An accused killer, who Stratford police said called 911 on himself, was arraigned Wednesday in his longtime girlfriend’s death. Stanley Mulvey, 67, made his first appearance on charges of murder and interfering with police in the deadly stabbing of 62-year-old Megan McShane.

Paula Piro, one of McShane’s older sisters, was in the courtroom and began to cry as soon as Mulvey was led in.

“She was very good person. She didn't deserve to die like this. She didn't deserve to die at all,” said Piro emotionally after the hearing.

At Mulvey’s arraignment, Supervisory Assistant State’s Attorney Sean McGuinness said the strength of the state’s case is “particularly overwhelming.”

“The defendant actually called 911 and admitted to stabbing his girlfriend,” McGuinness told the judge.

That was around 7 p.m. Monday, according to police, who said they responded to the couple’s apartment on Griffen Street and found Mulvey lying on top of his dead girlfriend with a large kitchen knife nearby. Police said Mulvey put up a bit of a fight when they tried to remove him from McShane.

According to police reports, once taken into custody, Mulvey continued to confess repeatedly that night.

One report said that on the drive from the scene to the police department, Mulvey was crying and spontaneously stated, “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 tequila and vodka seltzers throughout the day, and she had run out of the house because “she was afraid of him when he was drinking because his anxiety turned to anger,” according to one report.

Mulvey told police they were lying in bed, and 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,” the 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 that’s when McShane ran out of the house, the report said. When she returned, Mulvey said he 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.”

Mulvey told police they’d been together for 25 years, breaking up when he was incarcerated in 2010 for two years, but reconnecting when he got out. He also said he’d known McShane since she was 16 and didn’t want to live without her, so he planned to kill himself, another report said.

The suicide statements led to Mulvey undergoing a mental health evaluation at the hospital Tuesday morning and pushed his arraignment one day.

In court Wednesday, the bail commissioner said Mulvey had nine convictions between 2006 and 2019, including possession of a weapon in a motor vehicle, which is a felony.

“Some of the defendant's convictions relate to the decedent in this particular case. The defendant has been convicted for domestic violence cases in the past involving this particular decedent,” McGuinness told the judge.

In October 2010, he was charged with assaulting two Norwalk officers after he allegedly pulled a knife on them at a Norwalk storage facility. Police responded there after a call about a domestic disturbance between Mulvey and his girlfriend. McShane’s family confirmed that was her. Mulvey went to trial in the case in 2012 and was acquitted of the felony charges but convicted of misdemeanors, leading to a two-year sentence. That ended up being time served since he was in custody since his arrest.

Most recently, Stratford police responded to the couple’s apartment complex in May after a call about Mulvey “pushing and shoving” McShane outside the apartment, according to another police report. He was arrested and a protective order issued. But police told News 12 the state’s attorney’s office said McShane wouldn’t cooperate with the prosecution, so the charge and protective order were dropped.

Piro said Mulvey beat her sister for years, but unfortunately McShane couldn't get out of the relationship.

“She struggled with things in life,” Piro said.

“She was a very strong girl, you know?” added Piro’s husband, Frank. “She raised herself pretty much, and she did whatever she had to do to survive, you know? But she couldn't survive this.”

McShane leaves behind two older sisters and an adult son.

“Our family’s never going to be okay,” Piro told News 12. “He deserves to be in prison the rest of his life.”

During the arraignment, McGuiness also argued that Mulvey needed to stay locked up.

“He is now a per se threat to the public and needs to be incapacitated during the pendency of this case, so I'm asking the court to keep the bond set at $1 million,” McGuinness stated.

The judge agreed and set Mulvey’s next court date for Nov. 4. He’s also been put on suicide watch.
