NEW CANAAN — Police arrested a 57-year-old New Canaan man for allegedly supplying the heroin which led to his 25-year-old son’s death.

On Sept. 25 at 7:22 a.m., police and the New Canaan Volunteer Ambulance Corp were dispatched to Parade Hill Road on a report of an unresponsive man. There, police found Chris Lynch, unresponsive in the back bedroom. Lynch was not breathing and there was white, frothy vomit on the pillow under his head near his mouth. Medics unsuccessfully attempted to revive him and pronounced him dead on scene at 7:27 a.m.

According to the arrest warrant application, during the revival attempts, a person in the home yelled at medics “Do something! Why aren’t you doing anything? Give him Narcan!” The person in question would not elaborate further as to why Lynch would need Narcan, but made several more references to using the substance to revive the victim.

Investigators then arrived to determine cause of death. Investigators interviewed residents of the home, including Lynch’s father, Mark Lynch. Lynch said his son took Xanax and went to sleep around 8 p.m. on Sept. 24. When the older Lynch checked on his son during the night, he heard gurgling sounds coming as he was sleeping and said his breathing sounded irregular. Lynch went to bed around 4 a.m. He said he found his son unresponsive when he woke up the next morning and called police.

During the investigation, a “distraught” Lynch voluntarily turned over a green rubber coin purse from the top drawer of the nightstand next to his son’s bed. In the coin purse, police found a black straw and four folds of a white powder which police believed to be heroin. Lynch told police the substance was heroin and that it was “all” his. Lynch said he “allowed” his son to use some on the night of Sept. 24.

Lynch then consented to having the bedroom to be searched. The room Chris was found in was the older Lynch’s bedroom and Suboxone, a medication used to treat opioid dependence, was found in a bureau drawer in the room. Lynch then handed over his son’s cell phone, which was taken as evidence. Lynch then tried to tell police that the heroin was actually his son’s, despite his previous statement and the fact he knew where the coin purse containing the drugs was located.

An investigation into the younger Lynch’s death revealed that the cause of death was acute heroin intoxication, as confirmed by the medical examiner’s report. The state forensic lab confirmed the substance Lynch turned over to police was heroin. According to the arrest warrant application, Lynch and his son used the heroin together, despite confirmation from an attorney that Lynch knew his son was in treatment for a drug addiction and was sober. When asked about his son’s medical history, Lynch said his son had been battling a drug addiction for several years.

A later investigation also revealed the younger Lynch had been involved in other narcotics-related incidents and had been recently brought to the hospital by his family for an overdose. Based on the investigation and evidence the heroin he gave to his son caused his death, police applied for an arrest warrant for Lynch.

On Nov. 21, the warrant was reviewed by State Attorney Richard Colangelo and signed by Judge John F. Blawie of Stamford Superior Court. On Nov. 21 around 6:45 p.m., Lynch surrendered himself to police. He was charged with second-degree manslaughter, possession of narcotics and illegal distribution of hallucinogenic narcotics. Lynch was processed and posted a $150,000 bond. He is scheduled to appear in Norwalk Superior Court on Dec. 2.; @erin_kayata
