Office jolted her back to a time she’d rather forget. It was a night in January 1985 when she says two men she had just met in a Miami Beach bar raped her in a what was an open field along Northwest 9th Street west of Red Road. Within two hours of the attack, doctors collected DNA from her body that was eventually entered into a database that compares crime evidence to known offenders. Decades later, a DNA match led police to an arrest. Now the victim, Nancy, is sharing her story.

Behind the Door

NBC6 Investigator Amy Viteri uncovers details of a deadly police shooting inside a Miami Springs hotel that raised questions. The raid left 34-year-old Jaime Robles dead after a shooting witnessed by his two young sons. Less than 24 hours earlier, a Miami-Dade Police detective, Cesar Echaverry, had been shot during a confrontation with an armed robbery suspect, Jeremy Horton. Both men died from their injuries.

Finding Carlesha

In 2014, Carlesha Gaither Freeland was walking home from the bus stop when a man stopped her to ask for directions. That man then grabbed her and pulled her down the street. As she kicked and screamed, he pushed her into his car and drove off. Police may have never known a woman was abducted — or even who she was had it not been for an unlikely witness.

In “Finding Carlesha,” viewers get a behind the scenes look at the race to find her, starting with the moments before she went missing, the people involved and the frantic search for clues Carlesha was leaving behind across state lines. We retrace the path Carlesha’s abductor took during those three days, including a 300-acre farm in Maryland, the strip mall where an ATF agent found the kidnapper’s vehicle, and the town in Virginia where the kidnapper had abused and nearly killed a 16-year-old girl just two weeks before he abducted Carlesha.

We tell the story from various points of view, including Carlesha herself. She tells us her story of survival, hope and forgiveness. The documentary brings together people of different walks of life, all in an effort to save a young woman.
