A LAWYER SHOT AT HOME, AND HIS GIRLFRIEND ADMITS SHE PULLED THE TRIGGER - IT LOOKED LIKE THE STORY WAS OVER, IT WASN'T - "48 HOURS" IS THERE FOR A NEW TRIAL AND A NEW VERDICT

Saturday, Dec. 29

A successful young attorney is gunned down in his own home. The shooter? His on-again, off-again girlfriend, a beautiful, young graduate student. She said it was self-defense. Police said it was something else.

It looked like the story was over. It wasn't. Peter Van Sant and 48 HOURS investigate what happened between Ryan Poston and Shayna Hubers on Oct. 12, 2012 and are there for a new trial and a new verdict in an updated encore of "Obsessed" to be broadcast Saturday, Dec. 29, 2018 (9:00-11:00 PM ET/PT) on the CBS Television Network.

At the time of his death, Poston was a 29-year-old self-employed lawyer. Hubers, too, was "very, very, bright," according to Highland Heights, Kentucky police chief Bill Birkenhauer.

What is certain is Hubers shot Poston. She admitted she shot him the moment she dialed 9-1-1. But what led to the shooting, however, is where the story takes unexpected turns. After the incident, Hubers was taken to police headquarters. There, she told police she wanted a lawyer. But then, unexpectedly, she began talking - on and off for more than two-and-a-half hours. With a police camera rolling, Hubers also danced, sang and snapped her fingers humming, "I did it! Yes, I did it." Portions of the video will be broadcast by 48 HOURS.

"If you go to jail, are you allowed to keep your phone?" Hubers asked later on the video.

"Someone who is in shock does not pirouette," says prosecutor Michelle Snodgrass. "Within six hours of putting six bullets into Ryan Poston and watching him die, she danced and sang."

"Shayna Hubers is not a murderer. No, she is not," says Hubers' mom, Sharon Hubers.

So why would she shoot him? Was it a breakup gone bad or something else?

Hubers was convicted of killing Poston in August 2015. But a year later, the case was thrown out over an unusual problem with the jury. 48 HOURS has the latest, including Hubers' retrial and more.
