A number of gun violence prevention groups and advocates joined together for "wear orange day."
The online movement, marked with the hashtag #WearOrange, is the national day of awareness for gun violence prevention.
Gov. Dannel Malloy issued a proclamation declaring June 2 as Gun Violence Awareness Day in Connecticut.
Newtown First Selectwoman Pat Llodra issued a similar proclamation.
In Dec. 2012, 26 students and staff were gunned down at the Sandy Hook Elementary School in Newtown.
State officials held a news conference at St. Francis Hospital and Medical Center in Hartford.
Sen. Chris Murphy, Hartford Mayor Luke Bronin, Hartford police Chief James Rovella and Malloy were on hand to make a plea to reduce the violence.
Malloy said the #WearOrange movement was inspired by the friends of Hadiya Pendleton, a 15-year-old high school student from Chicago who was killed by gunfire. Her friends said they decided to honor her by wearing orange, the colors hunters wear to protect themselves and others.
Thursday would have been her 18th birthday.
More than 200 organizations and officials asked people nationwide to join them by wearing orange to honor her and the dozens of Americans killed by gun violence every day.
