A Stratford man will serve 20 years in prison for the fatal stabbing of his longtime girlfriend.

Stanley Mulvey, 68, appeared at the Bridgeport Judicial District Courthouse on Tuesday for his sentencing in the death of 62-year-old Megan McShane.

McShane’s sisters did not hold back as they addressed Mulvey face-to-face in court.

“Megan craved love and always cared for broken things. She was, unfortunately, the perfect mark for a virulent narcissist,” Kaitlyn McShane stated. “You will always be nothing and nobody, just a hateful, bitter, harmful man so envious of beauty that you beat and killed a woman just for talking too much. You deserve nothing but to be eaten alive by wolves.”

Mulvey was initially charged with murder and interfering with police but pleaded guilty to a reduced charge of first-degree manslaughter in exchange for a 20-year sentence.

Stratford police responded to the couple’s Griffen Street apartment on Oct. 20 after Mulvey called 911 on himself and confessed to killing Megan McShane. Police said they found him lying on top of his dead girlfriend with a large kitchen knife nearby. Once taken into custody, police say Mulvey continued to confess repeatedly that night.

The police reports said Mulvey was crying and quoted him as saying, “I can’t believe I killed my girlfriend,” “I can’t believe I did it,” “My baby’s dead,” and “Oh my baby, I’m sorry.”

During an interview with police, Mulvey said he and McShane had been drinking alcohol throughout the day, and while in bed, McShane was “babbling on and on and on,” interrupting his ability to watch TV, so he started “hitting her on the bed and telling her to shut up,” one report said.

Mulvey said McShane then got up and started “dancing around the house,” which is when he grabbed the knife on his nightstand and began threatening to kill himself, according to the report. Mulvey told police McShane ran out of the house, and when she returned, Mulvey was still holding the knife and “she accidentally ran into him and was accidentally stabbed in the abdomen,” according to the report.

“She ran into the knife, and then I stabbed her after that. I knew the stab was gonna do her, one way or the other,” the report quoted Mulvey saying. “She stayed alive for about 10 to 15 minutes. And I was just holding her wounds and kissing her and telling her how much I loved her.”

At Mulvey’s sentencing, McShane’s family talked about how they’ve been impacted by her death.

“The trauma of losing our sister in such a violent way is something we carry with us every day. It does not go away. It does not get easier. You learn to live with it because you have to,” said McShane’s sister Paula Piro. “We respectfully ask for the defendant to spend the rest of his life in prison, not because it will heal our pain—it will not. But because it will ensure that he can never harm another person or another family again. Our sister deserved a full life. She deserved more time, more memories and more love, and that was taken from her and from all of us.”

Mulvey has an extensive criminal history, including prior domestic violence convictions involving McShane.

Kaitlyn McShane read a statement from McShane’s adult son, Justin DiCosola, who wrote that for almost his entire life, he’s lived with "a knot in his stomach" regarding his mother’s safety and what Mulvey was capable of.

“That wasn't a sudden tragedy. It was a slow-motion disaster that I saw coming and that the state of Connecticut should have seen coming, too,” DiCosola wrote.

The statement said his mother was a woman who believed in mercy and second chances, “even for her own abuser,” and that he was choosing to forgive Mulvey for her.

“If I stand here and only give you my rage, then you have won. If I let the hatred that I have felt for you for decades consume me, then I am not honoring the woman she was,” DiCosola wrote. “I am choosing to be like her. I am choosing to be graceful and eloquent even in the face of this infinite pain. I am releasing the resentment so I can hold onto her love. I am choosing peace so that her spirit can finally have peace. You took her life, but you will not take the man she raised me to be.”

Mulvey got emotional as McShane's family spoke. He apologized to them in a letter read by his attorney, Assistant Public Defender Kelly Billings.

“I know you must hate me, but no one hates me as much as I hate myself,” the letter read. “Alcohol has been a problem my whole life. If I was sober, I know in my heart, I would never hurt my baby girl, let alone kill her.”

The letter called McShane the love of his life and said Mulvey cries himself to sleep nightly.

“I pray each night that the Lord take my soul and let me join Megan for eternity,” Mulvey wrote.

In handing down the sentence, Judge Shari Murphy acknowledged that no amount of time can ever make up for the victim’s family’s loss. Murphy said she believes 20 years meets the family’s request for a life sentence because at Mulvey’s age, he will likely die behind bars.

Mulvey also appears to have health issues. He needed a walker to get in and out of the courtroom, as well as to stand.
