LOWELL — A neighborhood remained shocked and grief-stricken Sunday, a day after a horrific dog attack that left a 7-year-old boy dead.

The child was mauled late Saturday afternoon after he apparently entered a fenced area where two pit bulls were kept next to a Clare Street home, according to a Saturday night statement from the Middlesex district attorney’s office.

One dog escaped but was captured and euthanized Saturday night, according to the statement. The other was taken by animal control.
