Saturday's shooting erupted after the annual West Indian Day parade in the city's North End. Police said 16-year-old Ezekiel Roberts of Hartford was killed, a 7-year-old boy was shot in the head and 15-month-old Zinia Jackson was shot in the left leg. Four other teens were shot.
Police were still looking for suspects and no arrests had been made.
Police said Roberts was affiliated with local gangs and was the intended target of the shooting, The Hartford Courant reported. No arrests have been made.
Perez and Police Chief Daryl K. Roberts announced new public safety measures on Monday, including a monthlong 9 p.m. emergency curfew that will begin Thursday. No one under 18 will be allowed on the streets without a parent or guardian, and violators will be taken to a community center where they will be kept until their parents or guardians pick them up.
Many U.S. cities have permanent curfews, but many are less restrictive than Hartford's temporary measure.
City officials said they also will be forming a "shooting team" with state prosecutors that will sharpen authorities' focus on solving shootings, punishing shooters and deterring such crimes. Perez, himself a former gang member, said the city will be asking the state to increase supervision of people on probation and creating a "Most Watched List" of suspects wanted for crimes or known to be associated with illegal activities.
Other actions include asking state officials to increase supervision of people on probation.
Hartford officials have been struggling to curb violence in the city of 125,000. In June, the city's former deputy mayor was beaten and robbed while walking to breakfast, and a surveillance camera recorded cars zooming around a 78-year-old pedestrian who was laying helpless in the street after being struck by a speeding car.
No arrests have been made in those incidents, which prompted Chief Roberts to suggest that the city lost its moral compass.
