A woman who found her husband and another couple having a threesome and allegedly shot all three of them to death has been sentenced to 29 years in prison.

Crystal Gambino, 43, found her husband, Giovanni Gambino, 42, in bed with Geoffrey Glen Gilliland, 33, and Stephanie Lynn Sanchez, 33, in the North Carolina home she shared with her husband in February 2016. She then grabbed a .44 Magnum and a box of shells before killing all three, WYFF.com reports.

“We believe they were all three shot inside the house, in a bedroom, and then one of the victims, the female victim, was moved outside,” Gaston County Police Capt. Curtis Rosselle said.

Gaston County District Attorney Locke Bell said Crystal Gambino dragged Sanchez’s body outside to burn it, but she stopped after realizing she had to pick up her 8-year-old daughter from school, WSOCTV.com.

Investigators said there was no previous record of violence at the Gambinos’ home. Gilliland and Sanchez lived together in Charlotte, according to police.

Crystal Gambino had been charged with three counts of first-degree murder, but she pleaded guilty Monday under a plea deal to involuntary manslaughter in the death of her husband and second-degree murder in the deaths of Gilliland and Sanchez.

Prosecutors said Giovanni Gambino turned to Craigslist to find a couple to have a threesome with, even offering to pay them with cocaine, WSOCTV.com reports.

Eddie Hime, Sanchez’s father, said he wasn’t satisfied with the plea deal.

“Twenty-nine years for taking that away is not enough, in my opinion,” Hime said.

Gilliland’s sister, Jennifer Burke, showed pictures of her brother and displayed no remorse for Gambino.

“I can only hope that you suffer every day,” Burke said, adding that Gambino deserved many “sleepless nights” ahead for her while behind bars.

Gambino’s attorney, meanwhile, said the killings were the culmination of domestic violence, mental health issues and infidelity. She apologized to relatives of the victims, WSOCTV.com reports.

“I hate this happened. It’s a horrible tragedy, not only to these people, but to my family,” Gambino said. “I can say I’m sorry, but I don’t think they’ll accept it anyway.”

Police were called to the Gambinos’ home for a welfare check on Feb. 29, 2016. All three victims were found naked with gunshot wounds, the Charlotte Observer reports.
