Police identify, arrest suspect of Wallingford teen homicide

New Haven

WALLINGFORD, Conn. (WTNH) — A Wallingford man is now under arrest in the death of a 17-year-old found dead in a lake near the Wallingford Senior Center last week. Police say the suspect is technically the uncle of the victim, and he confessed to the murder.

On Tuesday, police say the suspect, David Diaz-Perez, 21 of Wallingford, was arrested on May 11 for the murder of Nolvin Diaz, whose body was found by two kayakers partially submerged in water on Community Lake around 1 p.m. on May 3. Nolvin was reported missing by family members on April 25.

The missing person investigation revealed that Diaz had few friends and didn’t socialize much outside of the family. It further revealed that his cell phone had been turned off.

After the body was found, police say Nolvin had suffered numerous injuries to the head and face and had his own belt tied around his neck. An attempt was made to submerge his body in the lake. The Medical Examiner ruled his death a homicide caused by blunt injury to the head, sharp force injury to the face and ligature strangulation.

Police interviewed David Diaz-Perez, who was related to Nolvin, on May 11. Diaz-Perez allegedly admitted to killing Nolvin and provided intimate details that had not been released to the general public. He also physically showed the detectives where the incident occurred. Diaz-Perez explained to police that the incident happened on April 23, but he allegedly went back on May 2 to drag the body into the lake.

“Nolvin had suffered numerous injuries to the head and the face and had his own belt tied around his neck,” said Lt. Cheryl Bradley, spokesperson for the Wallingford Police Department.

The Diaz family is originally from Guatemala. Diaz was only 17, but he was not going to school.

“He worked in a neighboring community,” Lt. Bradley said. “He had been living in Wallingford for about a year. He was working, but was currently out of work because of the pandemic.”

While Diaz-Perez confessed to everything, he did not give a reason for killing his nephew. Wallingford’s Chief credits round-the-clock detective work with cracking the case but reminds everyone the Diaz family is now without two members.

“We truly are sympathetic to the Diaz family who are not only dealing with the death of one of their family members, but now contemplating that a different family member is responsible,” said Police Chief William Wright.

Diaz-Perez did not tell police why he killed his nephew. He is now charged with murder. He is being held on $2 million bond and is scheduled to be arraigned Wednesday in New Haven.
