LOWELL (CBS) — A little boy from Lowell was remembered by his neighbors with a vigil where dogs killed him one day earlier.

The seven-year-old was attacked while inside a fenced area with the two pit bulls at a Clare Street home around 6 p.m. Saturday.

“Two 100, 120-pound pit bulls just getting his neck, his legs. It was actually horrific to watch,” recalled David Swiniarski, who lives nearby. “Everyone was screaming, no one knew what to do.”

Officials believe the little boy climbed into the area where the dogs were kept.

“He was cute, the whole thing is so so sad,” said one woman.

One neighbor said he couldn’t imagine the dogs would hurt anyone.

“The dogs to me were very mellow dogs, very nice. I used to play with the dogs sometimes,” said neighbor Roger Rodriguez. “It’s too bad, all of my prayers go to the family.”

Middlesex County District Attorney Marian Ryan commented Sunday night.

“Right now, our thoughts are just with the family of this little boy, the neighborhood, as well as our first responders. Just a terrible, terrible loss of a child,” she said.

One of the dogs has been euthanized and the other is with Lowell Animal Control.
