Suffolk County police have identified a West Babylon man as a suspect in the stabbing death of his wife Saturday afternoon.

Police named Kerwyn Jaggernauth, 31, as the man who was found with self-inflicted stab wounds inside the couple’s split-level home on Sheffield Avenue. Jaggernauth has not been charged, and remains in critical condition at a hospital.

But police said Saturday that they suspect him in the death of his wife, Sonja Williams, 32.

Sunday afternoon, a long blood stain still stretched from the side gate of the house, extending across the street and ending in large smear in the driveway across the street.

A large truck arrived at the house around 2:30 p.m. Sunday and two men in hazmat suits began pouring chemicals on the stain and scrubbing the driveway. Later the workers used plywood to board up a gate in the fence surrounding the backyard.

A woman who answered the door at the house declined to comment.

Suffolk County Police Commissioner Tim Sini told reporters Saturday that Williams appeared to have been killed at about 2:30 p.m.

Sini also said he expected Jaggernauth to survive.

Karen Kluges, 36, lives adjacent to the house where Wilson died. She said she saw through her bedroom window on Saturday a woman trying to get into the house through a side entrance and screaming.

“A woman was out here banging on the door,” Kluges said Sunday afternoon. “I guess it was the grandma, because she said, ‘That’s my daughter, that’s my daughter and my grandbabies,’ over and over again. It was heartbreaking.”

Kluges said the scene was quickly overwhelmed with police vehicles.

Williams had two children, ages 12 and 5, one from a previous marriage and the other with Jaggernauth, police said.

Neither child was in the home during the attack, and both are now with relatives, police said.

Authorities did not know if the couple had a history of domestic violence, but Sini had said that would be investigated. Neighbors said the couple had been renting the house for about a year and didn’t know of any previous incidents.s
