It's just after 9:30 p.m. on July 3, 2012.

Crowds are gathered along the lower end of Grafton Street in Worcester to watch the city's annual Independence Day fireworks display.

Jonathan Kapulka is standing in a parking lot near the entrance to Walgreens pharmacy. He's with a large group of family and friends. With him are his wife and two daughters.

In one of the most brazen and violent acts in recent history in Worcester, a man wearing a ski mask ran up behind Jonathan, shooting him three times.

The killer ran away up Grafton Street.

And for over 10 years, Jonathan's murder remains unsolved.
