3. LISA BROWN: NFL PLAYER’S MISTRESS KILLS HIS WIFE, THEN HERSELF

ELENWOOD, GA — On July 14, 2015, a love triangle between Buffalo Bills tight end Buster Barnett, his wife Sandra Barnett, and his mistress Lisa Brown went from out of bounds to full-on tragedy.

Brown, 49, reportedly incensed that Buster had been planning to take his wife on a vacation, blitzed the couple’s home with a gun, and forced Sandra off the phone and into a Dodge Durango.

The pair could not be located until the next day, when police spotted the SUV speeding on an Alabama highway. The pursuit culminated in horror. As one officer put it, “The driver stopped in the middle of the highway, pulled out a handgun, and shot [Sandra Barnett] and then turned the gun on herself.” [CrimeFeed]

4. ANN MARIE ANNASTASI: MOM ENLISTS DAUGHTER, 13, & BOYFRIEND, 18, TO KILL HER HUSBAND & THEIR MUTUAL FEMALE LOVER

LOTHIAN, MD — On October 5, 2015, Ann Marie Anastasi, 42, fatally shot her husband Anthony Anastasi, 40, and stabbed Jacqueline Riggs, his 25-year-old romantic partner — with whom Ann Marie also had a sexual relationship — in the house they all shared.

Ann Marie’s accomplices in the bloodbath were Sara Anastasi, her own 13-year-old daughter, and Gabriel Ezekiel Struss, the daughter’s 18-year-old boyfriend.

Initially, Ann Marie claimed that Anthony, to whom she was still married, had committed murder-suicide. The story crumbled amid mounting evidence, including text messages between the three conspirators in which they discussed Sara “taking the fall” because she’d only be punished as a juvenile.

Apparently, Mr. and Mrs. Anastasi had initially had a threeway relationship with Riggs, but Anthony ultimately opted to set up a basement apartment with Jacqueline rather than remain upstairs with Ann Marie.

In 2017, Ann Marie Anastasi entered an Alford plea. She got 60 years for the murders, plus five more on a weapons charge. [CrimeFeed]

5. SHANYA HUBERS: GETS DUMPED FOR BEAUTY QUEEN, SHOOTS BOYFRIEND

FORT MITCHELL, KY — Ryan Poston, 29, had some bad news for his on-and-off girlfriend Shanya Hubers, 24 (main photo, top), on October 23, 2012. He announced he’d be dumping her once and for all and, what’s more, he had a date lined up that evening with Audrey Bolte, that very year’s reigning Miss Ohio.

Poston didn’t make the date. Instead, Hubers blasted him in the head six times with a handgun, then called 911 and announced, “Ma’am, I killed my boyfriend!”

Hubers immediately claimed self-defense. It seemed fishy after she danced and snapped her fingers in the police interrogation room, and then asked if she’d be able to still have a cell phone in prison, saying, “I don’t know if anyone will ever want to marry me if they know that I killed a boyfriend in self-defense.”

On April 23, 2015, a court convicted Hubers of murder and sentenced her to 40 years. As a result, she is not, in fact, allowed to have a cell phone. [CrimeFeed]
