There are so many unanswered questions I have. “Giannino told The Boston Globe on Wednesday that Anderson had ended her relationship with Davis months ago and he was not taking the break-up well, but the 23-year-old’s friends never thought he was capable of killing her.  Ali Giannino shared a photo of herself with Mary Anderson.

She wrote that Anderson had been “kidnapped” and a “Choose Life” license plate was removed from a family member’s car. When Anderson was found, she posted links to a memorial fund in her name.

In 2009, Davis was arrested after he snuck into the home of his ex-girlfriend — the father of his three children — and waited there overnight until she arrived with her new boyfriend, according to reporting in the Berkshire Eagle. Davis then stabbed the man, seriously injuring him, according to the Eagle.

The woman, who Insider is not naming, told the court at the time that Davis didn’t like her dating other men, even though they weren’t together. Dale Eason, who was a Pittsfield Police Detective at the time, testified in court that Davis was affiliated with an unnamed gang. Davis pleaded guilty to charges related to the attack, which included assault with intent to kill, and was sentenced to four to nine years in prison, according to court records obtained by The Globe.

He was released on parole in 2015, and completed it two years later, according to The Globe. According to the Justice Department, nearly, 15% of women and 4% of men in the US have been injured as a result of intimate partner violence, including rape, physical violence, and/or stalking by an intimate partner in their lifetime. Women between 18 and 34 have generally experienced the highest rates of intimate partner violence, according to the DOJ.
