Boston police, with help from state and federal law enforcement authorities, continue to search for the suspects in a shooting rampage that left a toddler and three adults dead.
Police department spokeswoman Elaine Driscoll says that police are combing through several leads.
“The homicide investigation is extremely active,” Driscoall said. “Our detectives are working around the clock. We are optimistic about progress that we’re making.”
Boston police, city officials, and members of the clergy have been walking through the neighborhood where the shooting took place, asking residents to come forward with any information that could lead to arrests.
Authorities say five people were shot in the city’s Mattapan neighborhood early Tuesday morning. One of the victims remains clinging to life, but police have said he is not expected to survive.
Relatives say the toddler killed was a 2-year-old boy who was shot while being held in his mother’s arms. His mother was one of the victims.
Police have not released the victims’ names and have not revealed a possible motive.
The shooting drew outrage from Boston Mayor Tom Menino who called the killer or killers “cowards.”
There have been 14 homicides in Mattapan this year, up from six at this time last year.
