STAMFORD — The past year has been a long journey Pam Bacco hoped would end with a harsher penalty for her ex-husband.

Instead, Mark Lynch, 58, accepted a deal Friday that will send him to prison for three years in the overdose death of their son.

The former New Canaan man pleaded guilty to criminally negligent homicide and sales of narcotics in connection with his 25-year-old son’s death in September 2016. Lynch faced up to ten years in prison if he was convicted at trial of second-degree manslaughter.

“This has been a long road, and this isn’t the way I exactly thought it was going to end,” Bacco said, “but hopefully now I can find some peace.”

However, Judge Richard Comerford did not immediately accept the plea agreement because Stamford State’s Attorney Richard Colangelo said Bacco did not initially support the sentence.

Comerford said he will wait until Lynch is sentenced on Dec. 15 to accept the plea deal. Lynch will also be sentenced to seven years of special parole when he’s released and will be returned to prison if he breaks the law.

Colangelo said Bacco was comfortable with the punishment when he spoke to her following the court hearing.

“This is a tragic situation,” Colangelo said. “There is no amount of time that Mark Lynch can serve that will bring back her son. This is a tragic situation that is occurring all too often in our society now.”

Christopher Lynch was among the more than 900 people who died of overdoses last year in Connecticut. Police said he was visiting his father when he was given the heroin that led to the fatal overdose.

“Mark’s guilty plea to negligent homicide is more consistent with what took place than the original charge of manslaughter second-degree,” Lynch’s defense attorney, Matthew Maddox, said. “Mark mourns the loss of his son every day and will always have to live with his part in his son’s death. He hopes that the conclusion of this case will help the many people who loved Chris to heal as best they can.”
